1. The primary responsibility of a Hazardous Materials Technician is to:
a) Perform initial size-up
b) Command incident operations
c) Stop the release through containment or confinement
d) Transport hazardous materials
Rationale: Technicians are trained to aggressively approach and control the
release using specialized skills.
2. The level of protection required when entering an unknown hazardous
atmosphere is:
a) Level C
b) Level A
c) Level B
d) Structural firefighting gear
Rationale: Level A provides the highest level of respiratory and skin
protection for unknown environments.
,3. The OSHA regulation that governs Hazardous Waste Operations and
Emergency Response (HAZWOPER) is:
a) 29 CFR 1910.1200
b) 49 CFR 172
c) 29 CFR 1910.120
d) NFPA 472
Rationale: OSHA 29 CFR 1910.120 defines training and safety requirements
for hazardous materials response.
4. A chlorine cylinder is leaking from its valve. The technician should first:
a) Push the cylinder into water
b) Apply the appropriate Chlorine Kit (A, B, or C kit)
c) Vent it to the atmosphere
d) Patch with duct tape
Rationale: Chlorine kits are specifically designed for containing leaks in
chlorine cylinders and tank cars.
5. Which detection device is best for identifying an unknown flammable gas?
a) Colorimetric tubes
b) Radiation detector
c) Combustible gas indicator (CGI)
d) Dosimeter
Rationale: CGIs measure the concentration of flammable vapors and gases
in air relative to their LEL.
6. What is the purpose of a HEPA filter in hazmat response?
a) Chemical absorption
, b) Capture particulates, including biological hazards
c) Neutralize corrosives
d) Detect oxygen levels
Rationale: HEPA filters trap microscopic particles, useful in biological and
particulate contamination scenarios.
7. The Incident Commander has identified a flammable liquid spill. The
technician’s priority is:
a) Public notification
b) Contain the spill and prevent ignition sources
c) Establish evacuation routes
d) Documentation
Rationale: Technicians work directly to stop releases and minimize risk of
ignition with flammable materials.
8. The “hot zone” in a hazmat incident is defined as:
a) Public information area
b) Safe refuge area
c) Area of direct contamination
d) Support staging area
Rationale: The hot zone is where contamination exists and only fully
protected responders may enter.
9. Which type of radiation requires the greatest shielding?
a) Alpha
b) Beta
c) Gamma
, d) Neutron
Rationale: Gamma radiation penetrates most materials, requiring dense
shielding like lead or concrete.
10.A technician using a photoionization detector (PID) is primarily measuring:
a) Oxygen concentration
b) Radiation levels
c) Volatile organic compounds (VOCs)
d) Temperature
Rationale: PIDs detect VOCs by ionizing molecules with UV light and
measuring the current produced.
11.The maximum safe working concentration of a toxic substance over an 8-
hour workday is known as:
a) IDLH
b) PEL (Permissible Exposure Limit)
c) TLV-C
d) REL
Rationale: PEL is OSHA’s regulatory limit for safe exposure over a standard
work shift.
12.The type of decontamination that removes most contaminants quickly
without full processing is called:
a) Mass decon
b) Emergency decon
c) Gross decon
