Certified Safety Professional Exam Emergency Response and Fire Protection 2 — Questions and Answers
Question 1: In the context of hazardous materials emergency response, what does BLEVE stand for?
- Boiling Liquid Expanding Vapor Explosion (Correct answer)
- Burst Level Emergency Venting Event
- Burning Liquid Evaporation Venting Explosion
- Basic Liquid Emergency Vapor Evaluation
Correct answer: Boiling Liquid Expanding Vapor Explosion
A BLEVE (Boiling Liquid Expanding Vapor Explosion) occurs when a vessel containing pressurized liquid fails, rapidly releasing and igniting expanding vapor.
Question 2: Under OSHA's HAZWOPER standard (29 CFR 1910.120), how many hours of initial training are required for employees who respond to hazardous substance releases (operations level)?
- 8 hours
- 16 hours
- 24 hours (Correct answer)
- 40 hours
Correct answer: 24 hours
HAZWOPER operations level responders who take defensive action at the perimeter require a minimum of 8 hours, while first responders at the operations level need 8 hours; general site workers need 40 hours.
Question 3: What is the primary function of a fire watch?
- To inspect fire extinguishers monthly
- To monitor for fires during and after hot work operations (Correct answer)
- To conduct quarterly fire drills
- To review fire protection plans
Correct answer: To monitor for fires during and after hot work operations
A fire watch involves a designated person who monitors the hot work area during operations and for at least 30 minutes after completion to detect and extinguish any fires.
Question 4: What is the flash point of a flammable liquid as defined by OSHA?
- The temperature at which it auto-ignites without a spark
- The minimum temperature at which it gives off sufficient vapor to form an ignitable mixture near the surface (Correct answer)
- The boiling point at standard pressure
- The temperature at which the liquid burns continuously
Correct answer: The minimum temperature at which it gives off sufficient vapor to form an ignitable mixture near the surface
Flash point is the minimum temperature at which a liquid produces enough vapor to ignite momentarily when an ignition source is applied near the surface.
Question 5: According to NFPA 72, audible fire alarm notification appliances in occupied spaces must produce a sound level of at least how many dB above ambient noise?
- 5 dB
- 10 dB
- 15 dB (Correct answer)
- 20 dB
Correct answer: 15 dB
NFPA 72 requires audible alarms to produce at least 15 dB above the average ambient sound level, or 5 dB above the maximum sound level, whichever is greater.
Question 6: Which agency administers the Emergency Planning and Community Right-to-Know Act (EPCRA)?
- OSHA
- EPA (Correct answer)
- FEMA
- DOT
Correct answer: EPA
The Environmental Protection Agency (EPA) administers EPCRA (SARA Title III), which requires facilities to report hazardous chemical inventories to local emergency planners.
