2. How to Use this Training Tool This training tool is an awareness-level health and safety resource for “skilled support personnel” who will participate in a dirty bomb response.
This tool will help workers understand at an awareness level: what a dirty bomb is, the basics of radiation, how to protect against radioactive contamination and other hazards associated with a dirty bomb response.
Trainers may use this tool to aid in the development of a dirty bomb awareness level course or other awareness level materials (fact-sheets, table-top activities, etc.)
Trainer Notes:Trainer Notes:
3. Advanced/Additional Training Required for Those Involved in a Dirty Bomb Response This training tool does not replace the radiation-specific training, additional duty specific training or PPE specific training requirements.
Regardless of work scope, there are many topics covered in this awareness training tool that have corresponding OSHA standards which must be met in order to safely and legally perform associated job duties. Trainer Notes:

4. Employer and Worker Responsibilities Employers and workers have responsibilities under the OSH Act.
The Occupational Safety and Health Act requires employers provide a safe and healthful workplace free of recognized hazards and follow OSHA standards. Employers' responsibilities also include providing training, medical examinations and recordkeeping.
Workers must follow the employer's safety and health rules and wear or use all required gear and equipment; follow safe work practices for their job, as directed by their employer; report hazardous conditions to a supervisor; and report hazardous conditions to OSHA if employers do not fix them.

5. Module 1 Radiological Dispersion Device (RDD)
“Dirty Bomb” Awareness Trainer Notes:Trainer Notes:
6. What is an RDD? Characteristics of RDDs:
A terrorist event
Low technology
Low cost to make
Wide range of usable radioactive materials
Contamination restricts use of area until it can be decontaminated
Cleanup problem
Economic impact
Psychological impact
Spread fear (perceived danger)
Trainer Notes:
An RDD (dirty bomb) is any device, including any weapon or equipment, other than a nuclear explosive device, specifically designed to employ radioactive material by disseminating it to cause destruction, damage, or injury by means of the radiation produced by the decay of such material.
Since this will be a terrorist event, training for response workers on evidence preservation may be required.

7. An RDD is Not a Nuclear Device A nuclear device or Improvised Nuclear Device (IND) releases an enormous amount of energy (atomic bomb) while an RDD releases a comparatively small amount of energy. Trainer Notes:
Make sure the trainees understand that the difference between a dirty bomb and a nuclear device is huge.
If an IND is improperly constructed it may not go nuclear; instead it may detonate and disperse radioactive material in a similar fashion to a RDD.Trainer Notes:

8. Characteristics of a Dirty Bomb Incident Disperses radioactive contaminated dust into the air and onto surfaces.
May disperse larger projectiles of either the delivery device (bomb parts) or actual pieces of the radioactive material.
Most RDDs will use low-level radioactive materials.
Dispersal of radioactive material may be explosive (active, associated with a bomb) or non-explosive (passive, released into a ventilation system or placed in a waste basket).
May destroy or damage structures
(buildings, infrastructure, utilities, etc).
Casualties and damage mainly takes place with initial detonation and the short period thereafter. However low level internal exposures may increase cancer risk. Trainer Notes:Trainer Notes:
9. Characteristics of a Dirty Bomb Incident (continued) May release other hazardous chemicals by damaging nearby chemical storage containers, creating new chemicals in the explosion, etc.
Many of the radioactive materials used to make a dirty bomb are also heavy metals which are toxic at low levels.
Clean up is difficult and costly.
May include a secondary device (RDD or other agent) with intent to harm responders.
Trainer Notes:Trainer Notes:
10. What is a Secondary Device? Secondary devices are bombs placed at the scene of an ongoing emergency response. Designed to explode after a primary explosion or other major emergency response event has attracted a large number of responders to the scene, the intent is to inflict injury, damage, and fear among responders. Trainer Notes:Trainer Notes:
11. Warning Signs of Possible Explosive Materials or Secondary Devices Any abandoned container out of place for the surroundings.
Obvious devices containing blasting caps, timers, booster charges, etc.
Abandoned vehicles not clearly belonging in the immediate environment.
Strong chemical odors for which there is no apparent reason.
Unusual or foreign devices attached to pressurized containers, bulk storage containers or supply pipes.
Trip wires or other booby traps, suspicious mailing containers.
Trainer Notes:
Bombs can be made to resemble ordinary objects, lunch boxes, paper bags, etc.
Second responders working at an explosive incident will have difficulty recognizing out of the ordinary objects. Typically these devices will be hidden in out of view locations, or camouflaged by placing the devices in ordinary objects such as vehicles, flashlights, briefcases, flowerpots, or garbage cans. Usually the devices are detonated by a time delay, although radio-controlled devices or cell phone activated devices could also be used.
Guidelines for response from the U.S. Fire Administration:
These guidelines recommend that responders:
(1) Anticipate the presence of a secondary device at any suspicious
incident.
(2) Search for a secondary device before moving into the incident area.
(3) Avoid touching or moving anything that may conceal an explosive device.
(4) Effectively manage the scene with boundaries, exclusion zones, triage areas, etc.
(5) Evacuate victims and non-essential personnel as quickly as possible.
(6) Preserve the scene as much as possible for evidence collection and crime investigation.

