Who is responsible
Under OSHA 29 CFR 1910.157, the employer carries the duty for portable fire extinguisher inspection, maintenance, and testing. OSHA also says workplace extinguishers are kept fully charged and operable, and in their designated places, except while they are in use. If you are building a simple tracking process, start with the basics on Fire Inspection Log features and then compare your routine with the regulation at OSHA 1910.157.
Monthly, annual, 6 year, hydrostatic
OSHA calls for a monthly visual inspection where the standard applies. It also calls for an annual maintenance check, and the annual maintenance date is recorded. For stored pressure dry chemical extinguishers that require a 12 year hydrostatic test, OSHA says they are emptied and maintained every 6 years, and the 6 year count starts again when the unit is recharged or hydrostatically tested. OSHA Table L-1 sets hydrostatic test intervals by extinguisher type, and testing is done by trained people with suitable equipment. If you want a short reference while you work, see how often to inspect and the inspection checklist.
Travel distance and training
When extinguishers are provided for employee use, OSHA ties placement to travel distance. The rule says 75 feet or less for Class A, 50 feet or less for Class B, and 75 feet or less for Class D from the combustible metal work area. Class C follows the Class A or Class B pattern. OSHA also calls for education on general use and on the hazards of incipient stage firefighting at hire and at least once a year, and people designated to use the equipment get training at assignment and at least once a year. For definitions and plain-language terms, the glossary can help.
How a log helps, and where it stops
A reminder log helps you capture the monthly visual check, the annual maintenance date, and note fields for service history. It can also help you track the last annual maintenance date and keep an eye on whether a unit needs attention or alternate equivalent protection while it is removed for maintenance or recharging. A log does not replace the regulation, and it does not guarantee any inspection outcome. If you want the source context behind the standard family, NFPA lists NFPA 10 as the Standard for Portable Fire Extinguishers, and Fire Inspection Log is not part of NFPA.
This is a reminder log, not an inspection and not code compliance. Not a substitute for a licensed fire protection inspection. Rules differ by workplace and by the fire code your local authority uses. Fire Inspection Log is not part of OSHA, NFPA, or any fire marshal office.
