Member, United States House of Representatives

Dear Congresswoman Slaughter:

Thank you for your inquiry of March 21, addressed to Ms. Ruth Knight, Director of the Office of Intra-Government Affairs, on behalf of your constituent, Mr. Sam Cuckovich.

The concerns expressed by Mr. Cuckovich are addressed and highlighted in the enclosed Occupational Safety and Health Administration (OSHA) Fire Protection Standards at 29 CFR 1910.157(e)(1) and 1910.157(e)(3). These standards specify that employers are responsible for inspecting and maintaining their fire extinguishers in use and for keeping, retaining, and making related records available to the Assistant Secretary upon request. The standards do not require servicing vendors to certify to the owner that servicing has been done in accordance with OSHA of National Fire Protection Association standards. Such a requirement is at the discretion of the contracting employer.
