What is the lower explosive limit (LEL) in the context of flammable gas/vapor hazards?
Answer: The minimum concentration of gas or vapor in air that will ignite
The LEL is the minimum concentration of a flammable gas or vapor in air below which ignition cannot occur because the mixture is too lean.
During a hazardous materials incident, the 'cold zone' in emergency response terminology refers to which area?
Answer: The area away from contamination where command, medical, and support operations are staged
The cold (support) zone is outside the contamination areas and serves as the staging area for incident command, medical support, and uncontaminated resources.
What type of sprinkler head activates only in the zone where heat is detected, minimizing water damage?
Answer: Wet pipe system sprinkler
In a wet pipe system, each sprinkler head operates independently when its fusible element melts, activating only the heads in the fire zone.
What is the purpose of a Site Emergency Response Plan (SERP) under OSHA HAZWOPER?
Answer: To describe how a facility will respond to uncontrolled hazardous substance releases
A SERP under HAZWOPER describes the organizational structure, procedures, and resources for responding to hazardous substance emergencies at a facility.
Which chemical fire suppression agent is most effective for Class K (kitchen/cooking oil) fires?
Answer: Wet chemical (potassium-based)
Wet chemical agents containing potassium salts saponify cooking oils, creating a foam barrier that suppresses flame and prevents re-ignition in Class K fires.
Under NFPA 101 (Life Safety Code), what is the maximum travel distance to the nearest exit in a typical business occupancy with a sprinkler system?
Answer: 200 feet
NFPA 101 allows a maximum travel distance of 200 feet in a sprinklered business occupancy; unsprinklered business occupancies are limited to 200 feet as well in this occupancy type.
