Emergency and Fire Preparedness Flashcards

Under OSHA 1926.35, what must be included in an Emergency Action Plan (EAP) for construction sites?

Answer: Evacuation procedures and routes, procedures for employees who remain to operate critical operations, procedures to account for all employees after evacuation, rescue and medical duties, means of reporting emergencies, and names of contacts for more information

OSHA 1926.35 requires an EAP to include evacuation procedures and routes, procedures for remaining employees, accountability procedures, rescue and medical duties, emergency reporting procedures, and a contact person for more information.

Which class of fire involves energized electrical equipment, and why must water never be used to extinguish it?

Answer: Class C — energized electrical equipment; water is conductive and creates an electrocution path from the energized equipment to the person using the extinguisher

Class C fires involve energized electrical equipment. Water is an electrical conductor, so spraying water on energized electrical fires creates an electrocution path from the energized equipment through the water stream to the operator.

Under OSHA 1910.38, when must workers be trained on the Emergency Action Plan?

Answer: At hire, whenever workers' responsibilities change, whenever the EAP is revised, and whenever the employer believes workers have not retained sufficient knowledge

OSHA requires EAP training at initial hire, upon change of responsibilities, when the EAP is updated, and whenever the employer believes workers have not retained sufficient knowledge.

Under OSHA 1926.150(c), what minimum extinguisher rating is required for Class A (ordinary combustible) fire hazards on construction sites?

Answer: 2-A

OSHA 1926.150(c)(1)(ii) requires a minimum 2-A rated extinguisher for ordinary combustible (Class A) fire hazards on construction sites — the '2-A' rating represents an extinguishing capacity equivalent to 2.5 gallons of water.

What is the purpose of a Hot Work Permit system, and how long must a fire watch remain after hot work is completed?

Answer: A Hot Work Permit authorizes and controls spark-producing work in areas where fire hazards exist; a fire watch must remain for at least 30 minutes after hot work ends

Hot Work Permits control fire risks from spark-producing work (welding, cutting, grinding) by requiring hazard assessment, mitigation, and a fire watch for at least 30 minutes after the work ends — since hot surfaces can smolder and ignite hours later.

Under OSHA 1926.150(b), a construction site firefighting program must include which minimum elements?

Answer: Adequate fire extinguishers, an alarm system to notify all workers, and established procedures for calling the fire department

OSHA 1926.150(b) requires a firefighting program that at minimum includes portable fire extinguishers, a communication system to notify workers, and procedures for contacting the fire department.
