Hazard Communication (Employee Right-to-Know)

AEE Safety Training Program

2008

employee right to know
Employee Right-to-Know
  • OSHA’s Hazard Communication Standard (HCS) is based on a simple concept—that employees have both a need and a right to know the hazards and identities of the chemicals they are exposed to when working. They also need to know what protective measures are available to prevent adverse effects from occurring. OSHA designed the HCS to provide employees with the information they need to know.
  • The HCS standard’s common name is “Employee Right-to-Know”
purpose scope
Purpose & Scope
  • In order to ensure chemical safety in the workplace, information must be available about the identities and hazards of the chemicals. OSHA's Hazard Communication Standard (HCS) requires the development and dissemination of such information:
    • Chemical manufacturers and importers are required to evaluate the hazards of the chemicals they produce or import, and
    • Prepare labels and material safety data sheets (MSDSs) to convey the hazard information to their downstream customers.
    • All employers with hazardous chemicals in their workplaces must have labels and MSDSs for their exposed workers, and train them to handle the chemicals appropriately.

Ensure containers are labeled
  • Employees and contractors will be informed that they should check all incoming hazardous material container labels for the following information:
    • identity of product appropriate hazard warning
    • name and address of chemical manufacturer, importer, or other responsible party
  • Labels must be legible and prominently displayed. No existing label will be removed or defaced on containers of hazardous materials.
nfpa 704 hazard identification system
NFPA 704 Hazard Identification System
  • The National Fire Protection Agency (NFPA), in section 704 of the National Fire Code, specifies a system for identifying the hazards associated with materials. Although the system was developed primarily with the needs of fire protection agencies in mind, it is of value to anyone who needs to handle potentially hazardous material.
  • The hazard identification signal is a color-coded array of four numbers or letters arranged in a diamond shape. You will see hazard diamonds like this on trucks, storage tanks, bottles of chemicals, and in various other places. The blue, red, and yellow fields (health, flammability, and reactivity) all use a numbering scale ranging from 0 to 4. A value of zero means that the material poses essentially no hazard; a rating of four indicates extreme danger. The fourth value (associated with white) tends to be more variable, both in meaning and in what letters or numbers are written there.
hmig hazardous material identification guide hmis hazardous material information system
HMIG -- Hazardous Material Identification GuideHMIS -- Hazardous Material Information System
  • The OSHA Hazard Communication Standard (HCS) requires all chemicals in the workplace to be labeled in a manner that warns of any hazards the chemical may present. The actual format and method of labeling is not specified, so there are several different formats in use. The NFPA hazard diamond is one such method. Two other HCS compliance systems that are very similar to one another are described here.
  • The Hazardous Material Identification Guide (HMIG) is a labeling system developed and sold through Lab Safety Supply Inc. The Hazardous Material Information System (HMIS) is a labeling system developed by the National Paint and Coatings Association (NPCA) and sold through Labelmaster Inc. Both systems use a label with four color bars and a space at the top where the name of the chemical should be written (see figure this page). The blue, red, and yellow colored bars indicate, respectively, the health, flammability, and reactivity hazard associated with the material. These three bars use a numbering scale ranging from 0 to 4. A value of zero means that the material poses essentially no hazard; a rating of four indicates extreme danger. Although the details of how numbers are assigned may vary somewhat between systems, this is essentially the same overall scheme as is used in the NFPA system. (But see also the note on differences between NFPA and HMIG.) The fourth, white bar is marked "protective equipment" in the HMIG system, and "personal protection" in the HMIS system. Both systems (HMIG and HMIS) place a letter in this bar to indicate the kind(s) of personal protective equipment (PPE) that should be used in order to handle the material safely. The letters used are A - K and X. Meanings of the letters are the same in both systems, and both systems augment the letter code with icons or pictograms showing the kinds of PPE to be used.
  • A significant difference between the HMIG and HMIS systems is that the 1995 revised HMIS system includes a second box on the blue (health hazard) bar. If this second box holds an asterisk (*), then the health hazard associated with the material is a chronic (long-term) effect.
similarities and differences between nfpa and hmis
Similarities and Differences between NFPA and HMIS
  • Both the NFPA Hazard Identification System and the Hazardous Material Identification Guide (HMIG or HMIS) may be used to comply with the labeling requirement of the OSHA Hazard Communication Standard (HCS). These systems, although similar, differ in some important respects.
  • Similarities
    • Both systems have three color-coded fields to indicate the flammability (red), health (blue), and reactivity (yellow) hazards associated with the material.
    • Both use a system of five numbers, ranging from 0 to 4, to indicate the severity of hazard, with 0 being the least and 4 being the most hazardous.
  • Differences
    • They differ in layout -- NFPA uses four diamonds, HMIG uses vertically stacked bars.
    • The differ in interpretation of the fourth, white field (special handling in the NFPA system; protective equipment in the HMIG system).
    • Possibly the most significant difference, however, has to do with the intended audience for each of the systems. The HMIG (or HMIS) was devised as an HCS compliance tool, and has employees who must handle hazardous chemicals in the workplace as the intended audience. The NFPA system was designed to alert fire fighters arriving on the scene of a fire to the hazards associated with materials present at that location. Therefore, the numbers assigned in the NFPA system assume that a fire is present. No such assumption holds in the HMIG/HMIS system. For this reason, the numbers that are assigned to the flammability, health, and reactivity hazards may differ between the NFPA and HMIG systems, even for the exact same chemical.
nfpa and hmig labels
NFPA and HMIG Labels
  • NFPA and HMIG labels can be obtained, for example, from
    • http://www.labsafety.com/store/Signs_-_Labels_-_Tapes/Labels/RTK_-_Chemical_Labels/60373/ or
    • http://www.shippinglabels.com/RTK/chemical_labels.asp
  • or generated internally
write on hmig labels can be obtained from labsafety com
Write On HMIG Labels Can be Obtained from Labsafety.com

