Major Elements of OSHA’s Lead Standard. A permissible exposure limit (PEL) of 50 micrograms of lead per cubic meter of air, as averaged over an 8-hour period. Requirements that employers use engi-neering controls and work practices, where feasible, to reduce worker exposure.
Lead enters the body primarily through inhalation and ingestion. Today, adults are mainly exposed to lead by breathing in lead-containing dust and fumes at work, or from hobbies that involve lead. Lead passes through the lungs into the blood where it can harm many of the body's organ systems.

The Occupational Safety and Health Administration (OSHA) has permissible exposure limits (PELs) for hazardous materials. PELs are legal limits that are enforceable in workplaces. They are covered under the Occupational Safety and Health Act of 1970.
Lead is a naturally occurring, soft, bluish-gray heavy metal. Although nearly 50% of lead used today comes from recycled materials such as car batteries, its most common source is the mineral Galena (lead sulfide) that forms as pockets or veins in carbonate rock.
lead. You can be exposed to lead for months – or years – and not have any symptoms, but the longer you are exposed, the greater your risk of developing health problems. How does lead enter your body? There are two primary ways: You can breathe in lead from dust or fumes or you can swallow lead if it gets on your hands or
The Occupational Safety and Health Administration (OSHA) limits workplace airborne exposure to 50 µg/m3 (micrograms lead per cubic meter air) averaged over an 8 hour workday. (Extended work days must be compared to a modified exposure limit of 400 µg/m3 ÷ hours worked per day.)(29CFR 1910.1025; 1926.62)
OSHA has established two diferent lim-its for airborne exposure to lead [29 CFR 1910.1025*]. The action level for airborne lead exposure is 30 micrograms per cu-bic meter of air (μg/m3) as an 8-hour time weighted average (TWA). The OSHA PEL for airborne exposure to lead is 50 μg/m3 as an 8-hour TWA.
FACT SHEET. Lead in Construction. Title 8 California Code of Regulations (T8 CCR) section 1532.1 establishes required lead safety measures for construction employers. Implementing these measures, and following industry best practices, can reduce the risk of employee lead poisoning.
OSHA’s Lead Standard. OSHA’s Lead Standard for the Construction Industry, Title 29 Code of Federal Regulations 1926.62, covers lead in a variety of forms, including metallic lead, all inorganic lead compounds, and organic lead soaps.