12. Module 2 Dirty Bomb (RDD)
Radioactivity Basics
Trainer Notes:Trainer Notes:
13. Radioactive Hazards: After an RDD Explodes The dispersion of radioactive material will depend on many factors; primarily the physical form of the radioactive material.
The majority of material will likely be
dispersed over a large area as
radioactive dust.
The greatest amount of dust will
settle close to the explosion but small
amounts can travel large distances,
especially small particles.
Large pieces of radioactive material can
be thrown and emit significant radiation
Trainer Notes:Trainer Notes:
14. Radioactive Material Defined Trainer Notes:
Radioactive material - Any material that contains radioactive (unstable) atoms. Radioactive materials are everywhere. Usually, we only encounter them in very small amounts. Since radioactive material contains unstable atoms, it emits radiation.

16. RDD Radiation Exposure Radiation exposure to skilled support workers will come from:
radioactive dust
large pieces of the bomb’s radioactive materials. Trainer Notes:
The following explanations were taken from the CDC Radioactive Contamination and Radiation Exposure Fact Sheet at http://www.bt.cdc.gov/radiation/contamination.asp
Radioactive contamination and radiation exposure could occur if radioactive materials are released into the environment as the result of an accident, an event in nature, or an act of terrorism. Such a release could expose people and contaminate their surroundings and personal property.
What Radioactive Contamination Is
Radioactive contamination occurs when radioactive material is deposited on or in an object or a person. Radioactive materials released into the environment can cause air, water, surfaces, soil, plants, buildings, people, or animals to become contaminated. A contaminated person has radioactive materials on or inside their body.
What External Contamination Is
External contamination occurs when radioactive material, in the form of dust, powder, or liquid, comes into contact with a person's skin, hair, or clothing. In other words, the contact is external to a person's body. People who are externally contaminated can become internally contaminated if radioactive material gets into their bodies.
What Internal Contamination Is
Internal contamination occurs when people swallow or breathe in radioactive materials, or when radioactive materials enter the body through an open wound or are absorbed through the skin. Some types of radioactive materials stay in the body and are deposited in different body organs. Other types are eliminated from the body in blood, sweat, urine, and feces.
What Radiation Exposure Is
Radioactive materials give off a form of energy that travels in waves or particles. This energy is called radiation. When a person is exposed to radiation, the energy penetrates the body. For example, when a person has an x-ray, he or she is exposed to radiation.
How Contamination Differs From Exposure
A person exposed to radiation is not necessarily contaminated with radioactive material. A person who has been exposed to radiation has had radioactive waves or particles penetrate the body, like having an x-ray. For a person to be contaminated, radioactive material must be on or inside of his or her body. A contaminated person is exposed to radiation released by the radioactive material on or inside the body. An uncontaminated person can be exposed by being too close to radioactive material or a contaminated person, place, or thing.Trainer Notes:

17. Contamination and Exposure Contamination takes place when contact is made with radioactive material and it is deposited on the skin, clothing, surfaces, etc.
Exposure to radiation occurs when a person or an object is close enough to radioactive material to be affected by it without touching it. Trainer Notes:

18. Contamination and Exposure (continued) If radioactive contamination gets onto your clothes, intact skin or surfaces it can be removed through decontamination procedures. (See Module 3.)
If radioactive contamination gets into your body through inhalation (lungs), digestive system (through eating or mucus) or goes directly into your blood stream (through a cut) it becomes an internal contamination hazard and may lead to high exposure. Trainer Notes:Trainer Notes:
19. What is Radiation? Radiation is energy in motion.
Radiation may be in the form of
particles or rays/waves.
There are two types of radiation:
Non-ionizing radiation
Ionizing radiation Trainer Notes:
Below are further defined terms used in the slide:
Radiation - Radiation is energy in the form of waves or particles given off during radioactive decay, or as a consequence of certain physical processes that we can control. Examples of these are x-ray machines and particle accelerators.
Wave radiations include gamma and x-rays. A common term used to describe this type of radiation is photon radiation.
Particle radiation can consist of charged or uncharged particles which are emitted with very high velocity.
Radiation travels from its source at very high speed, and depending on the type, may be able to penetrate easily through very dense materials.

