COMPREHENSIVE QUESTIONS AND ANSWERS - CURRENT
VERSION 2026/2027
1. What is the fire triangle?
The fire triangle consists of three elements necessary for fire: heat (ignition
source), fuel (combustible material), and oxygen. Removing any one element
extinguishes the fire.
2. What is the fire tetrahedron?
The fire tetrahedron adds a fourth element to the fire triangle — the chemical
chain reaction. It represents the self-sustaining chain reaction that keeps a fire
burning. Disrupting the chain reaction (e.g., with halon or clean agents)
extinguishes the fire.
3. Define 'flashover' in fire behavior.
Flashover is the near-simultaneous ignition of most of the directly exposed
combustible material in an enclosed area. It marks the transition from a
growing fire to a fully developed fire, usually occurring when temperatures
reach approximately 500–600°C (932–1112°F).
4. What is a backdraft?
A backdraft is an explosive event caused by the sudden introduction of
oxygen to a fire that has depleted available oxygen in an enclosed space.
Signs include smoke-stained windows, puffing smoke, and hot doors.
5. What are the four stages of fire development?
The four stages are: (1) Incipient/Ignition stage, (2) Growth stage, (3) Fully
developed stage, and (4) Decay/Smoldering stage.
6. What is the flash point of a liquid?
The flash point is the lowest temperature at which a liquid produces sufficient
vapor to ignite momentarily when an ignition source is applied. Liquids with
lower flash points are more flammable.
7. What is the difference between flammable and combustible liquids?
Page 1 of 39
, Flammable liquids have a flash point below 37.8°C (100°F). Combustible
liquids have a flash point at or above 37.8°C (100°F) but below 93.3°C
(200°F). Flammable liquids pose a greater fire risk at normal temperatures.
8. What is the Lower Explosive Limit (LEL)?
The LEL is the minimum concentration of a flammable gas or vapor in air
below which a flame will not propagate. Below the LEL, the mixture is too lean
to ignite.
9. What is the Upper Explosive Limit (UEL)?
The UEL is the maximum concentration of a flammable gas or vapor in air
above which a flame will not propagate. Above the UEL, the mixture is too rich
(insufficient oxygen) to ignite.
10. What is the auto-ignition temperature?
Auto-ignition temperature is the minimum temperature at which a substance
will spontaneously ignite without an external ignition source. It is important for
assessing fire risks in hot work environments.
11. Name the classes of fire.
Class A: Ordinary combustibles (wood, paper, cloth). Class B: Flammable
liquids and gases. Class C: Energized electrical equipment. Class D:
Combustible metals. Class K: Cooking oils and fats.
12. What extinguishing agent is used for Class D fires?
Class D fires (combustible metals like magnesium, titanium, sodium) require
dry powder extinguishing agents specifically designed for the metal involved
(e.g., dry sand, dry graphite, Met-L-X powder). Water must never be used.
13. What is a Class K fire extinguisher used for?
Class K fire extinguishers use wet chemical agents (typically potassium
acetate) and are designed for cooking fires involving vegetable oils, animal
fats, or grease in commercial cooking equipment.
14. Explain the PASS technique for using a fire extinguisher.
PASS stands for: Pull the pin, Aim the nozzle at the base of the fire, Squeeze
the handle, and Sweep side to side at the base of the fire.
15. What is a fire load?
Fire load (also called fuel load) is the total amount of combustible material in a
given area, expressed in kg/m² or BTU/ft². It is used to assess the potential
severity of a fire in a compartment.
16. What is a fire risk assessment?
Page 2 of 39
, A fire risk assessment is a systematic evaluation of premises to identify fire
hazards, assess the risk to people and property, evaluate existing fire safety
measures, and determine additional measures needed to reduce risk to an
acceptable level.
17. What are the five steps of a fire risk assessment?
1) Identify fire hazards; 2) Identify people at risk; 3) Evaluate, remove, reduce,
and protect from risk; 4) Record, plan, instruct, inform, and train; 5) Review
and update the assessment regularly.
18. What is the purpose of a fire safety management plan?
A fire safety management plan documents fire safety policies, procedures,
responsibilities, and systems for a facility. It ensures systematic management
of fire risks, compliance with regulations, and preparedness for emergencies.
19. What is meant by 'means of escape'?
Means of escape refers to the structural means by which a safe route is
provided from any point in a building to a place of safety. It includes corridors,
stairways, emergency exits, and assembly areas.
20. What is a place of safety in fire safety terminology?
A place of safety is a location where persons are no longer in danger from fire.
It may be a final exit from a building to an open space or a protected area
where people can safely await rescue or evacuation.
21. Define 'fire compartmentation'.
Fire compartmentation is the division of a building into sections using fire-
resistant construction (walls, floors, doors) to contain a fire and limit its spread,
providing time for evacuation and firefighting.
22. What is a fire door?
A fire door is a fire-resistant door assembly designed to prevent the spread of
fire and smoke between compartments of a building. It must be self-closing
and latch securely when closed.
23. What is the minimum fire resistance rating required for most fire doors?
Common fire door ratings include FD30 (30 minutes) and FD60 (60 minutes).
The required rating depends on the building type, location, and applicable fire
codes. FD30 is common for escape routes.
24. What is a passive fire protection system?
Passive fire protection (PFP) uses structural elements (fire-rated walls, floors,
doors, intumescent seals) to contain or slow fire and smoke spread without
active mechanical operation.
Page 3 of 39
, 25. What is an active fire protection system?
Active fire protection (AFP) requires action or motion to work — either
automated (sprinklers, fire alarms) or manual (extinguishers). AFP systems
actively detect, suppress, or alert occupants to fire.
26. What is an intumescent seal?
An intumescent seal is a fire-stopping material that expands significantly when
exposed to heat, filling gaps around pipes, cables, or door frames to prevent
fire and smoke from spreading through compartment boundaries.
27. What causes most fire-related deaths?
Most fire-related deaths are caused by smoke inhalation rather than direct
flame contact. Toxic gases such as carbon monoxide, hydrogen cyanide, and
lack of oxygen cause incapacitation before the victim can escape.
28. What is a fire escape plan?
A fire escape plan is a documented strategy outlining evacuation procedures,
escape routes, assembly points, designated responsibilities (fire wardens),
and protocols for accounting for all occupants during a fire emergency.
29. How often should fire drills be conducted?
Most fire codes and standards require fire drills at least once or twice per year,
depending on occupancy type. High-risk occupancies (hospitals, schools) may
require more frequent drills.
30. What is a fire assembly point?
A fire assembly point (muster station) is a designated safe location outside a
building where evacuated occupants gather so that a roll call or headcount
can be performed to account for all personnel.
SECTION 2: Fire Safety Regulations & Standards
31. What is NFPA and what is its role?
NFPA (National Fire Protection Association) is a non-profit organization that
creates and maintains fire safety codes and standards, including NFPA 1 (Fire
Code), NFPA 13 (Sprinklers), and NFPA 72 (Fire Alarm). These standards are
widely adopted globally.
32. What does NFPA 101 cover?
NFPA 101 (Life Safety Code) covers construction, protection, and occupancy
requirements to minimize danger to life from fire, smoke, fumes, or panic. It
addresses means of escape, emergency lighting, and occupancy-specific
requirements.
