FLSD FLSD Fire Prevention and Inspection 4 — Questions and Answers
Question 1: During a fire inspection, you discover a sprinkler head has been painted over. What is the correct action?
- Document and require replacement of the painted sprinkler head (Correct answer)
- Remove the paint with solvent immediately
- Tag the head as out-of-service and continue operation
- Install a heat shield over the painted head
Correct answer: Document and require replacement of the painted sprinkler head
Painted sprinkler heads must be replaced, not cleaned, because paint alters the thermal response rating and the head cannot be reliably restored.
Question 2: A tenant installs a partition wall that reduces the distance between a sprinkler head and a storage rack to 12 inches. Why is this a fire code violation?
- Sprinklers require a minimum 18-inch clearance below the deflector (Correct answer)
- Sprinklers must be at least 36 inches from any wall or partition
- Storage racks must be metal when within 24 inches of a sprinkler
- Partition walls must be fire-rated if within 2 feet of a sprinkler
Correct answer: Sprinklers require a minimum 18-inch clearance below the deflector
NFPA 13 requires a minimum 18-inch clearance between the sprinkler deflector and the top of storage to ensure proper water distribution.
Question 3: Which type of extinguisher is PROHIBITED from use on a Class K cooking fire involving burning grease?
- Water-mist extinguisher
- Wet chemical extinguisher
- Class ABC dry chemical extinguisher (Correct answer)
- Carbon dioxide extinguisher
Correct answer: Class ABC dry chemical extinguisher
Class ABC dry chemical extinguishers are prohibited on Class K fires because they can cause violent splatter of burning grease and do not effectively cool the fuel.
Question 4: An inspection reveals that exit signs in a high-rise office building are illuminated only by a connection to the building's normal electrical circuit. What deficiency does this represent?
- Exit signs must have a secondary power source such as battery backup or emergency generator (Correct answer)
- Exit signs are only required in stairwells, not office floors
- Exit signs must be internally illuminated with LED only
- Exit signs must be photoluminescent in high-rise buildings
Correct answer: Exit signs must have a secondary power source such as battery backup or emergency generator
Building codes and NFPA 101 require exit signs to be connected to a reliable emergency power source to ensure visibility during a power failure.
Question 5: During a fire drill, it is observed that a stairwell door on the 15th floor is propped open with a wedge. As FLSD, what is the primary concern?
- Propping stairwell doors open compromises the smoke-protected egress path (Correct answer)
- Open stairwell doors reduce exit travel distances
- Propped doors allow firefighters faster access to floors
- Open stairwell doors improve ventilation during a fire
Correct answer: Propping stairwell doors open compromises the smoke-protected egress path
Stairwells are designed as smoke-protected egress paths; propping doors open allows smoke to infiltrate the stairwell, endangering evacuating occupants.
Question 6: A restaurant installs a new deep fryer but does not extend the kitchen hood exhaust duct to cover it. Which hazard does this create?
- Grease-laden vapors from the fryer will not be captured, increasing fire risk in the cooking area (Correct answer)
- The fryer will overheat because airflow is reduced
- The existing hood will lose its UL listing due to added equipment
- Employees will be exposed to excess noise without proper ventilation
Correct answer: Grease-laden vapors from the fryer will not be captured, increasing fire risk in the cooking area
Kitchen exhaust hoods must cover all cooking equipment to capture grease-laden vapors; uncovered equipment allows grease to accumulate on surfaces and increases fire risk.
Question 7: What is the purpose of a Knox Box installed at a building's entrance?
- To provide the fire department with secured key access for emergency entry without forcing doors (Correct answer)
- To store fire extinguishers near the building entrance
- To house the building's fire alarm control panel key card
- To secure the standpipe hose cabinet on the exterior wall
Correct answer: To provide the fire department with secured key access for emergency entry without forcing doors
A Knox Box contains building keys or access cards so responding firefighters can enter locked buildings rapidly without causing property damage.
