c. Workers shall have access to labels on containers of lead and safety data sheets, and must be trained as per 5194 and 1532.1, 1532.1(l)(1)(A).

d. The employer shall implement a written compliance program to control hazardous lead exposures. 1532.1(e)

e. The employer shall provide the worker with and require the use of appropriate personal protective equipment. 1532.1(f), (g)

f. The employer shall ensure that all protective clothing is removed at the completion of a work shift only in change areas provided for that purpose. 1532.1(g)

B. The permissible exposure limits (PELs) for airborne lead are 0.05 milligrams per cubic meter of air (mg/m3) and an action level of 0.03 mg/m3, both as an 8-hour time-weighted average (TWA). 1532.1(b)(c)

C. Trigger tasks are certain highly hazardous tasks that carry the presumption of airborne exposure above the PEL. They require special protective measures until it is determined that worker airborne exposures to lead are below levels specified in 1532.1.

Following are the three levels of trigger tasks (as provided in Cal/ OSHA’s “Lead in Construction” fact-sheet [https://www.dir.ca.gov/dosh/dosh_publications/lead-fct-sheetrev.pdf]) involving lead-containing materials and their associated respirator requirements: 1532.1(d)(2)

2. Level 2 trigger tasks: Using lead-containing mortar; burning lead; rivet busting; cleaning power tools without a dust collection system; using dry, expendable abrasives for clean-up procedures; moving or removing an abrasive blasting enclosure.

• Minimum respirator r equirement: A full respirator with N100, R100, or P100 filters; a supplied-

2. Clothing change areas and a shower.

4. Basic lead hazard, respirator, and safety training.

5. The employer shall post the following warning signs in regulated area or work area where an employee’s exposure

DO NOT EAT, DRINK OR SMOKE IN THIS AREA

Note: The above protective requirements must be enforced until worker airborne exposures are shown to be below levels specified in 1532.1.

E. Blood lead monitoring is especially important work

F. Employer shall notify an employee whose blood lead level is at or above 40 μg

Note: Many physicians are now choosing to place employees on medical removal protection at blood lead levels above 20 $ \mu\mathrm{g}/\mathrm{d l} $ , rather than 50 $ \mu\mathrm{g}/\mathrm{d l} $ . Thus, employers should target for the 20 $ \mu\mathrm{g}/\mathrm{d l} $ level as they evaluate the BLL results.
