Switching equipment off proves nothing - an electrically safe work condition exists only after conductors are disconnected, locked and tagged, and tested dead by a qualified person. This guide decodes OSHA 1910.333’s deenergize-default rule, the verification sequence, grounding, and when energized work can be justified.

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.