21. How Can I Protect Myself? Prevent inhalation or ingestion of radioactive dust or deposition of radioactive dust on skin or a wound.
Use the Hierarchy of Controls:
Eliminate the hazard (leave the area)
Engineer the hazard out (use wet methods to control dust)
Administrative (use standard operating procedures (SOPs))
Personal Protective Equipment (PPE) (i.e., respirators)
Trainer Notes:Trainer Notes:
22. How Can I Protect Myself? (continued) Avoid areas with radioactive contamination.
Decontaminate yourself in accordance with your site decontamination plan.
Use radiation detection devices.
Time, Distance and Shielding.
Note: Time, distance and shielding may not relate to internal radiation hazards.
Trainer Notes:Trainer Notes:
23. How Can I Protect Myself - Dust Dust can be both contamination on your skin or contamination breathed or ingested into your body.
Ensure that all measures are taken to minimize dust generation (use wet methods, etc.)
As a final step, wear the appropriate respirator to avoid inhaling dust and protective outer clothing to prevent skin contamination.
After exposure, take all steps to remove dust.
Trainer Notes:Trainer Notes:
24. How Can I Protect Myself – Bomb Fragments Larger pieces may have a higher associated radiological hazard than the dust created from an RDD explosion.
If you are not certain whether or not a piece of material is radioactive, leave it alone and report it so it can be tested. Do not handle suspect material.
Do not remove shrapnel from a wound unless you are medically qualified to do so. The hazard from radiation will probably be less than the hazard of improperly removing shrapnel. Seek medical attention. Trainer Notes:Trainer Notes:
25. More on Time Limit your exposure to the radioactive source.
By limiting your time, you limit your dose. Trainer Notes:Trainer Notes:
26. More on Distance – STAND BACK! By increasing the distance between you and the radioactive material you will reduce your dose-rate.
In fact, if you double your
distance from the source,
you will reduce your dose-rate
to one/fourth. Trainer Notes:
Doubling your distance from the source, reduces your dose-rate by three/fourths. This is called the inverse square law.Trainer Notes:

28. Units to Measure Ionizing Radiation The following are units used to measure radiation dose. These are some of the terms you might hear on site:
Rad - Units for absorbed doses of all radiation
Roentgen - Units of exposure to gamma radiation
Rem (mrem) - Unit of dose related to biological risk Trainer Notes:
Rad: An acronym for Radiation Absorbed Dose.
Roentgen (R): A unit of exposure to ionizing gamma radiation in air.
Rem: An acronym for Roentgen Equivalent Mammal. The unit of dose of any type of ionizing radiation that produces the same biological effect as a unit of absorbed dose of ordinary X-rays.

Roentgen (R): A unit of exposure to ionizing gamma radiation in air.
Rem: An acronym for Roentgen Equivalent Mammal. The unit of dose of any type of ionizing radiation that produces the same biological effect as a unit of absorbed dose of ordinary X-rays.
29. Radiation Dose vs. Dose Rate Radiation Dose (cumulative):
The amount of radiation energy deposited in the body
Often measured in millirem
Dose Rate:
The rate at which radiation energy is deposited in the body
Often measured in millirem per hour Trainer Notes:
Units of Radiation
To quantify amounts of radiation, the term rem or millirem is used. It has a specific definition, but we’re concerned with how many rather than a definition.
Note: rem = roentgen equivalent man
rem = rad X RBE
rad = radiation absorbed dose (deposition of 100 ergs of radiation energy per gram of absorbed material)
RBE = relative biological effectiveness
Other terms you may see or encounter are:
Gray (Gy): 1 rad = 1cGy or 1 Gy = 100 rads
Sievert (Sv): 1 Sv = 100 rems
So again for our purposes, 1 Sv = 1 Gy

