What 29 CFR 1910.1025 requires (plain English)
29 CFR 1910.1025 is OSHA's general-industry lead standard: the parent rule that protects workers in continuous lead operations such as battery manufacturing, secondary lead smelting, foundries, radiator repair, and the production of lead pigments and compounds. Lead is a cumulative poison that damages the nervous system, kidneys, blood, and reproductive system, and because the harm builds silently over time, the standard controls both the lead in the air a worker breathes and the lead that accumulates in their blood. It sets a permissible exposure limit of 50 µg/m³ as an 8-hour TWA and an action level of 30 µg/m³.
The program is comprehensive. Where exposures reach the action level, the employer must conduct exposure monitoring and provide medical surveillance, including periodic blood-lead and zinc protoporphyrin testing. Above the PEL, the employer must use feasible engineering and work-practice controls (ventilation, enclosure, housekeeping with HEPA vacuuming, not dry sweeping or compressed air) and supplement with respiratory protection, protective clothing, and hygiene facilities including change rooms and showers to prevent workers from carrying lead dust home. A written compliance program ties the controls together.
The standard's signature protection is Medical Removal Protection (MRP). When a worker's blood lead level is too high (generally at or above 60 µg/dL, or a three-test average of 50 µg/dL or more) the employer must temporarily remove the worker from lead exposure while preserving their earnings, seniority, and benefits (for up to 18 months). The worker may return only after two consecutive tests show a blood lead level below 40 µg/dL. This ties enforcement to the worker's actual absorbed dose, not just air readings, and removes the financial incentive to conceal high exposures. The construction counterpart, 1926.62, extends these protections to construction with an added "trigger task" framework.
