FST Fire Prevention & Hazardous Materials Management 5 — Questions and Answers
Question 1: During a fire prevention inspection of a spray painting booth, which hazard should the inspector prioritize?
- Excessive lighting inside the booth
- Accumulation of paint residue and inadequate ventilation creating a flammable atmosphere (Correct answer)
- The type of paint colors being applied
- Lack of a fire extinguisher color label inside the booth
Correct answer: Accumulation of paint residue and inadequate ventilation creating a flammable atmosphere
Flammable paint vapors combined with residue buildup in a poorly ventilated spray booth create explosive concentrations and represent the top fire hazard.
Question 2: According to NFPA 1, what is the minimum fire flow requirement used during fire prevention inspections to assess adequacy of water supply?
- It is a fixed 500 gpm for all occupancies
- It varies based on the occupancy type, construction, and area of the building (Correct answer)
- It is determined solely by the local utility company
- It only applies to high-rise buildings
Correct answer: It varies based on the occupancy type, construction, and area of the building
Minimum fire flow requirements vary with building size, occupancy classification, and construction type, as specified in NFPA 1 and supporting annexes.
Question 3: When radioactive materials are involved in a hazmat incident, what is the correct initial action for fire personnel without specialized radiological training?
- Approach to within 10 feet to read placards
- Establish a safe perimeter, evacuate the area, and request specialized radiological assistance (Correct answer)
- Apply water fog immediately to suppress contamination spread
- Don standard SCBA and proceed with fire attack
Correct answer: Establish a safe perimeter, evacuate the area, and request specialized radiological assistance
Unprotected personnel should not approach radiological incidents; establishing a perimeter and summoning specialists protects responders from radiation exposure.
Question 4: A facility stores compressed chlorine gas cylinders. Under NFPA 1, in what occupancy hazard classification would this storage most likely fall?
- Low hazard
- Ordinary hazard Group 1
- High hazard (Correct answer)
- Ordinary hazard Group 2
Correct answer: High hazard
Chlorine gas is a toxic and reactive compressed gas; storage of such materials places the occupancy in the high-hazard category under NFPA 1.
Question 5: What is the role of Local Emergency Planning Committees (LEPCs) under SARA Title III?
- To enforce OSHA workplace safety citations
- To develop emergency response plans and coordinate community preparedness for hazardous chemical incidents (Correct answer)
- To issue fines for Tier II reporting violations
- To approve building permits for chemical facilities
Correct answer: To develop emergency response plans and coordinate community preparedness for hazardous chemical incidents
LEPCs are required by EPCRA (SARA Title III) to develop local emergency response plans addressing hazardous chemical hazards within their planning district.
Question 6: Which document describes the specific fire and life safety requirements for a building based on its use and occupancy classification under the International Fire Code (IFC)?
- Certificate of Occupancy
- Fire Safety Inspection Report
- Occupancy Classification Schedule
- Operational Permit (Correct answer)
Correct answer: Operational Permit
Under the IFC, an operational permit specifies the conditions and requirements under which a specific high-hazard operation or occupancy may be conducted.
Question 7: A cryogenic liquid oxygen storage tank is installed at a medical facility. What is the primary fire hazard associated with liquid oxygen?
- It is highly flammable and will ignite spontaneously
- It greatly accelerates the burning of ordinary combustibles that come into contact with it (Correct answer)
- It produces toxic fumes when released
- It reacts explosively with water
Correct answer: It greatly accelerates the burning of ordinary combustibles that come into contact with it
Liquid oxygen is a strong oxidizer that dramatically increases the burn rate of ordinary combustibles, making even materials that normally do not burn intensely flammable.