Use HMIG Write-On Labels to identify hazard ratings quickly and easily on containers in your workplace. Two sizes of self-adhesive paper Labels help you warn workers about dangers. Small Labels have room for you to write in the chemical name, manufacturer, date and rating. Large Labels allow you to add all the same information as the Small Labels plus room for the common name. Roll of 1000.

Understanding MSDS

for OSHA Hazard Communication and WHMIS Training

AEE Training Program

2008

understanding msds34
Understanding MSDS
  • The information provided in this presentation supplements Canadian WHMIS and the US Hazard Communication training
  • Typical MSDS is reviewed using acetone as an example
  • This detailed approach should be used when providing chemical-specific part of the training. Each MSDS for ALL products used by every employee should be reviewed and discussed in details
  • Emergency response planning for incidental exposure, including availability of FA/CPR trained personnel, first aid stations, eye wash stations, emergency showers, and proper storage and use requirements should be included as well as spill response planning
osha recommended format for material safety data sheets msdss
OSHA Recommended Format for Material Safety Data Sheets (MSDSs)
  • In 1985, US Occupational Safety & health Administration (OSHA) established a voluntary format for MSDSs (OSHA Form 174) to assist manufacturers and importers who desired guidance on organizing MSDS information.
  • When completed correctly, an MSDS prepared using Form 174 contains all of the information required by OSHA Hazard Communication Standard (29CFR1910.1200).
  • However, Form 174 does not use the more organized and comprehensive 16-section format.
    • …more from http://www.osha.gov/dsg/hazcom/msdsformat.html
minimum msds content form 174
Minimum MSDS Content – Form 174
  • Identity
  • Hazardous Ingredients
  • Physical/Chemical Characteristics
  • Fire and Explosion Hazard Data
  • Reactivity Data
  • Health Hazard Data
  • Precautions for Safe Handling and Use
  • Control Measures
ansi 16 section msds format
ANSI 16-section MSDS Format
  • OSHA believes that use of a consistent format will improve the effectiveness of MSDSs by making information easier for the reader to find, regardless of the supplier of the MSDS.
  • Because the 16-section format is accepted by consensus as the most appropriate format, OSHA no longer endorses that Form 174 be used for the preparation of MSDSs.
  • Use of Form 174, however, is still acceptable under the HCS if it is completed correctly.
ansi 16 section msds format42
ANSI 16-section MSDS Format
  • In order to promote consistent presentation of information, OSHA now recommends that MSDSs follow the 16-section format established by the American National Standards Institute (ANSI) standard for preparation of MSDSs (Z400.1).
  • By following this recommended format, the information of greatest concern to workers is featured at the beginning of the data sheet, including information on chemical composition and first aid measures.
  • More technical information that addresses topics such as the physical and chemical properties of the material and toxicological data appears later in the document.
  • While some of this information (such as ecological information) is not required by the OSHA Hazard Communication Standard (HCS), the 16-section MSDS is becoming the international norm.

