From page 3... ... An employee may resume work associated with lead exposure only after two BLLs are lower than 40 µg/dL. Thus, maintaining BLLs lower than 40 µg/dL was judged by OSHA to protect workers from adverse health effects. Read the entire page →
From page 4... ... To address its charge, the committee focused on determining whether there is evidence of adverse health effects in people who have BLLs of 40 µg/dL or lower because that is the implicit level in the OSHA standard to protect workers from adverse health effects; indeed, the standard allows workers to have a BLL up to 40 µg/dL for a 40-year working lifetime. The committee also considered measures of cumulative lead dose. Read the entire page →
From page 5... ...  Adverse nervous system effects include dose-related changes in cognitive and psychomotor performance at a BLL of about 18 µg/dL and such neurophysiologic changes as hearing loss at BLLs under 10 µg/dL, changes in balance at BLLs of about 14 µg/dL, changes in visual function at BLLs of 17-20 µg/dL, slowed auditory evoked potentials at BLLs of 26-30 µg/dL, changes in autonomic function at BLLs over 20 µg/dL, and changes in peripheral sensory nerve function at BLLs around 30 µg/dL.  Adverse hematologic effects include impaired formation and impaired survival of erythrocytes at BLLs of about 20-30 µg/dL.

From page 6... ... However, data on airborne concentrations of lead on DOD firing ranges indicate that the current OSHA PEL is exceeded in the performance of some job duties, in some cases by several orders of magnitude, and this may lead to increased BLLs. Thus, DOD should consider analyzing BLLs of a representative sample of range workers in all the services and comparing them with BLLs linked to adverse health outcomes to understand potential health risks and to guide riskmanagement decisions at its ranges. Read the entire page →
From page 7... ... Summary 7 The results of the analyses will help to inform decisions about setting new air exposure limits for lead on firing ranges, about whether to implement limits for surface contamination, and about how to design lead-surveillance programs for range personnel appropriately.
