CHST - Construction Health and Safety Technician Emergency and Fire Preparedness Questions and Answers

Question 1

According to OSHA standard 29 CFR 1926.150(c)(1)(i), what is the minimum fire extinguisher rating that must be provided for each 3,000 square feet of a protected building area on a construction site?

Accepted Answer

A 2A rated extinguisher

Answer

OSHA 29 CFR 1926.150(c)(1)(i) explicitly states, 'A fire extinguisher, rated not less than 2A, shall be provided for each 3,000 square feet of the protected building area, or major fraction thereof.' While other types of extinguishers are required for specific hazards (like flammable liquids), the 2A rating is the minimum general requirement for building areas.

Question 2

A construction site has 15 employees. An Emergency Action Plan (EAP) is required. Which of the following elements is a mandatory component of this plan according to 29 CFR 1926.35?

Accepted Answer

Procedures for employees who remain to operate critical equipment before they evacuate.

Answer

According to 29 CFR 1926.35(b), an EAP must include several elements, one of which is 'Procedures to be followed by employees who remain to operate critical plant operations before they evacuate.' Because the site has more than 10 employees, the plan must be in writing and kept at the workplace.

Question 3

During a site walkthrough, a safety technician observes a pallet of materials partially blocking a designated emergency exit route from a building. This condition is a violation primarily because it:

Accepted Answer

impedes free and unobstructed egress during an emergency.

Answer

OSHA 29 CFR 1926.34(a) requires that exits be arranged and maintained to provide 'free and unobstructed egress from all parts of the building or structure at all times when it is occupied.' While it is also a housekeeping issue and a trip hazard, the most critical violation is the obstruction of a required means of egress for an emergency.

Question 4

In the absence of an infirmary, clinic, or hospital in near proximity to the workplace, what does OSHA 29 CFR 1926.50 require for a construction site?

Accepted Answer

A person with a valid certificate in first-aid training must be available at the worksite.

Answer

OSHA 29 CFR 1926.50(c) states that when a medical facility is not reasonably accessible, 'a person who has a valid certificate in first-aid training...shall be available at the worksite to render first aid.'

Question 5

Which of the following is a key element that MUST be included in a company's written Fire Prevention Plan (FPP) according to the standard referenced by OSHA for construction (29 CFR 1910.39)?

Accepted Answer

A list of major fire hazards and procedures for their control.

Answer

A Fire Prevention Plan's purpose is to prevent fires from starting. According to 29 CFR 1910.39(c), the plan must include 'A list of all major fire hazards, proper handling and storage procedures for hazardous materials, [and] potential ignition sources and their control'. The other options are required elements of an Emergency Action Plan (EAP), not a Fire Prevention Plan.
