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.

Scaffolds have their own OSHA subpart, their own fall-protection height and their own inspection rule, and the numbers differ from the ones crews recite. This reference explains 29 CFR 1926 Subpart L with paragraph citations: the 4x capacity factor, the 10-foot trigger, the 4:1 tipping ratio, planking gaps and guardrail height.

OSHA assigns every fall protection duty to a named role: the competent person who inspects and corrects, the qualified person who engineers anchors and lifelines, the authorized person who uses the systems. This guide decodes the 1926.32 definitions, maps every Subpart M duty to its role, and staffs a real roofing job.

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.

A fall protection harness must be inspected before every use, because a cut web or a deployed impact indicator can mean the difference between a stopped fall and a fatal one. This checklist walks through webbing, stitching, D-rings, buckles, and impact indicators, explains inspection frequency, and gives the rules for when to retire a harness.

OSHA 29 CFR 1926.1153 is the construction silica standard. It sets a PEL of 50 µg/m³, allows Table 1 engineering controls as a compliance option, and requires written exposure control plans and medical surveillance when applicable. This guide covers each compliance option and respirator selection for concrete grinding and masonry work.
