What's New at OLPPP?

California's revision of the occupational lead standards

The Cal/OSHA lead standards are based on lead toxicity information that is now 40 years old. Updated research shows that chronic and low-level lead exposures that are allowable under the current standards are harmful to adults. Revising the Workplace Lead Standards: At-A-Glance (PDF) gives an overview of the revision process as well as CDPH's recommendations.

There are 20 steps involved in developing an occupational health standard. You can follow the progress of the new lead standards on the Department of Industrial Relations website.