section 3 hazards identification49
Section 3: Hazards Identification
  • Potential Health EffectsInhalation:Inhalation of vapors irritates the respiratory tract. May cause coughing, dizziness, dullness, and headache. Higher concentrations can produce central nervous system depression, narcosis, and unconsciousness. Ingestion:Swallowing small amounts is not likely to produce harmful effects. Ingestion of larger amounts may produce abdominal pain, nausea and vomiting. Aspiration into lungs can produce severe lung damage and is a medical emergency. Other symptoms are expected to parallel inhalation. Skin Contact:Irritating due to defatting action on skin. Causes redness, pain, drying and cracking of the skin. Eye Contact:Vapors are irritating to the eyes. Splashes may cause severe irritation, with stinging, tearing, redness and pain. Chronic Exposure:Prolonged or repeated skin contact may produce severe irritation or dermatitis. Aggravation of Pre-existing Conditions:Use of alcoholic beverages enhances toxic effects. Exposure may increase the toxic potential of chlorinated hydrocarbons, such as chloroform, trichloroethane.
section 4 first aid measures
Section 4: First Aid Measures
  • This section lists very basic first aid procedures for all routes of entry such as:
  • Inhalation:Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
  • Ingestion:Aspiration hazard. If swallowed, vomiting may occur spontaneously, but DO NOT INDUCE. If vomiting occurs, keep head below hips to prevent aspiration into lungs. Never give anything by mouth to an unconscious person. Call a physician immediately.
  • Skin Contact:Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
  • Eye Contact:Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Get medical attention.
section 5 fire fighting measures
Section 5: Fire Fighting Measures
  • Fire: Flash point: -20C (-4F) CCAutoignition temperature: 465C (869F)Flammable limits in air % by volume: LEL: 2.5; UEL: 12.8Extremely Flammable Liquid and Vapor! Vapor may cause flash fire.
  • Explosion: Above flash point, vapor-air mixtures are explosive within flammable limits noted above. Vapors can flow along surfaces to distant ignition source and flash back. Contact with strong oxidizers may cause fire. Sealed containers may rupture when heated. This material may produce a floating fire hazard. Sensitive to static discharge.
  • Fire Extinguishing Media: Dry chemical, alcohol foam or carbon dioxide. Water may be ineffective. Water spray may be used to keep fire exposed containers cool, dilute spills to nonflammable mixtures, protect personnel attempting to stop leak and disperse vapors.
  • Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
section 6 accidental release measures
Section 6: Accidental Release Measures
  • Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate container or absorb with an inert material (e. g., vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer! If a leak or spill has not ignited, use water spray to disperse the vapors, to protect personnel attempting to stop leak, and to flush spills away from exposures. US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the US Coast Guard National Response Center is (800) 424-8802.J. T. Baker SOLUSORB® solvent adsorbent is recommended for spills of this product.
section 7 handling and storage
Section 7: Handling and Storage
  • Protect against physical damage. Store in a cool, dry well-ventilated location, away from any area where the fire hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Containers should be bonded and grounded for transfers to avoid static sparks. Storage and use areas should be No Smoking areas. Use non-sparking type tools and equipment, including explosion proof ventilation. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.
section 8 exposure control and personal protection
Section 8: Exposure Control and Personal Protection
  • Airborne Exposure Limits:Acetone:OSHA Permissible Exposure Limit (PEL): 1000 ppm (TWA)ACGIH Threshold Limit Value (TLV): 500 ppm (TWA), 750 ppm (STEL) A4 - not classifiable as a human carcinogen
  • Ventilation System:A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
  • Personal Respirators (NIOSH Approved):If the exposure limit is exceeded and engineering controls are not feasible, a half-face organic vapor respirator may be worn for up to ten times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece organic vapor respirator may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
  • Skin Protection:Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
  • Eye Protection:Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.
section 8 understanding airborne exposure limits
Section 8: Understanding Airborne Exposure Limits
  • Airborne Exposure Limits:
    • Acetone:OSHA Permissible Exposure Limit (PEL): 1,000 ppm (TWA)ACGIH Threshold Limit Value (TLV): 500 ppm (TWA), 750 ppm (STEL) A4 - not classifiable as a human carcinogen
  • What is permissible exposure limit (PEL) and threshold limit value (TLV)?
    • OSHA PELs are based on the numbers developed by the American Conference of Governmental Industrial Hygienists (ACGIH) at the time when the OSHA standard 1910.1000 was finalized. These numbers are rarely updated. They are represent mandatory value to comply with in the US.
    • Current ACGIH TLV numbers (updated annually) represent the best management practice and standard of care. Accepted as a standard in some jurisdictions in the US, Canada and around the Globe.
    • Three categories of TLV are specified by the ACGIH:
    • Threshold Limit Value – Time Weighted Average (TLV – TWA)
    • Threshold Limit Value – Short Term Exposure Limit (STEL)
    • Threshold Limit Value – Ceiling (C)
section 8 understanding airborne exposure limits56
Section 8: Understanding Airborne Exposure Limits
  • Threshold Limit Value – Time Weighted Average (TLV – TWA)
    • The time weighted concentration for a normal 8-hour workday and a 40-hour workweek, to which nearly all workers may be repeatedly exposed, day after day, without adverse effect
  • Threshold Limit Value – Short Term Exposure Limit (STEL)
    • A STEL is defined as a 15-minute TWA exposure which should not be exceeded at any time during a workday. Exposures to STEL should be no longer than 15-minutes and no more than 4 times a day.
  • Threshold Limit Value – Ceiling (C)
    • The concentration that should not be exceeded during any part of working exposure
  • OSHA Permissible Exposure Limit utilizes similar but slightly different conditions
section 8 understanding airborne exposure limits57
Section 8: Understanding Airborne Exposure Limits
  • TLVs for gases and vapors are usually established in term of parts per million of substance in air by volume (ppm)
  • They also, sometimes, listed in term of milligrams of substance per cubic meter of air (mg/m3)
  • The conversion is based on 760 torr barometric pressure at 25oC (77oF, and where 24.45 = molar volume in liters, giving a conversion equation of:
  • TLV, mg/m3 = TLV, ppm * (gram molecular weight of substance)/24.45
  • TLV, ppm = TLV, mg/m3 * 24.45/ (gram molecular weight of substance)
section 8 understanding airborne exposure limits58
Section 8: Understanding Airborne Exposure Limits
  • Carcinogenicity
    • A1 – confirmed human carcinogen
    • A2 – suspected human carcinogen
    • A3 – animal carcinogen
    • A4 – not classifiable as human carcinogen
    • A5 – not suspected as human carcinogen

