Fire extinguisher inspection runs on a fixed cadence: a monthly visual check, an annual maintenance by a qualified servicer, and hydrostatic testing every 5 or 12 years by extinguisher type, under OSHA 1910.157 and NFPA 10. This guide explains each interval, who performs it, how to document the tag, and walks a worked example for a facility.

Most workplace fires start small enough to stop with a portable extinguisher, but only when you pick the right class and use it correctly. This guide explains the PASS method step by step, decodes fire classes A through K, walks through a real ABC unit, and covers the OSHA training rule and when to evacuate.
