Understanding Cal/OSHA's Lead Exposure Requirements for Construction

Lead exposure remains a significant health risk in the construction industry, and California's Occupational Safety and Health Administration (Cal/OSHA) has implemented stringent regulations to protect workers. These requirements, outlined in Title 8, Section 1532.1 of the California Code of Regulations, went into effect on January 1, 2025, with further restrictions planned for 2030.

Key Requirements for Lead Safety in Construction

1. Exposure Assessment
   Employers must assess workers' exposure to lead, particularly during activities like abrasive blasting. Until an assessment is completed, dry abrasive blasting is limited to five hours per day, dropping to two hours per day in 2030.
2. Permissible Exposure Limits (PEL)
   The current PEL for airborne lead is 25 micrograms per cubic meter of air. This limit will be reduced to 10 micrograms per cubic meter starting in 2030.
3. Protective Measures
   Employers must implement engineering controls, administrative controls, and substitution methods to minimize lead exposure. Respirators may be required, and employers should refer to Table 1 of Section 5144 for guidance on respirator protection factors.
4. Medical Surveillance & Reporting
   Workers exposed to lead must undergo regular medical evaluations, including blood lead level testing. Employers are required to report medical surveillance results to employees.
5. Training & Compliance Programs
   Employers must provide lead hazard training and maintain a written lead compliance program that includes safe work practices, personal protective equipment (PPE), and hygiene protocols.
6. Workplace Hygiene & Facilities
   Employers must provide changing areas, washing facilities, and designated break areas to prevent lead contamination and take-home exposure.

Why These Regulations Matter

Lead exposure can cause serious health issues, including neurological damage, reproductive harm, and kidney disease. By enforcing stricter regulations, Cal/OSHA aims to reduce workplace illnesses and ensure safer working conditions for construction workers.