30. Radiation Dose Acute
High dose rate
Short period of exposure
Visible signs of exposure
Nausea
Fatigue
Hair loss
Burns
Very damaging to tissue
Cells have less time to repair
Immune system damaged Chronic
Low dose rate
Long period of exposure
Less immediately damaging to tissue
No immediate visible effects
May cause cancer
Trainer Notes:
Acute radiation doses
An acute effect is a physical reaction due to massive cell damage. This damage may be caused by a large radiation dose received in a short period of time. Large doses of radiation received in a short period of time are called acute doses. The body can't repair
or replace cells fast enough from an acute dose and physical effects such as reduced blood count and hair loss may occur.
Slight blood changes may be seen at acute doses of 10,000-25,000 mrem but an individual would not otherwise be affected.
Radiation sickness
At acute doses greater than 100,000 mrem, about half of the people would experience nausea (due to damage of the intestinal lining). Radiation therapy patients often receive whole body equivalent doses in this range and above, although doses to the region of a
tumor are many times higher than this. If the acute dose to the whole body is very large (on the order of 500,000 mrem or larger) it
may cause so much damage that the body cannot recover. An example is the 30 firefighters at Chernobyl who received acute doses in excess of 800,000 mrem. These individuals succumbed to the effects of the burns they received compounded by their radiation dose.
After an acute dose, damaged cells will be replaced by new cells and the body will repair itself, although this may take a number of months. Only in those extreme cases, such as with the Chernobyl firefighters, would the dose be so high as to make recovery unlikely.
Acute doses to only part of the body
It is possible in that radiation exposure may be only to a limited part of the body such as the hands. There have been accidents, particularly with X-ray machines, in which individuals have exposed their fingers to part of the intense radiation beam. In some of
these cases individuals have received doses of millions of mrem to their fingers and some individuals have lost their finger or fingers. It is important for individuals who work with x-ray or similar equipment to be trained in the safe use of this equipment.
Chronic radiation doses
A chronic radiation dose is typically a small amount of radiation received over a long period of time. An example of a chronic dose is the dose we receive from natural background every day of our lives or the dose we receive from occupational exposure.
Chronic dose versus acute dose
The body is better equipped to handle a chronic dose than an acute dose. The body has time to repair damage because a smaller percentage of the cells need repair at any given time. The body has time to replace dead or non-functioning cells with new healthy cells.
It is only when the dose of radiation is high and is received very rapidly that the cellular repair mechanisms are overwhelmed and the cell dies before repair can occur. A chronic dose of radiation does not result in detectable physical changes to the body such as is seen
with acute doses. Because of cell repair, even sophisticated analysis of the blood do not reveal any biological effects.

31. What the Exposure Levels Mean Trainer Notes:
Trainer Notes:
32. Atomic Structure Atoms consist of:
A nucleus (center) made of:
Protons (+charge)
Neutrons (neutral)
Electrons (-charge) orbiting the nucleus.
Trainer Notes:Trainer Notes:
33. What Makes an Atom Unstable? If there are too many or too few neutrons for the number of protons the atom will give off excess energy in the form of:
Particles
Rays/waves
This process is called radioactive decay (the release of radiation). Trainer Notes:Trainer Notes:
34. Ionizing Radiation It is strong enough to detach an electron from an atom.
When an atom loses an electron, it has a positive charge and is called an ion.
The ion and its lost electron are called an ion pair.
Ionizing radiation can damage living tissue.

36. What is Ionization? Ionization occurs when atoms absorb sufficient energy from particle or wave radiation to break their molecular bonds and give off an electron.
This causes changes or destruction of molecules.
Ionization can damage living tissue. Trainer Notes:
Below is a further definition of Ionizing radiation.
Ionization - The process of ionization is important in understanding radiation, because it is this process that differentiates ionizing radiation from other types. Ionization is the process of removing electrons from atoms. If enough energy is supplied to remove electrons from the atom the remaining atom has a + charge. The positive charges atom and the negatively charges electron are called an ion pair. Ionization should not be confused with radiation. Ions (or ion pairs) can be the result of radiation exposure and allow the detection of radiation.
Typically, we classify types of radiation as ionizing or non -ionizing radiation depending on whether or not the radiation can form ion pairs in common material such as air or tissue.
Ionizing radiation - Radiation which has enough energy to ionize an atom is called ionizing radiation. The four basic types of ionizing radiation that are of primary concern for us are alpha particles, beta particles, gamma rays (includes x -rays) and neutron particles.
Non-ionizing radiation - Radiation that doesn't have the amount of energy needed to ionize an atom. Examples of non-ionizing radiation are ultraviolet rays, microwaves and visible light.

53. Incident Command System Structure Trainer Notes:
The National Incident Management System (NIMS) requires the use of the Incident Command System at domestic emergencies involving multi-jurisdictional participation.
Effective coordination (of both personnel and equipment) among local, state, and federal responders at the scene of a response is a key factor in ensuring successful responses to major incidents. An Incident Command System/Unified Command (ICS/UC) is the tool used to manage all emergency response incidents. Understanding the concepts of ICS/UC is as important for local responders, who generally arrive on-scene first and thus are most likely to implement the management system, as it is for state and federal organizations and any skilled support personnel that may be joining the response.
ICS is a standardized on-scene incident management concept designed specifically to allow responders to adopt an integrated organizational structure without being hindered by jurisdictional boundaries.
An ICS allows integrated communication and planning by establishing a manageable span of control. An ICS divides an emergency response into five manageable functions: Command, Operations, Planning, Logistics, and Finance and Administration.
You can find more information on ICS at http://www.osha.gov/SLTC/etools/ics/about.html.
The following training (and more) is available from FEMA’s Emergency Management Institute: ICS-100, Introduction to ICS; ICS-200, Basic ICS and IS-700: NIMS An Introduction. Information on who must take what training can be found at http://www.fema.gov/emergency/nims/faq/training.shtm.

