1. Which federal regulation primarily governs hazardous materials
transportation in the United States?
A. OSHA 29 CFR 1910
B. NFPA 70
C. EPA RCRA Subtitle C
D. 49 CFR Parts 100–185
Answer: D. 49 CFR Parts 100–185
Rationale: Title 49 of the Code of Federal Regulations (CFR), Parts 100–
185, contains the Hazardous Materials Regulations (HMR), which
govern classification, packaging, marking, labeling, and transportation
of hazardous materials in commerce.
2. Which agency is responsible for enforcing workplace hazardous
materials safety standards?
A. FEMA
B. OSHA
C. DOT
D. NRC
Answer: B. OSHA
Rationale: The Occupational Safety and Health Administration (OSHA)
,enforces workplace safety regulations, including Hazard Communication
and HAZWOPER standards related to hazardous materials.
3. The primary purpose of the Emergency Response Guidebook
(ERG) is to:
A. Provide long-term remediation procedures
B. Identify responsible parties
C. Guide initial response actions during transportation incidents
D. Replace SDS documentation
Answer: C. Guide initial response actions during transportation
incidents
Rationale: The ERG assists first responders in identifying hazards and
establishing initial isolation and protective actions during the first 30
minutes of a hazardous materials transportation incident.
4. A material with a flash point below 73°F and boiling point below
100°F is classified as:
A. Combustible liquid
B. Class 3 flammable liquid (Packing Group I)
C. Oxidizer
D. Corrosive
Answer: B. Class 3 flammable liquid (Packing Group I)
Rationale: Liquids with low flash points and low boiling points present
higher fire hazards and fall under Packing Group I for flammable liquids.
5. The NFPA 704 diamond’s red quadrant indicates:
A. Health hazard
, B. Instability
C. Flammability
D. Special hazard
Answer: C. Flammability
Rationale: In NFPA 704, the red quadrant denotes flammability risk,
rated from 0 (minimal) to 4 (severe).
6. Which chemical is classified as a strong oxidizer?
A. Sodium chloride
B. Hydrogen peroxide (concentrated)
C. Methane
D. Nitrogen
Answer: B. Hydrogen peroxide (concentrated)
Rationale: Concentrated hydrogen peroxide releases oxygen readily,
intensifying combustion and qualifying as an oxidizer.
7. The term “IDLH” refers to:
A. Immediately Dangerous to Life or Health
B. Internal Departmental Laboratory Hazard
C. Industrial Daily Limit Hazard
D. Identified Dangerous Liquid Hazard
Answer: A. Immediately Dangerous to Life or Health
Rationale: IDLH values represent airborne concentrations that pose an
immediate threat to life or irreversible health effects or impair escape
ability.
, 8. Level A personal protective equipment provides:
A. Splash protection only
B. Structural firefighting protection
C. Maximum respiratory and skin protection
D. Respiratory protection without skin coverage
Answer: C. Maximum respiratory and skin protection
Rationale: Level A PPE includes a fully encapsulating suit with self-
contained breathing apparatus (SCBA), offering the highest level of
protection.
9. Which monitoring instrument detects oxygen concentration?
A. PID
B. FID
C. Combustible gas indicator
D. Oxygen meter
Answer: D. Oxygen meter
Rationale: An oxygen meter measures atmospheric oxygen levels to
detect deficiency (<19.5%) or enrichment (>23.5%).
10. A pH reading of 2 indicates a substance that is:
A. Neutral
B. Strongly acidic
C. Strongly basic
D. Non-corrosive
Answer: B. Strongly acidic
Rationale: A pH of 2 indicates high acidity, presenting corrosive hazards
to skin and materials.
