Every one of these purchases is driven by a rule — an OSHA section, an ANSI class, or a hiring client's checklist. Each guide explains the rule in plain language, decodes the marking system, and lists specific, well-reviewed products that map to it. The guides contain affiliate links and each says so.
OSHA 1926.50 and what ANSI Z308.1 Class A vs Class B actually commits a kit to — and which class a working site needs.
The two numbers in 1926.150 — 2A per 3,000 sq ft within 100 ft, 10B within 50 ft of fuel — and how to read "3-A:40-B:C".
The 6-foot rule, the three parts of a personal fall arrest system, and why the anchor is the part that matters.
Z89.1 decoded: Type I vs II, Class G/E/C, when to replace, and what the letters mean around electrical work.
ANSI/ISEA 107 Class 2 vs Class 3 in plain language, when highway rules require which, and why Class 3 means sleeves.
1926.102, the Z87 vs Z87+ marking, side protection, and the fogging problem that decides whether glasses get worn.
ANSI/ISEA 105 cut levels A1–A9 decoded — which level each trade actually needs, and where coated general-purpose gloves are the right answer.
N95 vs P100, what OSHA's silica standard requires on cutting and grinding tasks, and the program requirements that come with required use.
The 90 dBA rule, what NRR honestly buys you, plugs vs muffs — and the protectors crews actually keep wearing.
Foam plugs win on protection per dollar, muffs win on getting worn — which one fits continuous cutting, intermittent noise, heat and cold.
All of it on one page: the rule, the label to check, and one proven pick per category.
The high-turnover cheap stuff — earplugs, glasses, gloves, headlamps, knee pads — picked by real purchase volume.
