Abstract This permanent standard dated 8 Nov. 1978 (effective: 1 Feb. 1979) establishes a permissible exposure limit of 50µg/m3 averaged over 8h, or (for exposure exceeding 8h) a time-weighted average determined as: the maximum permissible limit (in µg/m3) = 400/hours worked during a 24h period. The standard contains provisions concerning; monitoring, respiratory protection for lead aerosols, respirator selection, protective clothing and equipment, cleaning of floors and other surfaces, vacuum cleaning, hygiene facilities and practices, changing rooms, medical surveillance (biological monitoring, blood sampling tests and medical examinations, restrictions on chelation, transfer of workers to other employment), worker training and information, warning notices. The text of the standard is preceded by supplementary and background information, and the attachments to the preamble contain general information on lead toxicity, industry surveys (smelting, refining, scrap handling, battery breaking), feasibility and compliance cost predictions.
