1. The primary gas associated with fire deaths that are a product of incomplete
combustion is:
Carbon dioxide
Carbon monoxide
Carbon
PVC
2. Which NFPA standard defines the requirements for structural firefighting
boots?
NFPA 2001
NFPA 1300
NFPA 1971
NFPA 475
3. In a scenario where a fuel spill ignites a fire at a gas station, which type of
extinguisher would be most appropriate to use and why?
AFFF extinguisher, because it is designed for flammable liquid fires.
Dry chemical extinguisher, because it can handle all types of fires.
Water extinguisher, because it cools the flames.
CO2 extinguisher, because it suffocates the fire.
4. Describe the significance of personal protective equipment (PPE) in
firefighting as per NFPA standards.
, PPE is primarily used for aesthetic purposes in firefighting.
PPE is only necessary for wildland firefighting scenarios.
PPE is optional and only used in extreme conditions.
PPE is crucial for protecting firefighters from hazards and ensuring
their safety during fire incidents.
5. What is the name of the flame-resistant material commonly used in personal
protective equipment (PPE) for firefighters?
Polyester
Nylon
Cotton
Nomex
6. Describe the role of flame-resistant materials in the effectiveness of personal
protective equipment (PPE) for firefighters.
Flame-resistant materials are primarily for aesthetic purposes in
firefighting gear.
Flame-resistant materials are used to make PPE lighter for better
mobility.
Flame-resistant materials protect firefighters from heat and flames,
reducing the risk of burns.
Flame-resistant materials are only necessary in training scenarios, not
during actual fires.
7. If apparatus sirens and noise levels exceed decibels, firefighters
should wear hearing protection.
50-60
, 70-80
90
30-40
8. If a firefighter takes 90 seconds to don their PPE during an emergency, what
potential risks could arise from this delay?
Increased exposure to danger and reduced effectiveness in
responding to the fire.
Improved communication with the team.
Enhanced physical fitness due to the extra time taken.
No significant risks as time is flexible.
9. Which safety guideline will help minimize a firefighter's exposure to risk at a
structural fire scene?
Use apparatus lighting to fully illuminate the scene and surrounding
area
Report directly to the officer in command of the incident
Maintain communication with team members and Command
Divide labor into smaller, more manageable tasks in order to equalize
the workload
10. During a fire incident with sirens exceeding 90 Decibels, a firefighter is
unable to hear a critical communication from the command center. What
safety protocol could have prevented this situation?
Increasing the volume of the command center's radio.
Wearing appropriate hearing protection.
Using visual signals for communication.
, Reducing the number of firefighters on the scene.
11. Describe why an atmosphere with less than 19.5% oxygen is considered
hazardous for firefighters.
An atmosphere with less than 19.5% oxygen is safe for short durations.
An atmosphere with less than 19.5% oxygen has no impact on
firefighter performance.
An atmosphere with less than 19.5% oxygen can impair cognitive
and physical functions, posing serious risks to firefighters' safety.
An atmosphere with less than 19.5% oxygen is only dangerous for non-
firefighters.
12. What type of sprinkler system is used when there is a potential for freezing
temperatures to affect the system?
air-pressure
heated
dry-pipe
deluge
13. In a scenario where a chemical leak occurs during a fire, what immediate
action should firefighters take to ensure effective leak control?
Evacuate all personnel from the site immediately.
Ignore the leak and focus on extinguishing the fire.
Establish a containment area around the leak.
Use water to dilute the chemical.
