Health Effects of Low-level Lead Evaluation External). Reference blood lead level for adults. In 2015, NIOSH designated 5 µg/dL (five micrograms per deciliter) of whole blood, in a venous blood sample, as the reference blood lead level for adults. An elevated BLL is defined as a BLL ≥5 µg/dL.

The required (OSHA) Permissible Exposure Limit (PEL) action level for lead in general industry and the construction industry is a Time Weighted Average of 30 µg/m 3 over 8-hours. Some studies suggest that the current OSHA PEL and NIOSH REL may be too high to protect against certain health effects. 1, 2. Information on OSHA Lead Standards.

Apr 19, 2017 · Upon completion of this section, you will be able to identify the CDC�s level of concern for lead in children�s blood, identify the OSHA blood lead level for first intervention from occupational exposure to lead and describe the types of environmental standards in the U.S.

Blood lead levels can rise quickly. With frequent monitoring of blood lead levels, dangerous exposures can be quickly identified and corrected, workers can be protected, and the need for OSHA mandated medical removal of workers can be avoided. A blood lead level over 25 µg/dL shows that substantial exposure to lead is occurring.
