Every 29 CFR 1910 and 1926 section carrying a practical safety duty, indexed with its official CFR title and a plain-English summary written from the regulation itself. Includes the general industry versus construction crosswalk and the incorporation-by-reference table showing which ANSI and ASTM editions OSHA actually enforces.

Three systems certify work boots in North America and Europe and they do not share notation: ASTM F2413 in the United States, CSA Z195 in Canada, and EN ISO 20345 in Europe. This guide decodes all three, compares the toe impact values honestly, and answers whether an imported S3 or CSA boot satisfies OSHA 29 CFR 1910.136.

Neither of the two OSHA standards governing compressed gas cylinder storage contains a requirement to post a sign at the storage area. This guide gives what they do require, names the four separate sources that compel the signage facilities actually need, and maps signs to hazard class with the NFPA 704 diamond decoded.

The label on a machine and the sign on the wall share signal words and colours but belong to different standards, with different owners and different replacement duties. This guide contrasts ANSI Z535.4 and Z535.2 point by point, then walks the relabelling of a rebuilt machine whose original label set was lost to paint.

Inspection tagging has drifted into folk practice, and most of the tags on a typical rack satisfy no federal requirement at all. This guide sorts them equipment by equipment into required, evidence of a required inspection, and pure convention, then gives the hard specification that the tags OSHA does compel by name have to meet.

Wheel chocks are required by OSHA in three specific situations, none of them in the DOT vehicle equipment rules. This guide gives the exact citations, the quarter-diameter sizing convention and what overrides it, the difference between a vehicle chock and a pallet-jack chock, and how to place a chock so it actually holds.

FMCSA amended 393.95 twice in 2026, both times by deletion: liquid-burning flares ceased to be an accepted warning device in March, and the spare-fuse requirement was removed in April. This guide gives what the section still requires, the extinguisher ratings and condition rules, and the 392.22 placement patterns for every road type.

Exit signage is one of the few places where general industry and construction genuinely diverge on the specification of the same object, and the divergence runs the opposite way to what most people expect. This guide sets 1910.37(b) and 1926.200(d) side by side, adds the NFPA 101 compliance route, and walks a mixed-site audit.

Almost every floor marking colour chart in circulation cites an OSHA standard that does not contain what is attributed to it. This guide labels each claim myth or fact with the actual citation attached, shows which floor markings genuinely are mandatory and why, and presents the colour convention clearly as convention rather than as law.

Federal OSHA has no general-industry pipe-marking standard, and the 1956 edition it does incorporate is 67 years behind the one vendors sell today. This guide locates the duty section by section, then gives the two tables a specifier actually needs: the full ASME A13.1-2023 colour scheme and the marker size schedule by pipe diameter.

Fiberglass or aluminum comes down to one rule: OSHA requires non-conductive siderails wherever the worker or the ladder could contact exposed energized equipment. This guide explains what that trigger covers, why a fiberglass ladder is not an insulator, and how the two materials compare on weight, UV service life, corrosion and cost.

OSHA-format and ANSI Z535 signs are both legally acceptable, for entirely different reasons. This guide compares the two sign faces element by element, explains what an ANSI compliant vendor badge does not tell a buyer, and gives five questions for choosing a system, with migration staging and purchase specification language.
