What is Cal/OSHA?

Cal/OSHA, also known as the Division of Occupational Safety and Health (DOSH), protects California workers by creating and enforcing occupational safety and health standards. Cal/OSHA standards meet or exceed federal OSHA standards.

Cal/OSHA standards are outlined in Title 8 of the California Code of Regulations. These regulations apply to the vast majority of California employees, including local and state government workers.

Which Cal/OSHA standards apply to construction workers?

California construction employers must comply with a specific set of standards found in the following Cal/OSHA subchapters: Construction Safety Orders, Electrical Safety Orders and General Industry Safety Orders. Review the full list of these standards on Cal/OSHA's website.

How long will it take to complete the course?

To satisfy Cal/OSHA training requirements, construction supervisors must complete a 30-hour OSHA Outreach course with three hours of supplementary training on Cal/OSHA regulations.

Due to federal OSHA rules, you can spend no more than 7.5 hours per day in OSHA Outreach training. That means it will take a minimum of four days to complete your training. Time spent on Cal/OSHA topics does not count toward the 7.5-hour daily limit.

What is an OSHA 30 DOL card?

The U.S. Department of Labor (DOL) issues OSHA 30 cards to workers who complete 30 hours of OSHA Outreach training on industry-specific workplace safety topics. This wallet-sized card is printed on durable plastic and is accepted nationwide as proof of training.

Many construction employers in California require supervisors to earn an OSHA 30 card before starting work. Entry-level workers typically must complete 10 hours of Outreach training in order to earn an OSHA 10 card.
