Answer: C - Placarding requirements generally apply to bulk shipments exceeding 1001 lbs.
4. The NFPA 704 Diamond indicates "Health" with which color?
A. Red
B. Blue
C. Yellow
D. White
Answer: B - Blue indicates health hazard, Red indicates flammability, Yellow indicates instability,
and White indicates special hazards.
,5. In the NFPA 704 system, what does a "4" in the blue section indicate?
A. Material that is slightly hazardous
B. Material that is extremely hazardous
C. Material that is unstable at high temperatures
D. Material that will not burn
Answer: B - A rating of "4" in any section indicates the highest level of hazard. A "4" in health
means the material can be lethal.
6. A substance with a flashpoint below 100°F (37.8°C) is considered:
A. Combustible
B. Flammable
C. Explosive
D. Corrosive
Answer: B - Flammable liquids have a flashpoint below 100°F, while combustible liquids have a
flashpoint at or above 100°F.
7. Which of the following is an example of a chemical weapon agent?
A. Chlorine
B. Anthrax
C. VX nerve agent
D. Asbestos
Answer: C - VX is a manufactured nerve agent designed for chemical warfare. Chlorine is a toxic
industrial chemical that can be weaponized but is not exclusively a weapon agent.
8. The "S" in the acronym CBRNE stands for:
A. Safety
B. Systemic
C. Secondary
D. Security
Answer: C - CBRNE stands for Chemical, Biological, Radiological, Nuclear, and Explosives.
9. The process of a solid changing directly to a gas without first becoming a liquid is called:
A. Evaporation
B. Condensation
C. Sublimation
D. Vaporization
Answer: C - Sublimation is a common characteristic of materials like dry ice (solid CO2).

A. React violently with water
,B. Cause metals to corrode
C. Readily donate electrons to other substances
D. Readily accept electrons from other substances (fueling a fire)
Answer: D - Oxidizers provide oxygen or other electron-accepting substances, which can greatly
intensify a fire.
11. The primary purpose of the Emergency Response Guidebook (ERG) is to:
A. Provide long-term cleanup procedures
B. Provide initial guidance for first responders in emergencies
C. Replace formal hazardous materials training
D. Diagnose chemical exposure symptoms
Answer: B - The ERG is designed for the initial, short-term response phase.
12. You arrive at a scene and see a placard with the UN number 1072. What is your first step
using the ERG?
A. Look in the Yellow-bordered section
B. Look in the Blue-bordered section
C. Look in the Orange-bordered section
D. Look in the Green-bordered section
Answer: A - The Yellow-bordered section is for ID number (UN/NA) index.
13. In the ERG, the Orange-bordered pages provide:
A. Isolation and protective action distances
B. Fire and explosion hazards
C. Initial isolation and protective action distances
D. Response guides with safety recommendations
Answer: D - The Orange Guides provide the critical safety advice for the incident.
14. If you identify a material by its name (e.g., "Chlorine"), which section of the ERG should
you use first?
A. Yellow-bordered
B. Blue-bordered
C. Orange-bordered
D. Green-bordered
Answer: B - The Blue-bordered section is the alphabetical list of hazardous materials.
15. The ERG recommends an initial isolation distance in all directions of 200 feet for a small
spill of an unknown material from a tank truck. This initial isolation zone is found in the:
A. Orange Guide
B. Green-bordered section
, C. Table of Initial Isolation and Protective Action Distances
D. First page of the Yellow-bordered section
Answer: A - The initial isolation distance is prominently displayed at the top of each Orange
Guide.
16. The Table of Initial Isolation and Protective Action Distances (Green-bordered section) is
used for:
A. All hazardous materials incidents
B. Only flammable gas incidents
C. Materials that are TIH (Toxic Inhalation Hazards)
D. Only radioactive materials
Answer: C - The green table is specifically for materials that are Toxic by Inhalation (TIH), which
present a severe vapor cloud hazard.
17. A "P" next to a guide in the ERG indicates:
A. Polymerization hazard
B. Personal Protective Equipment required
C. Potentially explosive
D. Public safety threat
Answer: A - The "P" highlights a material's potential to undergo a dangerous polymerization
reaction.
18. The recommended initial isolation distance for a TIH gas incident is primarily based on:
A. The size of the container
B. The time of day
C. The wind speed and day/night condition
D. The type of emergency vehicle on scene
Answer: A - The initial isolation distance is a fixed, immediate buffer zone. The larger protective
action distances in the green table are based on the size of the spill and day/night conditions.
19. A substance with a pH of 2 is considered:
A. A strong base
B. A weak acid
C. A strong acid
D. Neutral
Answer: C - The pH scale runs from 0 (strong acid) to 14 (strong base), with 7 being neutral.
