The OSHA Lead Standards for General Industry (29 CFR 1910.1025) and Construction (29 CFR 1926.62) require employers to provide biological monitoring for workers exposed to airborne lead above the action level. Monitoring must be provided for lead and zinc protoporphyrin (or free erythrocyte protoporphyrin) in blood. The employer is required to have these analyses performed by a laboratory that meets accuracy requirements specified by OSHA.
The OSHA List of Laboratories Approved for Blood Lead Analysis is designed to provide a source for regulated employers to locate laboratories that OSHA has determined meet the requirements of the accuracy provisions of the Lead Standards. Laboratories voluntarily provide proficiency test data to OSHA for evaluation. The following chart illustrates the fact that not only has the number of participating labs increased, but that the rate of approval has also increased. This translates into better analytical service for regulated employers.
OSHA will make every effort to include those laboratories that have provided proficiency testing data and that currently meet the accuracy provisions for occupational blood lead testing. The list of approved laboratories is updated 3 times per year (approximately January, June, and September).
