F-02 Hazardous Materials Awareness Practice Test 1 — Questions and Answers
Question 1: What is considered a hazardous material in the context of shelter fire safety?
- Only radioactive materials
- Any substance that poses a threat to health, safety, or property when released or mishandled (Correct answer)
- Only materials that are currently on fire
- Hazardous materials are not found in shelters
Correct answer: Any substance that poses a threat to health, safety, or property when released or mishandled
A hazardous material is any substance that can cause harm to people, property, or the environment when released or improperly handled. In shelters, this includes cleaning chemicals, flammable liquids, compressed gas cylinders, pesticides, and other commonly found substances.
Question 2: What does the NFPA 704 diamond placard indicate?
- The building's fire insurance rating
- The type, severity, and special hazards of materials stored in a location (Correct answer)
- The building's age and construction type
- The number of fire exits
Correct answer: The type, severity, and special hazards of materials stored in a location
The NFPA 704 diamond (fire diamond) is a hazard identification system using a four-colored diamond to indicate health hazards (blue), flammability (red), instability/reactivity (yellow), and special hazards (white). Numbers 0-4 indicate severity levels from minimal to severe.
Question 3: What color on the NFPA 704 diamond indicates flammability hazard?
- Blue
- Yellow
- White
- Red (Correct answer)
Correct answer: Red
Red is the color for flammability hazard on the NFPA 704 diamond, located at the top of the diamond. A rating of 0 means the material will not burn, while a rating of 4 means it will rapidly vaporize and burn readily at normal temperatures.
Question 4: What is the Fireguard's primary role when a hazardous material spill occurs in a shelter?
- Clean up the spill immediately
- Evacuate the area, prevent others from entering, call 911, and report the spill to building management (Correct answer)
- Identify the chemical and neutralize it
- Continue normal patrol and note it in the log
Correct answer: Evacuate the area, prevent others from entering, call 911, and report the spill to building management
The Fireguard is at the 'awareness' level for hazardous materials, meaning their role is to recognize a hazmat situation, protect themselves and others by evacuating and isolating the area, call for professional help (911), and report to building management. They should NOT attempt cleanup.
Question 5: What is a Safety Data Sheet (SDS) and where should it be located?
- A building permit document stored at city hall
- A document describing chemical hazards, safe handling, and emergency procedures, kept accessible to workers (Correct answer)
- A sheet listing the building's safety features
- An insurance document listing covered materials
Correct answer: A document describing chemical hazards, safe handling, and emergency procedures, kept accessible to workers
A Safety Data Sheet (formerly MSDS) contains detailed information about a chemical product including its hazards, safe handling procedures, storage requirements, first aid measures, and emergency response procedures. SDSs must be readily accessible to all workers who may be exposed to the chemicals.
Question 6: Which common shelter cleaning product can produce toxic chlorine gas when mixed with ammonia?
- Glass cleaner
- Bleach (sodium hypochlorite) (Correct answer)
- Dish soap
- Floor wax
Correct answer: Bleach (sodium hypochlorite)
Bleach (sodium hypochlorite) mixed with ammonia or ammonia-containing cleaners produces toxic chlorine gas and chloramine vapors. This is a common and dangerous accidental chemical reaction in buildings where different cleaning products are used in the same area.
