Fire Safety Fire Prevention and Hazard Identification 2 — Questions and Answers
Question 1: Which household item poses the greatest fire risk if left unattended while lit?
- A microwave oven
- An open flame candle (Correct answer)
- A slow cooker on low heat
- A laptop computer charging
Correct answer: An open flame candle
Unattended candles are a leading cause of home fires because their open flame can ignite nearby curtains, papers, or other combustibles.
Question 2: What condition makes a building's exit corridors a fire hazard?
- Having multiple exit signs
- Storing boxes and equipment in the hallway (Correct answer)
- Painting corridor walls a light color
- Installing self-closing doors
Correct answer: Storing boxes and equipment in the hallway
Cluttered exit corridors restrict egress width, add fuel load, and may block evacuation routes — all serious fire code violations.
Question 3: What is 'spontaneous combustion' and which material commonly causes it?
- Ignition from sparks; caused by metals
- Self-ignition without an external flame; caused by oily rags or linseed oil-soaked materials (Correct answer)
- Combustion triggered by static electricity; caused by plastic
- Rapid burning caused by oxygen-rich environments; caused by wood
Correct answer: Self-ignition without an external flame; caused by oily rags or linseed oil-soaked materials
Spontaneous combustion occurs when oily rags or linseed oil oxidize and generate enough heat to self-ignite without an external ignition source.
Question 4: Why is it dangerous to store flammable liquids in a non-approved container?
- Non-approved containers may not be labeled correctly
- They may not withstand vapor pressure and can leak or rupture (Correct answer)
- They are not the correct color for identification
- They hold less liquid than approved containers
Correct answer: They may not withstand vapor pressure and can leak or rupture
Approved flammable liquid containers (like FM or UL-listed safety cans) are designed to withstand pressure buildup and prevent accidental ignition.
Question 5: What is the purpose of a fire hazard assessment in a workplace?
- To calculate insurance premiums for the building
- To identify ignition sources, fuel loads, and deficiencies in fire protection (Correct answer)
- To determine the cost of fire suppression systems
- To schedule employee fire safety training dates
Correct answer: To identify ignition sources, fuel loads, and deficiencies in fire protection
A fire hazard assessment systematically identifies risks including ignition sources, combustible materials, and gaps in suppression or detection systems.
Question 6: Which of the following is a leading cause of fires in commercial kitchens?
- Faulty refrigeration units
- Grease buildup in exhaust hoods and ducts (Correct answer)
- Using natural gas burners
- Storing food near heat sources
Correct answer: Grease buildup in exhaust hoods and ducts
Accumulated grease in exhaust hoods and ductwork is highly combustible and is a primary cause of commercial kitchen fires.