61. Decontamination Decontamination or Decon is the process of removing, destroying, or reducing the activity of materials such as toxic chemicals or radioactive contamination that could endanger an individual or the environment. Decontamination of personnel is necessary to keep the radiation from spreading to other locations.
In the event of a dirty bomb the
heaviest contamination will occur:
Within the immediate blast area
of the detonated device or area
of dispersion
Handling contaminated people
or property near the dispersion
Trainer Notes:
The following decontamination information is from the Medical Management of Radiological Casualties Handbook 2nd Ed.
Military Medical Operations
Armed Forces Radiobiology Research Institute
Bethesda, Maryland 20889–5603
http://www.afrri.usuhs.mil
Removal of outer clothing and rapid washing of exposed skin and hair removes 95% of contamination. The 0.5% hypochlorite solution used for chemicals will also remove
radiological contaminants. Care must be taken to not irritate the skin. If the skin becomes erythematous, some radionuclides can be absorbed directly through the skin.
Surgical irrigation solutions should be used in liberal amounts in wounds, the abdomen, and the chest. All such solutions should be removed by suction instead of sponging and wiping. Only copious amounts of water, normal saline, or eye solutions are recommended for the eye.

A Decontamination plan tells workers what methods should be used for decontamination at a worksite.
63. Decontamination (continued) Site workers who use the site’s SOPs are less likely to be contaminated than site workers who do not use these practices. Workers can take steps to minimize their exposure during decontamination through using contact minimization techniques such as:
Remote handling techniques which reduce hand-to-material contact such as using shovels, wheelbarrows, Bobcats, etc.
Avoiding handling sharp debris since external radiation can become an internal hazard through punctured skin.
Wearing an outer layer of disposable clothing (PPE).
Encasing tools/equipment in plastic (i.e. place sampling equipment in a plastic bag).
Trainer Notes:Trainer Notes:
64. Decontaminating an Injury If you have a cut or punctured skin take precautions to prevent radioactive external contamination from becoming a radioactive internal exposure hazard:
Seek qualified medical treatment
Do not abrade the skin or wound
Do not force decon solution into
the wound (this will direct radioactive
contamination into the body!)
Direct decon solution to flow away
from the wound by using gravity Trainer Notes:
The following decontamination information on decontamination wounds is adopted from the Medical Management of Radiological Casualties Handbook 2nd Ed.

http://www.afrri.usuhs.mil
Wound Decontamination
All casualties entering a medical unit after experiencing a radiological attack are to be considered contaminated unless there is certification of noncontamination. The initial management of a casualty contaminated by radiological agents is to perform all immediate life/limbsaving actions without regard to contamination. Removal of protective clothing (PPE) and other exterior garments during the course of resuscitation will remove nearly all contamination except where the suit has been breached.
Initial Decontamination
During initial decontamination in the receiving areas, bandages are removed and the wounds are flushed; the bandages are replaced only if bleeding recurs.
General Considerations
Only highly energetic gamma emitters present any immediate hazard in wound contamination. Local wound contamination is by particulate matter, or possible shrapnel from bomb, that should be removed if possible. Alpha and beta emitters left in the wound will cause extensive local damage and may be absorbed into the systemic circulation and redistributed as internal contaminants. If possible, a radiation detection probe should be carefully placed into the dried wound, without touching any of the wound surfaces. DO NOT CONTAMINATE THE PROBE with radioactive particles, body fluids! Tissue fluids or protective gloves may prevent the detection of alpha and weak beta particles. After determination that adequate decontamination has been obtained, the wound should again be thoroughly irrigated with saline or other physiologic solution. Aggressive surgery such as amputation or extensive exploration should not be undertaken to “eliminate radioactive contamination.” The surgical damage will far exceed any potential decrease in lifetime radiological exposure risk. Partial-thickness burns should be thoroughly irrigated and cleaned with mild solutions to minimize irritation of the burned skin. Blisters should be left closed; open blisters should be irrigated and treated in accordance with appropriate burn protocols. In full-thickness burns, radioactive contaminants will slough in the eschar. As there is no circulation in the burned tissue, contaminants will remain in the layers of dead tissue. Excision of wounds is appropriate when surgically reasonable. Radioactive contaminants will be in the wound surfaces and will be removed with the tissue.

