  1. Hazardous Materials Awareness Occupational Health and Safety Program

  2. Definition of Hazardous Material

  3. Training Requirement

  4. Hazard Identification

  5. Basic Clues to Recognition • Occupancy and location. • Container shape and size. • Placards and labels. • Material Safety Data Sheets • Markings and colors. • Human senses.

  6. Occupancy and Location • Specific occupancy or general area. • Fixed facilities. • Five modes of hazardous materials transportation: • Rail, air, marine, highway and pipeline. • Drug lab considerations.

  7. Container Shape and Size • Classifications • Portable, fixed or transportation. • Pressure • Non-pressurized, low or high pressure. • Vapor Pressure and Storage • The higher the pressure, the greater the potential for catastrophic failure: BLEVE!

  8. Placards and Labels • Placards and their limitations • Not always required. • Incorrect placard used. • Placards and labels used for transport are based upon DOT Hazard Class. • Nine Hazard Classes • Subdivided into divisions.

  9. Hazard Class 1 - Explosives Subdivided into 6 divisions 1.1 - Mass explosion hazard 1.2 - Projectile hazard 1.3 - Fire, minor blast or projectile 1.4 - Minor explosion 1.5 - Very insensitive explosives 1.6 - Extremely insensitive

  10. Hazard Class 2 - Gases • Pressurized or liquefied • Compressed nitrogen and liquefied petroleum gases (LPG) are examples. • Product and container present hazards. • Three Subdivisions • 2.1 - Flammable gases. • 2.2 - Non-Flammable, Non-Poisonous. • 2.3 - Poisonous Gases.

  11. Hazard Class 3 - Flammable/Combustible Liquids • Flammable Liquids can be ignited at room temperature. • Combustible Liquids require some degree of pre-heating to ignite. • Number 1 rule - eliminate ignition sources.

  12. Hazard Class 4 - Flammable Solids Three subdivisions 4.1 - Flammable Solids 4.2 - Spontaneously Combustible 4.3 - Dangerous when wet.

  13. Hazard Class 5 - Oxidizers and Organic Peroxides • Oxidizers release oxygen to enhance or intensify burn. • With strong fuels, oxidizers can create conditions which which can lead to violent combustion. • Many Organic Peroxides are very unstable.

  14. Hazard Class 6 - Poisonous and Infectious Substances • Poisonous to human • Can include severely irritating substances. • “Tear Gas”, Hydrocyanic acid, Carbon Tetrachloride. • Infectious Substances • Potential to cause diseases in humans. • Anthrax, human blood and many body fluids.

  15. Hazard Class 7 - Radioactive Materials • Ionizing radiation hazard. • Exposure does not always result in contamination. • Safety Rules • Time, Distance and Shielding. • Shipped in specialized containers.

  16. Hazard Class 8 - Corrosives

  17. Hazard Class 9 - Miscellaneous Hazardous Materials • ORM A - Dry Ice • ORM B - Quick Lime, Metallic mercury • ORM C - Asphalt, Battery parts • ORM D - Consumer commodities • ORM E - Hazardous substances and hazardous wastes

  18. Markings and Colors

  19. Material Safety Data Sheets (MSDS) • Required to be maintained by the Federal Hazard Communication Standard • Found at fixed facilities. • Provides a variety of information.

  20. Human Senses

  21. North American Emergency Response Guidebook • Goal • Purpose & Limitations

  22. Steps for Proper Use of the ERG • Recognize & Identify Hazardous Materials • Name • Four digit ID number • Placard description • Look up the guide page number. • Take basic protective actions according to the guide page. • Initiate isolation and evacuation according to protective action distances.

  23. Basic Protective Actions Main Objectives • Isolate • Protect by preventing contamination. • Follow Emergency Procedures. • Initiate your Emergency Plan.

  24. Protective Action Options • Shelter in-place • Short duration incidents. • Greater hazard to attempt to move. • Impractical to evacuate. • Evacuation • Potential for massive fire or explosion. • Long duration incidents.

  25. Thank You For Your Participation BE SAFE!
