Custom wording does not create a custom exemption: a sign you wrote owes exactly the same class, colour, construction and wording duties as one you bought. This ten-step design checklist works through them in order, and names the defect that damages a sign set most, which is DANGER placed on a hazard that is merely potential.

No OSHA standard requires a rack load capacity plaque; ANSI MH16.1 does, and it places the duty on the rack owner rather than on the manufacturer or installer. This guide walks a distribution centre zone by zone, from the dock through to the electrical panels, stating for each what is required, by whom, and what the recurring defect is.

No OSHA standard requires a second language on a safety sign, and OSHA has confirmed it requires no English either. What it requires is comprehension. This decision guide walks the branch points in order, from surveying who is actually exposed to choosing symbols over translation, and records why each choice is defensible.

Foot pain advice is written for trainers, not for boots with a certified toe cap. This guide maps plantar fasciitis, flat feet, wide feet and diabetic neuropathy onto the work-boot features that address them, using AAOS and NIDDK guidance, plus the two conflicts unique to safety footwear: the toe cap cannot be stretched.

LED flare kits are widely sold as DOT approved, and they are not. This guide gives the FMVSS No. 125 construction specification a triangle must actually meet, the 49 CFR 392.22 placement geometry for two-lane and divided highways, and the FMCSA exemption record that explains where the claim comes from and why it does not generalise.

Cargo securement is two independent tests and you must pass both: a minimum tiedown count under 49 CFR 393.110, and an aggregate working load limit of at least half the cargo weight under 393.106(d). This guide walks both with real numbers, and explains why the break-strength figure on the packaging must never enter the calculation.

OSHA 29 CFR 1910.252 governs every welding, cutting and brazing job in general industry, and it turns on numbers most welders have never been shown: a 35-foot combustible radius, a half-hour fire watch after the arc stops, and three separate conditions that force mechanical ventilation. This guide walks the job in order.

The general industry silica standard has the same exposure limit as the construction rule and none of its shortcuts. There is no Table 1 to follow, so exposure assessment is not optional. This guide covers which rule governs your work, the two limits, the written exposure control plan and the medical surveillance clock.

OSHA permissible exposure limits live in three separate tables that work three different ways, and 29 CFR 1910.1000(d) supplies the arithmetic for deciding whether a measured exposure is over the limit. This guide works both formulae with real numbers, decodes the ceiling and peak columns, and explains why most PELs date from 1971.

OSHA runs two lead standards with the same exposure limit and very different machinery. Construction presumes exposure from the task itself before anyone samples the air; general industry does not. And the blood-lead level that forces a worker off the job differs between them. This guide sets both ladders out side by side.

OSHA 29 CFR 1910.1030 covers every employee with reasonably anticipated contact with blood or other infectious materials, and it reaches well beyond healthcare. This guide sets out the eight duties the standard creates, who actually counts as exposed, the hepatitis B vaccine clock, and the two very different record retention periods.

Every control in the OSHA construction asbestos standard scales off which of four work classes the job falls into, and misclassifying it is the most expensive mistake available. This guide sets out what separates Class I from Class II, III and IV, what each class triggers, and the two exposure limits that apply throughout.
