​​​​Recommendations for Improving the Cal/OSHA Lead Standa​​​rds

The Cal/OSHA lead standards are based on lead toxicity information that is now 40 years old. Current medical information clearly demonstrates harmful effects of chronic and low-level exposures to lead in adults, at levels well below those currently allowed by the standards.

The CDPH Occupational Lead Poisoning Prevention Program (OLPPP) reviewed the scientific information and made health-based recommendations to Cal/OSHA for revising its General Industry Lead Standard and Construction Industry Lead Standard for the protection of workers who are exposed to lead on the job. OLPPP participated in the Cal/OSHA (Division of Occupational Safety and Health) Advisory Committee process for revising the Lead Standards. See below for details and supporting documentation.

Calif​orn​ia L​​ead Le​​gisl​​​​​ation & Regulations

The California State Legislature creates legislation (laws) through the passage of Assembly or Senate bills.

Regulations, also referred to as "standards," are the details and requirements for a given law.

Health standards are proposed by State agencies, such as the California Division of Occupational Safety and Health (Cal/OSHA) in the California Department of Industrial Relations, through a rulemaking process. Although Cal/OSHA proposes health regulations (and enforces health and safety regulations), they are passed by the California Occupational Safety and Health Board whose members are appointed by the Governor.

The following is a list of California occupational lead poisoning prevention laws and regulations.

Recom​​me​ndations for improving the Cal/OSHA Lead Standards

The Cal/OSHA lead standards are based on lead toxicity information that is now over 40 years old. Current medical information clearly demonstrates harmful effects of chronic and low-level exposures to lead in adults, at levels well below those currently allowed by the standards. See OLPPP's Recommendations for Improving the Cal/OSHA Lead Standards.


Lead in the Workp​lace - The New Science

A one-day scient​ific symposium moderated by John Howard, MD, Director of NIOSH

The CDPH Occupational Lead Poisoning Prevention Program (OLPPP) has reviewed available scientific information and made health-based recommendations to Cal/OSHA for revising its General Industry Lead Standard and Lead in Construction Standard. This symposium, held on November 13, 2013, discussed the scientific basis for the CDPH recommendations.

Scientific experts provided detailed presentations on the current literature on health effects of low-level lead exposure and the Cal/EPA report on modeling of the air lead/blood lead relationship. A CDPH representative presented the basis for the CDPH's Permissible Exposure Limit (PEL) recommendation (PDF) to Cal/OSHA. In addition, a panel of experts from related disciplines responded to the presentations and participated in a Q & A session with symposium attendees.​
