HAZMAT TECH I COURSE FINAL 2026 TEST
QUESTIONS AND DETAILED SOLUTIONS
◉ Goals of Hazmat Technician (APIET). Answer: - Analyze a hazardous
material/WMD incident to identify the complexity of the problem and
potential outcomes
- Plan a response within the capabilities of available personnel, PPE, and
equipment
- Implement the planned response
- Evaluate the effectiveness of the response
- Terminate the incident
◉ Biological (Etiological) Hazards. Answer: microorganisms, such as
viruses or bacteria (or their toxins), that may cause severe, disabling
disease or illness
◉ Corrosives Hazards. Answer: - are materials that destroy living tissue
and damage or destroy metal
- Two categories: acids and bases
◉ Explosivity. Answer: is any substance or article with a great deal of
potential energy that may rapidly expand and release upon activation
(undergo an explosion)
,◉ Reactivity. Answer: describes its relative ability to undergo a
chemical reaction with itself or other materials
◉ Radioactivity. Answer: - The least energetic form of radiation is
nonionizing radiation such as visible light and radio waves.
- The most energetic (and hazardous) form of radiation is ionizing
radiation
◉ Flammability. Answer: Fuels susceptibility to ignition
◉ Normal Atmospheric Conditions. Answer: 19.5%-23.5%
◉ Oxygen Deficient. Answer: 19.5%
◉ Oxygen Enriched. Answer: 23.5%
◉ Thermal Hazard - Heat. Answer: •Hazardous material can cause
temperature extremes.
•Fires, explosions involving flammable liquids, explosive materials can
cause burns
,◉ Thermal Hazard - Cold. Answer: •Lack of heat can also cause harm;
cryogenic liquids, liquefied gases are so cold that if contacted, they can
cause damage, injuries.
•Cold atmospheric temperatures can complicate many hazmat operations
◉ Toxicity. Answer: Chemicals or biological substances that cause
sickness, illness, or injury by doing damage on the molecular scale when
in contact with the body
◉ T/F: The state of matter of the material being sampled will affect the
monitoring and detection techniques and devices used. Answer: True
◉ Most gases ____ and _______ air. Answer: sink; displace
◉ To properly determine concentrations of different gases, operate
monitoring and detection devices. Answer: - At different heights within a
room/area
- At different grades within a building
◉ Verify monitoring and sampling results when possible by using.
Answer: - More than one sampling method
- More than one technology
, ◉ When dealing with unknown materials or substances. Answer: Take
an analytic approach in attempting to identify and characterize hazards
◉ Always assume _____ ______ ______ hazard is present. Answer:
more than one
◉ Hazardous Solids. Answer: - Will usually not travel far unless blown
by wind or dispersed by explosion
- Responders at hazmat incidents involving hazardous solids will
typically be sufficiently protected when using firefighter protective
equipment with SCBA or level C PPE
◉ Hazardous Liquids may:. Answer: - Vaporize
- Expand rapidly
- Potentially travel great distances
- Fill low-level and confined spaces
◉ Hazardous gases. Answer: Can expand rapidly, fill enclosed spaces,
and may travel great distances from their source
◉ Corrosive gases can:. Answer: damage and penetrate firefighter
protective clothing and SCBA
