Tork prints a system code on every dispenser and every refill case: match the letters and compatibility is solved — the cleanest scheme in commercial paper. The codes you'll actually meet:

The liner industry sizes to receptacle families, not exact volumes — here's the chart connecting the cans facilities actually own to the cases that fit them:

Trash bag packaging speaks two incompatible thickness languages — mils on low-density bags, microns on high-density liners — and the number on the case means nothing until you know which film you're reading. This guide decodes both, maps the standard commercial sizes, and gives you the…

European gloves wear an EN 388 shield with digits and letters; US gloves wear ANSI/ISEA 105 cut levels A1-A9. Both now use the same TDM cut test, which makes honest conversion possible: EN letter grades in newtons map onto ANSI gram levels. Here is the conversion table, a worked 4X42C decode, and the impact-rating caveat.

N95 is a NIOSH (US) filtering facepiece rating; FFP2 and FFP3 come from Europe's EN 149. The filtration numbers look close — 95%, 94%, 99% — but the test methods, leakage requirements, and legal acceptance differ. Here is the honest conversion logic, the markings that prove authenticity, and what each jurisdiction accepts.

Canada's CSA Z94.1 and the US ANSI/ISEA Z89.1 hard hat standards use the same Type and Class language but differ in testing and certification. Here is how the two systems map, what the shell sticker must say in each jurisdiction, and why dual-certified hats solve the cross-border problem for contractors.

Hard hat suspension types — ratchet vs pinlock and 4-point vs 6-point — decide how a hard hat fits, holds the air gap, and absorbs impact under ANSI/ISEA Z89.1-2014. The suspension, not the shell alone, keeps a falling object off your skull. This guide covers mechanisms, suspension points, hat types, replacement, and a worked example.

Anti-vibration gloves are certified under ISO 10819, which sets transmissibility limits proving a glove passes less vibration to the hand than bare skin. But they mainly damp high-frequency vibration and do little for the low frequencies that dominate breakers. This guide decodes the metrics, the HAVS risk, and a worked crew example.

Heat-resistant gloves must match the heat path — contact, convective, radiant, or molten-metal splash — and a glove strong against one can fail against another. This guide decodes ANSI/ISEA 105 contact-heat levels and the six EN 407 scores, maps materials to each path, and walks a worked example for foundry, welding, and kitchen tasks.

Voluntary respirator use is when employees wear a respirator below OSHA exposure limits even though no rule requires one, yet 29 CFR 1910.134(c)(2) still attaches employer duties. This guide explains Appendix D, the medical-evaluation split between N95 and elastomeric respirators, and a worked example of a compliant program.

Assigned protection factors (APF) are the protection levels OSHA assigns to each respirator class in 29 CFR 1910.134 Table 1. This guide decodes the APF table from quarter mask to pressure-demand SCBA, shows how APF and the exposure limit set the maximum use concentration, and works an example of picking a respirator from a measured exposure.

Fall protection anchor points must either hold 5,000 lb per worker or be engineered by a qualified person to twice the maximum arresting force, under OSHA 1926.502(d)(15). Confusing arrest anchors with positioning or restraint anchors is how anchorages get under-rated. This guide covers every anchor strength and a worked roof example.