71. Chemical Hazards and the Hazcom Standard There may be a release of hazardous chemicals from the detonation device or from a secondary device.
The material that forms the dust during an RDD release may also be toxic (i.e. many radioactive materials are also heavy metals).
Specific Hazard Communication training is required for any potential chemicals that you may come in contact with.
Understand how to locate, read and apply information in Material Safety Data Sheets (MSDS). MSDS provide both workers and emergency personnel with the proper procedures for handling or working with a particular substance. Trainer Notes:
Some symptoms of short-term chemical exposure include: irritated tissues (skin, eyes, nose, throat and upper respiratory track), flu-like symptoms, difficulty breathing, fatigue, loss of coordination, mental confusion, sleeplessness, dizziness, chemical burns, asphyxiation, and impaired vision. Long-term symptoms depend on the extent and duration of exposure to the chemical.
Refer to the OSHA Hazard Communication Standard 29 CFR 1910.1200 for more information on the requirements of hazardous material handling and use. Trainer Notes:

72. Carbon Monoxide (CO) Exposure
Trainer Notes:
General Recommendations:
Use CO warning sensors when using or working around combustion sources.
Shut off engine immediately if symptoms of exposure appear.
Warning! Do not use gasoline generators or portable fuel driven tools in confined spaces or poorly ventilated areas.
Warning! Do not work in areas near exhaust (CO poisoning occurs even outdoors if engines generate high concentrations of CO and worker is in the area of the exhaust gases). With symptoms of exposure, shut off the engine.
OSHA 1926.302(c)
If using a fuel powered tool in an enclosed area such as a trench, be aware that carbon monoxide generated can displace or deplete oxygen. Mechanical ventilation and testing needs to be done.
Note: CO poisoning can occur in small spaces, such as a crawl space or large areas, such as a big parking garage.

77. Excavation Hazards (continued)1 General Trenching and Excavation Rules
Keep heavy equipment away from trench edges.
Keep surcharge loads at least 2 feet (0.6 meters) from trench edges.
Know where underground utilities are located.
Test for low oxygen, hazardous fumes and toxic gases.
Inspect trenches at the start of each shift.
Inspect trenches following a rainstorm.
Do not work under raised loads.
1. OSHA Trenching and Excavation Factsheet
Trainer Notes:
Surcharge loads are additional loads nearby the excavation site, such as soil from the excavation and equipment.
In some instances, the design of vertical walls of the excavation will be affected by wheel loads or other surcharge loads on the ground surface. These loads should be considered in the structural stability calculations and in the detailed design as appropriate. They should be based on the heaviest piece of equipment likely to be placed on the fill during construction.1

