California's workplace safety framework does not begin and end with SB-553 or even with the IIPP. Many California employers face additional hazard-specific compliance obligations and mandatory training programs that fall outside the workplace violence statute entirely — and a defensible compliance posture has to account for all of them.
Beyond the IIPP, many California employers face hazard-specific compliance obligations that apply based on industry and workplace conditions rather than headcount. Heat Illness Prevention is required for any employer with outdoor workers exposed to heat. Hazard Communication (SDS, labeling, employee training) applies wherever employees may be exposed to hazardous chemicals. Lockout/Tagout, Bloodborne Pathogens, Respiratory Protection, and Powered Industrial Trucks are triggered by the specific conditions present. Each has its own written program, training, documentation, and recordkeeping requirements.
California also requires mandatory harassment prevention training — separate from OSHA obligations — for all employers with five or more employees. Supervisors must complete two hours of training every two years under AB 1825. Non-supervisory employees must complete one hour every two years under SB 1343. This is not a Cal/OSHA requirement, but it is a mandatory, recurring, and documented training obligation that most California employers manage alongside their safety program.
