HAZMAT TECH I Questions and Answers
Technician Level Personnel/Hazardous Materials Technician
Ans: shall be that
person who responds to hazardous materials/WMD incidents using a
risk-based response process to analyze a problem involving hazardous
materials/WMD, plan a response to the problem, implement the planned
response, evaluate progress of the planned response and accordingly,
and assist in terminating the incident
Goals of Hazmat Technician (APIET)
Ans: - 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
Ans: microorganisms, such as viruses or bacteria (or their toxins), that
may cause severe, disabling disease or illness
Corrosives Hazards
Ans: - are materials that destroy living tissue and damage or destroy
metal
- Two categories: acids and bases
Explosivity

, 2 | Page
Ans: is any substance or article with a great deal of potential energy that
may rapidly expand and release upon activation (undergo an explosion)
Reactivity
Ans: describes its relative ability to undergo a chemical reaction with
itself or other materials
Radioactivity
Ans: - 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
Ans: Fuels susceptibility to ignition
Normal Atmospheric Conditions
Ans: 19.5%-23.5%
Oxygen Deficient
Ans: 19.5%
Oxygen Enriched
Ans: 23.5%
Thermal Hazard - Heat
Ans: •Hazardous material can cause temperature extremes.
•Fires, explosions involving flammable liquids, explosive materials can
cause burns
Thermal Hazard - Cold

Ans: •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
Ans: 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
Ans: True
Most gases ____ and _______ air
Ans: sink; displace
To properly determine concentrations of different gases, operate
monitoring and detection devices
Ans: - At different heights within a room/area
- At different grades within a building
Verify monitoring and sampling results when possible by using
Ans: - More than one sampling method
- More than one technology
When dealing with unknown materials or substances
Ans: Take an analytic approach in attempting to identify and
characterize hazards
Always assume _____ ______ ______ hazard is present
Ans: more than one