Check for overhead objects before use.
Stay far from debris piles, drop-offs, and floor openings.
Never use near electric lines unless they are deenergized or adequate clearance is maintained.
Refuel tanks only when the unit is off and charge batteries in a well ventilated area away from open flames.
Elevate the lift only when it is on a firm and level surface.
Whenever working out of an aerial, a full body harness must be worn and properly attached to the basket.
Never drive the aerial lift when it is elevated above the limit the manufacturer considers safe.
Trainer Notes:
Trainer Notes:
84. Falls from Heights Six Feet and Higher Employees shall be protected from falls greater
than six feet to a lower level.
Guardrail Systems
Safety Net Systems
Fall Arrest Systems (less effective
than guardrail and safety net systems)
Cover or guard any openings or floor
holes as soon as they are created.
Make sure floor hole covers support two times
the weight of employees, equipment, and materials
Be careful when stepping into areas that are unstable/uneven or where the surface cannot be visualized (i.e., areas covered by water).
Workers should prevent items from falling onto people below. Trainer Notes:
Trainer Notes:
85. Ladder Safety Position portable ladders so the side rails extend at least 3 feet above the landing.
Secure side rails at the top to a rigid support and use a grab device when 3 foot extension is not possible.
Do not apply more weight on the ladder than it is designed to support and make sure that the weight on the ladder will not cause it to slip off its support.
Before each use, inspect ladders for cracked, broken, or defective parts.
Use only ladders that comply with OSHA standards.
Trainer Notes:
Trainer Notes:
86. Electrical Hazards Electrocution is a common safety hazard on many worksites.
Avoid working with electricity in wet environments. If this must be done, use electrical cords approved for wet conditions.
Electrical cords and plugs must meet OSHA standards.
Use double insulated tools. Check the Underwriter’s Label to be sure the tool is double insulated.
Use Ground Fault Circuit Interrupters (GFCIs) on all power tools and cords as close to the panel as possible. Trainer Notes:
Treat all power lines and cables as energized until proven otherwise. Workers most at risk are removing debris from roadsides and in the process of pruning trees.
When an electrical shock enters the body it may produce different types of injuries. Electrocution results in internal and external injury to body parts or the entire body – often resulting in death. After receiving a “jolt” of electricity all or part of the body may be temporarily paralyzed and this may cause loss of grip or stability. A person may also involuntarily move as a result of receiving an electrical shock, resulting in a fall. Internal or external burns may result from contact with electricity.
Electricity travels in closed circuits, and its normal route is through a conductor. Electric shock occurs when the body becomes a part of the circuit.
Grounding is a physical connection to the earth, which is at zero volts.
The metal parts of electric tools and machines may become energized if there is a break in the insulation of the tool or machine wiring. A worker using these tools and machines is made less vulnerable to electric shock when there is a low-resistance path from the metallic case of the tool or machine to the ground. This is done through the use of an equipment grounding conductor—a low-resistance wire that causes the unwanted current to pass directly to the ground, thereby greatly reducing the amount of current passing through the body of the person in contact with the tool or machine.
OSHA 1926 Subpart K - Electrical
1926.416, 1926.417
Employees must not work near any part of an electric power circuit that the employee could contact in the course of work, unless the employee is protected against electric shock by de-energizing the circuit and grounding it or by guarding it effectively by insulation or other means.
* In work areas where the exact location of underground electric power lines is unknown, employees using jack-hammers, bars, or other hand tools which may contact a line shall be provided with insulated protective gloves.
* Before work is begun, inquire or observe by instruments whether any part of an energized electric power circuit is so located that the performance of the work may bring any person, tool, or machine into physical or electrical contact with the electric power circuit. Post and maintain proper warning signs where such a circuit exists. The employer shall advise employees of the location of such lines, the hazards involved, and the protective measures to be taken.

89. Driving and Traffic Issues Worksites must be posted with legible traffic signs at points of hazard. Flag persons or Flaggers are used when signs, signals, and barricades do not provide adequate protection for workers. Traffic issues workers may experience include:
Heavy traffic
Inexperienced or poor drivers Trainer Notes:
Worker transportation to the jobsite and around the jobsite present safety hazards that can be reduced through proper planning.
Workers who drive in the course of their duties shall possess valid licenses appropriate for the vehicles they are driving (including a commercial driver’s license, if required). Drivers shall comply with all applicable traffic safety regulations. Employers shall ensure compliance with state laws governing the use of seat belts. Vehicles should be equipped with a sufficient number of seats for each passenger.
Extra care should be exercised when driving on roads that may have been damaged by the hurricane. Roads may be washed out, undermined, or impassable. If possible, avoid driving into standing water due to the potential for unseen hazards. Be alert for debris and down power lines. Traffic may be heavy, especially around checkpoints. Traffic signs may be knocked down or not visible, and traffic signal lights may be inoperative. Street signs and landmarks may not be available. Allow extra time when traveling and drive defensively.
Sufficient parking areas should be arranged for workers in a location convenient to where they report for work. Parking areas shall be adequately lit and graded.Traffic issues include: movement of unusual vehicles; oversized loads such as mobile homes, heavy operating equipment.
Be prepared for delays.
Watch for other drivers
Flaggers may be hidden or obstructed by larger vehicles
Hazards
Congestion
Multiple entrances/exits to roadway
Power lines
Uncontrolled grapples with debris
Worker with multiple tasks – flagging & truck loading
No signage entering the zone
2 way traffic
Limited Visibility for traffic

90. Heavy Equipment Use OSHA requires machinery to be inspected by a qualified worker before each use.
Be alert to the activities around you.
Do not exceed the load capacity of lifting equipment.
Do not walk under or through areas where heavy equipment are lifting objects.
Do not climb onto or ride loads being lifted or moved. Do not ride on equipment or in bucket. Trainer Notes:
OSHA requires machinery to be inspected by a qualified worker before each use.
Operate equipment correctly and safely.
Special Notes for Bobcats:
Bobcats are a small, common piece of front-end-loading equipment. In many cases, for clean up of a contaminated avian flu zone, bobcats would be a logical choice to perform much of the assisted material handling. Below are special precautions related to the safe operation of bobcats.
A bobcat is a one person machine, no riding in bucket or on machine.
Operate at a ground speed consistant with working conditions and terrain.
Avoid crossing exposed railroad tracks, ditches, ridges or curbs if possible. If crossing cannot be avoided, reduce speed and cross at an angle.
Only qualified people are to operate a bobcat. Handled improperly, this machine could cause severe injury or fatality. Don’t let the small size of the machine fool you!
NEVER move or swing loads above the heads of other workers.
Avoid slopes with steep or unstable surfaces, do not drive across slopes. Go directly up and down a slope or ramp with the heavy end of the machine uphill.
When operating the bobcat, always carry the bucket low or maximum visibility and stability. Be sure operators vision is not obstructed when traveling or working. Never attempt to make sharp turns or travel on steep slopes with a raised load.
Extreme caution is required when back filling, as the weight of the loader could cause new construction to fail.
When under-cutting high banks, watch for dangers such as falling rocks, overhanging trees or a cave-in.