Section 15: Reading Regulatory Information
  • TSCA Inventory (US)
    • EPA classifies chemical substances as either "existing" chemicals or "new" chemicals. The only way to determine if the substance you are working with is a new chemical is by consulting EPA's Toxic Substances Control Act Chemical Substance Inventory (commonly referred to as the TSCA Inventory or just the Inventory). Any substance that is not on the Inventory is classified as a new chemical. If a substance is "new", it can be manufactured for a commercial purpose only if it is subject to an exemption from PMN reporting or a TSCA reporting exclusion (for example, a Low Volume Exemption, or exclusion as a naturally-occurring material). For substances which are "existing", the Inventory can be used to determine if there are restrictions on manufacture or use under the Toxic Substances Control Act (TSCA).There are approximately 75,000 chemical substances, as defined in Section 3 of the TSCA, on the Inventory at this time.
  • Canada DSL/NDSL Inventory
    • Canada's environmental inventory, the Domestic / Non-Domestic Substances List contains over 70,000 chemicals

Section 15: Reading Regulatory Information
  • SARA RQ, CERCLA RQ (US)
    • Any release of one or more of the roughly 800 CERCLA or 360 Emergency Planning and Community Right-to-Know Act (EPCRA or SARA Title III) hazardous substances that equals or exceeds a reportable quantity (RQ) must be reported to the EPA National Response Center (NRC) in the US.
    • RQs are adjusted to one of five levels: 1, 10, 100, 1,000, or 5,000 pounds. EPA bases adjustments to the RQs on the intrinsic characteristics of each hazardous substance, such as the aquatic toxicity, acute and chronic toxicity, ignitability, reactivity, and potential carcinogenicity. An RQ value is established for each of these characteristics of a hazardous substance, with the most stringent RQ value (i.e., the lowest quantity) becoming the final RQ or reporting trigger reporting for that hazardous substance spill or release.

Section 15: Reading Regulatory Information
  • What “RCRA 261.33 – U002” means? Acetone waste is classified as RCRA listed hazardous waste.
  • By definition, EPA determined that some specific wastes are hazardous. These wastes are incorporated into lists published by the Agency. These lists are organized into three categories:
  • The F-list (non-specific source wastes). This list identifies wastes from common manufacturing and industrial processes, such as solvents that have been used in cleaning or degreasing operations. Because the processes producing these wastes can occur in different sectors of industry, the F-listed wastes are known as wastes from non-specific sources. Wastes included on the F-list can be found in the regulations at 40 CFR §261.31.
  • The K-list (source-specific wastes). This list includes certain wastes from specific industries, such as petroleum refining or pesticide manufacturing. Certain sludges and wastewaters from treatment and production processes in these industries are examples of source-specific wastes. Wastes included on the K-list can be found in the regulations at 40 CFR §261.32.
  • The P-list and the U-list (discarded commercial chemical products). These lists include specific commercial chemical products in an unused form. Some pesticides and some pharmaceutical products become hazardous waste when discarded. Wastes included on the P- and U-lists can be found in the regulations at 40 CFR §261.33.
