HAZ MAT AWARENESS AND OPS
NFPA 470 STUDY QUESTIONS WITH
CORRECT ANSWERS GRADED A+
FOR 2026 ASSURED EXCEL!!
1. Explain the differences between
a. National Institute for Occupational Safety and Health (NIOSH)
b. Occupational Safety and Health (OSHA)
c. National Fire Protection Association (NFPA)
d. Environmental Protection Agency (EPA) - CORRECT ANSWERS-OSHA and EPA
both put out regulations and they are governmental entities, Then NFPA and
NIOSH both put out standards and are non-governmental entities.
2. Describe the recovery phase - CORRECT ANSWERS-The recovery phase of a hazardous
materials incident occurs when the imminent danger to people, property, and the
environment has passed or is controlled and clean up begins. During this phase local,
state, and federal agencies may be involved in cleaning up site, determining the
responsible party, and implementing cost-recovery.
3. Describe how a Haz Mat scene should be approached - CORRECT ANSWERS-uphill and
upwind
4. Pryolysis - CORRECT ANSWERS-A process during which material is decomposed, or
broken down, into simpler molecular compounds by the effects of heat alone and the
often precedes combustion
5. doffing - CORRECT ANSWERS-The process of taking off an ensemble of PPE
6. donning - CORRECT ANSWERS-The process of putting on an ensemble of PPE
, 7. Weapons of Mass destruction (WMD) - CORRECT ANSWERS-any weapon or material
that is designed to cause death or serious injury or damage to buildings, structures, or
the environment. ex) explosive or incendiary bomb, rocket, or grenade containing or
delivering a toxic or dangerous chemical, biological agent, toxin, or vectors
8. penetration - CORRECT ANSWERS-the movement of material through a suit's closures,
such as zippers, ********s, seams, flaps, or other design features of chemical protective
clothing and through punctures, cuts, and tears
9. permeation - CORRECT ANSWERS-the chemical action involving the movement of
chemicals, on a molecular level through intact material
10. degradation - CORRECT ANSWERS-a chemical action involving the molecular breakdown
of protective clothing material or equipment due to contact with a chemical
11. flash point - CORRECT ANSWERS-the min temperature at which a liquid or solid gives off
sufficient vapors such that, when an ignition sources is present, the vapors will ignite,
resulting in a flash fire
12. fire point - CORRECT ANSWERS-the lowest temperature at which a liquid will ignite and
achieve sustained burning when exposed to a test flame in accordance with ASTM D 92
13. vaporzation - CORRECT ANSWERS-the process of a solid or liquid changing to a gas
14. polymerization - CORRECT ANSWERS-the process of reacting monomers together in a
chain reaction to form polymers
15. Explain Awareness level - CORRECT ANSWERS-The people that are acting normal duties,
and are to recognize hazardous materials and Weapons of Mass Destruction, and call for
trained personnel, and secure the area
