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.

Fire extinguisher placement requirements set how far a worker may travel to reach a unit and how high it may be mounted, and getting either wrong is a common OSHA citation. This guide breaks down the NFPA 10 travel-distance limits by class, the mounting-height and clearance rules, OSHA 1910.157 accessibility, and a worked facility example.

Fire extinguisher types describe the agent inside — dry chemical, CO2, water, wet chemical, clean agent, or dry powder — a separate decision from the A-B-C-D-K fire class on the label. This guide explains each agent, the classes it is rated for, and its residue under NFPA 10, plus a worked facility example.

Fire extinguisher classes (A, B, C, D, and K) tell you which fires a unit can safely fight, and using the wrong class can spread a fire instead of stopping it. This guide decodes every class under NFPA 10, explains the numerical A and B ratings on the label, covers the PASS discharge method, and walks a worked example of equipping a workshop.

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.

The mil number on a box of nitrile gloves quietly decides how long they last, how much chemical they hold off, and how much you can feel through them. This guide explains nitrile glove thickness, what a mil measures, how 2-mil exam gloves differ from 8-mil industrial gloves, and which thickness to choose by task.

A PAPR uses a blower to push filtered air into a hood or mask, giving higher protection and far more comfort than a tight-fitting respirator, often without a fit test. This guide explains how a powered air-purifying respirator works, its assigned protection factor, how it compares to half- and full-face respirators, and who actually needs one.

Fluorescent yellow-green and orange-red are both ANSI-compliant hi-vis colors, but they are conspicuous against different backgrounds, which makes the color a real safety choice. This guide explains hi-vis color meaning, how the background colors and retroreflective tape work together, and which color to choose by environment.

A disposable coverall that stops dust will not stop a chemical spray, and the fabric name on the box tells you which is which. This guide explains disposable coverall types, the Type 3 to Type 6 protection system, and how Tyvek, Tychem, ProShield, and KleenGuard map to particulate, light-spray, and liquid-chemical hazards.

A fall protection harness must be inspected before every use, because a cut web or a deployed impact indicator can mean the difference between a stopped fall and a fatal one. This checklist walks through webbing, stitching, D-rings, buckles, and impact indicators, explains inspection frequency, and gives the rules for when to retire a harness.

A shock-absorbing lanyard and a self-retracting lifeline both connect your harness to an anchor, but they behave differently in a fall, and choosing wrong can mean too little clearance to stop. This guide compares the two on free-fall distance, clearance, arrest force, and cost, and shows which connector fits each tie-off.

A personal fall arrest system is only as strong as its weakest link, and the ABCDs framework is how to make sure no link is missing. This guide explains the ABCDs of fall protection, Anchorage, Body wear, Connectors, and Descent or rescue, covers the OSHA trigger heights, and shows how to calculate the fall clearance you actually need.
