CFI Hazardous Materials Storage 3 — Questions and Answers
Question 1: Under IFC Section 5003, what is a 'control area' in the context of hazardous materials storage?
- An area where hazmat spills are contained by berms
- A space within a building where hazardous materials quantities are limited by code (Correct answer)
- The loading dock designated for hazmat deliveries
- A fire department command zone established during an incident
Correct answer: A space within a building where hazardous materials quantities are limited by code
A control area is a building space where MAQs of hazardous materials are permitted, bounded by fire-resistance-rated construction.
Question 2: How many control areas are permitted per floor in a sprinklered building under the IFC?
- One per floor regardless of sprinklers
- Two per floor
- Four per floor (Correct answer)
- Unlimited with proper separation
Correct answer: Four per floor
The IFC generally permits up to four control areas per floor in sprinklered buildings, with MAQ multipliers applied.
Question 3: What secondary containment capacity is typically required for flammable liquid storage inside a building per NFPA 30?
- 10% of the largest container volume
- The volume of the largest single container
- 110% of the largest single container volume (Correct answer)
- The total volume of all containers combined
Correct answer: 110% of the largest single container volume
NFPA 30 requires secondary containment capable of holding at least 110% of the volume of the largest container to account for the container plus a safety margin.
Question 4: Which storage arrangement is required for incompatible hazardous materials such as acids and bases?
- Store in the same room but on opposite shelves
- Segregate by at least one hour fire-resistance-rated construction or physical separation (Correct answer)
- Use the same secondary containment system to simplify cleanup
- Label containers clearly and store within 3 feet of each other
Correct answer: Segregate by at least one hour fire-resistance-rated construction or physical separation
Incompatible materials must be physically segregated by rated construction or sufficient distance to prevent contact during a spill or fire.
Question 5: What is the minimum aisle width required in a hazardous materials storage room to allow emergency egress per IFC?
- 18 inches
- 24 inches
- 36 inches (Correct answer)
- 44 inches
Correct answer: 36 inches
The IFC requires a minimum 36-inch aisle width in hazardous materials storage areas to permit emergency egress and emergency responder access.
Question 6: At what temperature must flammable liquids storage rooms be maintained to stay below the flash point of Class IA liquids?
- Below 32°F
- Below 73°F
- Below 100°F
- Temperature control is not required by code (Correct answer)
Correct answer: Temperature control is not required by code
NFPA 30 does not require specific temperature control for storage rooms but does require ventilation and elimination of ignition sources to manage vapor accumulation.
Question 7: A fire inspector finds drums of flammable liquid stored directly on the floor without pallets in a storage room. What is the primary concern?
- Drums may corrode faster at floor level
- Floor drains could be blocked preventing spill containment drainage (Correct answer)
- Forklifts cannot access drums stored at floor level
- This storage method is fully compliant with NFPA 30
Correct answer: Floor drains could be blocked preventing spill containment drainage
Drums stored directly on the floor without proper containment pallets can block floor drains and prevent proper spill control drainage.
