Presentation Transcript

  1. HAZARDOUS WASTE OPERATIONS AND EMERGENCY RESPONSE - AWARENESS 29 CFR 1910.120 Revised July 2000

  2. Objectives • Define your role at the Awareness level? • “Clues” to be gathered upon discovering an incident. • Be able to read placards and labels. • Able to read and interpret the DOT book. • Able to implement site security and control. • Understand the basics of an Emergency Response Plan

  3. Role of First Responder - Awareness 29 CFR 1910.120(q) • Likely to witness or discover release. • Trained to initiate emergency response. • Take no further action .

  4. FIRST RESPONDER AWARENESS LEVEL • Understand what hazardous materials are and their risks in an incident. • Understand the potential outcome of an emergency created when hazardous materials are present. • Ability to recognize the presence of hazardous materials in an emergency.

  5. Ability to identify hazardous materials if possible • Role of the First Responder in the Emergency Response Plan including site security & control and DOT’s Emergency Response Guidebook. • Ability to realize the need for additional resources and to make appropriate notification to communication center.

  6. HISTORY • Superfund Amendments and Reauthorization Act of 1986 (SARA) • allocated funds to develop health and safety training for workers involved in transportation, storage, or disposal of hazardous waste.

  7. Hazard Recognition Definitions Hazardous substance: “OSHA” Hazardous waste: “EPA” Hazardous material: “DOT”

  8. Hazardous Substance - OSHA • A substance which may result in adverse affects on the health and safety of employees • A substance included as a hazardous material by DOT and as a hazardous waste by EPA

  9. Hazardous Waste - EPA Poses unreasonable risk to health, safety or property when transported in commerce for the purposes of treatment, storage, or disposal as waste

  10. Hazardous Material - DOT Any substance or material in any form or quantity which poses an unreasonable risk to safety and health and property when transported in commerce

  11. Chemical Hazards • Flammable • Corrosive • Reactive • Toxic • Sudden Release of Pressure (explosion) • detonation and deflagration

  12. Physical Hazards to Employees • Radiation • Electricity • Stress • Heat/Cold • Slips, trips, falls • Steam & Chemical clouds

  13. Biological Hazards • Infectious Hospital Waste • Research Materials • Raw sewage (hepatitis A, E-coli) • Bites from vectors (ticks, rats, wild dogs)

  14. Mode Inhalation Ingestion Injection Absorption Route Respiratory System Gastrointestinal Sys. Skin Skin Modes and Routes of Entry

  15. Health Effects • Acute • body response at time of exposure, typically a high concentration, or a few days after exposure. • Chronic • body response takes a long time after repeated or prolonged exposures.

  16. PPM TLV PEL REL TWA C STEL IDLH OSHA ACGIH NIOSH Definitions

  17. Inhalation Hazard? Handy rules of thumb • vapor pressure • <10 mmHg slow • 10-50 mmHg medium • >50 mmHg fast • evaporation rate • <0.8 slow • 0.8 - 3 medium • > 3 fast

  18. Target Organs • Nephrotoxin - kidneys • Hepatotoxin - liver • Neurotoxin - CNS • Hemotoxin - blood • Mutagenic - genetic material • Teratogenic - fetal deformities • Carcinogenic - cancer causing

  19. Factors of Toxicity • Time & Frequency (TWA, STEL) • Route by which exposure occurs • Physical & chemical form of the substance • Dose delivered

  20. Fire & Explosion Characteristics • Components of Combustion Fuel Oxidizer Ignition Sources

  21. Fire & Explosive CharacteristicsSources of Ignition Cigarettes Welding Grinding / Cutting Unprotected electrical equipment Open flames Hot surfaces Static electricity Oxidizing chemicals

  22. Class A Class B Class C Class D Classes Of Fires

  23. Class A/Ordinary Combustible -Extinguish with water • Class B/Flammable Liquids. Use a Dry Chemical Extinguisher • Class C/Electrical Equipment. Use a CO2 Extinguisher • Class D/Combustible Metals. Use a Dry Powder Extinguisher

  24. Flash Point Ignition Auto Ignition Lower Flammability Limit Upper Flammability Limit Combustible Flammability Range Oxidizers Terminology: Flammable

  25. Flammable vs. Combustible • Flammable • A liquid with a flash point below 100oF (Source: 29 CFR 1910.106) • A liquid with a flash point below 141oF (Source: DOT)

  26. Combustible • A liquid with a flash point at or above 100oF but below 200oF (Source: 29 CFR 1910.106) • A liquid with a flash point at or above 141oF but below 200oF (Source: DOT)

  27. Hazard Identification • Labels and Placards • Other Documentation (MSDS) • Container Shape

  28. Labels and Placards • DOT System • NFPA System • HMIS System COR 1831

  29. DOT System • Shipping papers • Markings • Labeling • Placarding

  30. Shipping Papers • Proper shipping name • Hazard class (9 classes) • Identification number • Packing group • Container type • Quantity • Shipper data • Emergency phone number

  31. Markings • Proper shipping name • Identification number • Address of the shipper

  32. Labels & Placards • Graphic representation of the hazard • Labels on packaging/containers • Placards on the outside - ends & sides of trucks, rail cars, freight containers

  33. NFPA SYSTEM • Diamond-shaped • Color-coded in 4 small diamonds • Blue Health risk • Red Flammability • Yellow Reactivity • White Special information • Number-coded in the red, blue, and yellow diamonds

  34. Chemical Name Health Hazard Fire Hazard Flash Points 4-Below 73 F 3-Below 100 F 2-Below 200 F 1-Above 200 F 0-Will not burn 4-Deadly 3-Extremely Hazardous 2-Hazardous 1-Slightly Hazardous 0-Normal material Specific Hazard Reactivity 4-May detonate 3-Shock and heat may detonate 2-Violent chemical change 1-Unstable if heated 0-Stable Oxidizer OX Use NO WATER W

  35. HMIS Hazard Materials Identification System • Rectangular • Color-coded • Blue Health risk • Red Flammability • Yellow Reactivity • White Special information/PPE

  36. Hazard Materials Information Sheet Health Flammability Reactivity PPE

  37. NFPA vs. HMIS • NFPA is geared for fire emergencies • HMIS is geared for everyday use • NFPA and HMIS numbers are often in conflict (especially health and reactivity) • HMIS includes necessary PPE • NFPA includes special hazards

  38. Other Documentation • MSDS • Shipping Containers • Shipping Papers (Bill of Lading)

  39. How hazardous is it?? • Percent by weight • How volatile it is (vapor pressure) • Lowest exposure limit • Physical form • Route of entry • Chronic vs. acute • Where is it? (out in open, confined area)