96. Noise Exposure Wear appropriate hearing protection in noisy work environments.
Examples: power saws, earth-moving equipment, pneumatic tools.
A worksite is considered noisy if you have to shout to be heard within three feet. Trainer Notes:
OSHA 29 1926.101 and 1926.52
Employee exposure to excessive noise depends upon several factors:
How loud is the noise? Do you have to raise your voice to be heard 3 feet away?
What is the duration of each employee’s exposure to noise?
Do employees move between separate work areas with different noise levels?
Is noise generated from one source or multiple sources?
Hearing protection: Earplugs, earmuffs, or a combination, should be used when employees are exposed to high levels of ambient noise. Reference OSHA 29 CFR 1910.95.

Whenever possible, take breaks away from the work area; eat and drink in the cleanest area possible
Recognize and accept what you cannot change-the chain of command, organizational structure, waiting, equipment failures, etc.
Talk to people when YOU feel like it; you decide when you want to discuss your experience
If your employer provides you with formal mental health support, use it
Give yourself permission to feel rotten; you are in a difficult situation
Recurring thoughts, dreams, or flashbacks are normal-do not try to fight them; they will decrease over time.
Communicate with your loved ones at home as frequently as possible
Trainer Notes:
Talking about an event may be reliving it.Trainer Notes:

101. How to Cope With Traumatic Stress – What You can Do at Home Reach out - people really do care.
Reconnect with family, spiritual, and community supports.
Consider keeping a journal.
Do not make any big life decisions.
Make as many daily decisions as possible to give yourself a feeling of control over your life.
Spend time with others or alone doing things you enjoy to refresh and recharge yourself.
Be aware that you may feel particularly fearful for your family; this is normal and will pass in time.
Remember that ”getting back to normal” takes time. Gradually work back into your routine. Let others carry more weight for a while at home and at work. Trainer Notes:
Trainer Notes:
102. How to Cope With Traumatic Stress – What You can do at Home (continued) Be aware that recovery is not a straight path but a matter of two steps forward and one back. You will make progress.
Appreciate a sense of humor in yourself and others. It is OK to laugh again.
Your family will experience the disaster along with you. You need to support each other. This is a time for patience, understanding, and communication.
Avoid overuse of drugs or alcohol. You do not need to complicate your situation with a substance abuse problem.
Get plenty of rest and normal exercise. Eat well balanced, regular meals. Trainer Notes:

105. Summary Proper training is a key component of a safe response.
Radioactive contamination (dust) is the main hazard.
The hazards and issues covered in this training tool are dynamic and require vigilance and flexibility.
The key to a safe response is attention to the safety issues of your work environment.
In addition to the similar physical hazards of a construction or demolition site, there is the added factor of radiological contamination, threat of secondary devices and potential release of hazardous chemicals. Trainer Notes:
All workers must adhere to the following work rules:
Follow their employer’s safety & health policies at all times.
Follow supervisors’ instructions and adhere to the chain of command.
Follow personnel accountability instructions; check-in and check-out.
Obtain vaccinations in conformance with the employer’s medical direction.
Promptly report all injuries, accidents, and near misses. Seek medical attention as needed.
Report all unsafe conditions. Do not perform tasks until proper safety & health controls have been put into place. Employees may refuse to perform tasks that expose them to an imminent danger.
Wear all personal protective equipment (PPE) needed for the task.
Maintain constant awareness of your surroundings.

107. Why This Training Tool Was Created This training tool was created by the NIEHS National Clearinghouse for Worker Safety and Health Training under contract no. 273-05-C-0017 from the National Institute for Environmental Health Sciences Worker Education and Training Program (WETP). WETP has trained over a million emergency responders and hazardous waste workers since 1987 to do their jobs safely. WETP is a part of the Department of Health and Human Services, which is a cooperating agency under the Worker Safety and Health Support Annex of the National Response Plan. As part of the coordinated effort, WETP created this training tool for those who may be involved in a response to an RDD. Trainer Notes:
