Examination Overview
This comprehensive 150-question multiple-choice examination assesses competency in
Hazardous Materials First Responder Operations in accordance with current professional
standards including NFPA 470 (Hazardous Materials/Weapons of Mass Destruction
Standards for Responders), OSHA 29 CFR 1910.120 (HAZWOPER), and ICS/NIMS
principles.
The examination covers:
Recognition and identification of hazardous materials/WMD
Toxicology and health effects
Container recognition and behavior
Detection and monitoring
PPE and respiratory protection
Decontamination operations
Incident command and ICS
Defensive control tactics
Emergency response planning
Safety, risk assessment, and scene management
Evidence preservation and criminal/terrorism awareness
Legal and ethical responsibilities
Transportation regulations and placarding systems
Terrorism awareness and WMD response considerations
1.The primary responsibility of a Hazardous Materials First Responder at the
Operations level is to:
A. Perform offensive leak control
B. Conduct advanced chemical analysis
C. Protect people, environment, and property through defensive actions
D. Enter IDLH atmospheres to rescue victims
,Rationale: Operations-level responders take defensive actions without attempting
to stop the release directly.
2.Under OSHA 29 CFR 1910.120, the minimum training hours for
Operations-level responders is:
A. 8 hours
B. 24 hours
C. 40 hours
D. 80 hours
Rationale: HAZWOPER requires a minimum of 24 hours for operations-level
training.
3.The ERG guide number provides information primarily about:
A. Chemical manufacturing processes
B. Initial isolation and protective action distances
C. Detailed toxicology reports
D. Cleanup contractor contacts
Rationale: The Emergency Response Guidebook (ERG) provides initial response
guidance including isolation distances.
4.A material with a pH of 2 is classified as:
A. Neutral
B. Basic
C. Acidic
D. Oxidizing
Rationale: pH below 7 indicates acidity.
, 5.The diamond-shaped placard with a flame symbol and number 3 indicates:
A. Explosive
B. Flammable liquid
C. Radioactive material
D. Oxidizer
Rationale: Class 3 placards represent flammable liquids.
6.The MOST reliable method of hazardous material identification is:
A. Witness statements
B. Senses of smell
C. Container color
D. Shipping papers
Rationale: Shipping documents provide legally required identification.
7.A BLEVE is most commonly associated with:
A. Corrosive solids
B. Liquefied compressed gases
C. Radioactive isotopes
D. Biological agents
Rationale: Boiling Liquid Expanding Vapor Explosions occur in pressurized liquid
containers.
8.The recommended action for a chlorine railcar leak at Operations level is:
A. Patch the leak
B. Plug the rupture
, C. Establish isolation and deny entry
D. Neutralize with ammonia
Rationale: Defensive strategy includes isolation and scene control.
9.The primary purpose of decontamination is to: A.
Preserve evidence
B. Protect property
C. Prevent secondary contamination
D. Speed patient transport
Rationale: Decon prevents spread of contaminants.
10.The “hot zone” is best defined as the area:
A. Free from contamination
B. Where contamination is present or likely present
C. Used for staging
D. For media briefings
Rationale: The hot zone is the exclusion zone.
11.An IDLH atmosphere means:
A. Immediately Dangerous to Legal Health
B. Indirectly Dangerous to Life Hazard
C. Immediately Dangerous to Life or Health
D. Internal Dangerous Low Hazard
Rationale: IDLH indicates atmospheres posing immediate threat to life or
irreversible health effects.
