A fire blanket cannot satisfy an OSHA extinguisher requirement - 29 CFR 1910.157 governs portable fire extinguishers and does not mention blankets at all, and a blanket carries no class or capacity rating. This guide covers the rating gap, the two jobs a blanket genuinely does better, and where it is the wrong tool entirely.

A charged fire extinguisher is a pressure vessel and does not belong in a bin. There is no single federal disposal rule - household waste is excluded from RCRA Subtitle C and handed to state and local authorities instead. This guide covers rechargeable vs disposable, safe depressurising, and the extra duty a workplace owes.

There is no federal chemical-segregation matrix, which is why so much guidance on this topic is subtly wrong. This guide covers the one explicit rule in 1910.106(d)(7)(iv), the cabinet quantities at (d)(3)(i), the pairs that cause most facility incidents, and an eight-step segregation walk that produces findings rather than reassurance.

OSHA 1910.1200(e) requires a written hazard communication program at each workplace - not just a binder of safety data sheets. This guide covers the three mandatory contents, the chemical list rule that trips most programs, and the training obligation in paragraph (h). Includes a seven-step method for building the chemical list.

Every safety data sheet in the US carries the same 16 sections in the same order under OSHA 29 CFR 1910.1200 - so an SDS is a map, not a document you read front to back. This guide shows which sections carry regulatory weight and which four OSHA does not enforce. Covers Section 2 hazards, Section 8 PPE, first aid and a worked example.

HazCom and HAZWOPER are separate standards with separate triggers, and conflating them is expensive in both directions. This guide sets out the five operations covered by 1910.120(a)(1), how paragraph (a)(2) limits which parts apply, and where the incidental-release line falls for an ordinary facility responding to a spill.

A poisoned catalytic bead sensor does not fault, blank or warn you. It reads low, silently, in a flammable atmosphere. This guide covers the compound classes that cause it, the difference between poisoning and inhibition, why calibration cannot fix it, and the daily function check that turns a silent failure into a visible one.

OSHA never writes 'yellow A-frame' into a standard. What 29 CFR 1910.22 requires is that walking-working surfaces be kept clean, orderly, and — where possible — dry, and that hazardous conditions be corrected or guarded. Posted warnings during mopping and spills are the universally recognized way…

OSHA's sanitation standard (29 CFR 1910.141) sets the floor for general industry: toilet facilities provided by workforce size, kept sanitary, with hand-washing provision — and employees must have availability, meaning prompt access without unreasonable restriction (a point OSHA has reinforced in…

What Happens If a Respirator Doesn't Fit: A respirator that does not seal properly against the face stops working as rated. Fit failure collapses the assigned protection factor (APF) - a half-face respirator with an APF of 10 can deliver as little as 2× protection if the face seal leaks.

Can You Reuse an N95: N95 filtering facepiece respirators (FFRs) are designated as single-use devices under NIOSH's 42 CFR Part 84 approval system. NIOSH does not approve any N95 for routine reuse.

NIOSH vs. OSHA Explained (2026 Guide): NIOSH (National Institute for Occupational Safety and Health) is a research and certification agency within the CDC that approves PPE and sets recommended exposure limits.
