“(c) Portable firefighting equipment—(1) Fire extinguishers and small hose lines. (i) 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. Travel distance from any point of the protected area to the nearest fire extinguisher shall not exceed 100 feet.”
“(v) Extinguishers and water drums, subject to freezing, shall be protected from freezing.”
“(vi) A fire extinguisher, rated not less than 10B, shall be provided within 50 feet of wherever more than 5 gallons of flammable or combustible liquids or 5 pounds of flammable gas are being used on the jobsite. This requirement does not apply to the integral fuel tanks of motor vehicles.”
“(iii) During demolition involving combustible materials, charged hose lines, supplied by hydrants, water tank trucks with pumps, or equivalent, shall be made available.”
“(ii) During demolition or alterations, existing automatic sprinkler installations shall be retained in service as long as reasonable. The operation of sprinkler control valves shall be permitted only by properly authorized persons.

Free practice questions on 29 CFR 1926.150
Question 1
A contractor is renovating a building and keeps a charged fire hose line on site for fire protection. The hose couplings have a different thread than the local fire department's equipment. The safety professional is asked what the contractor must do about this mismatch. Which action does the rule require?
Show answer and source
Answer: A. Provide adapters, or equivalent, so the hose connections work with the local fire department's equipment
OSHA's construction fire protection rule puts the duty on the contractor to supply adapters, or an equivalent, when hose connections do not match local firefighting equipment. Making the fire department change its couplings shifts the duty to the wrong party. Ignoring the mismatch or removing the hose does not meet the requirement.
Answer A rests on
29 CFR 1926.150(c)(2)(ii)(opens ecfr.gov in a new tab)“If fire hose connections are not compatible with local firefighting equipment, the contractor shall provide adapters, or equivalent, to permit connections.”
Question 2
A general contractor has set up a siren and a site telephone system so that employees and the local fire department can be alerted to an emergency. During an audit, the safety professional finds the alarm code and reporting instructions posted only on the wall of the site office. Which change is needed to comply?
Show answer and source
Answer: C. Post the alarm code and reporting instructions conspicuously at phones and at employee entrances
OSHA's construction fire protection rule requires the alarm code and reporting instructions to be conspicuously posted at phones and at employee entrances. A posting in one office does not cover those places. Telling only the fire department or using a handout leaves employees without the visible instructions the rule requires.
On the job
On a warehouse construction job, a site superintendent walks the perimeter and sees the alarm code and reporting instructions taped inside the trailer door only. Because the instructions must be conspicuously posted at phones and at employee entrances, he has laminated copies mounted at each phone station and beside the gate where workers enter the site.

Answer C rests on
29 CFR 1926.150(e)(2)(opens ecfr.gov in a new tab)“The alarm code and reporting instructions shall be conspicuously posted at phones and at employee entrances.”
