OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at https://www.osha.gov.

Dear Schreiber:

This is in response to your letter of March 7 regarding the size of fire extinguisher for construction equipment.

Per our conversation of May 23, the Occupational Safety and Health Administration‹s (OSHA) fire protection and prevention standard (29 CFR 1926.150 – Subpart F) does not state any specific weight or size requirements for fire extinguishers on construction equipment. As part of a fire prevention plan, a hazard assessment should be performed in order to determine potential hazards that exist and the types of fire fighting equipment that would be necessary.

We appreciate your interest in employee safety and health. If you require further assistance, please contact the [Office of General Industry Enforcement at (202)693-1850].
