California Machine Guarding laws & safety compliance analysis

California Machine Guarding: What you need to know

California has adopted its own safety rules for machine guarding, with some additional standards not covered by federal rules. In a few cases, state rules are stricter than corresponding federal rules. The requirements are very detailed, and employers operating machinery subject to guard requirements should review the text of the applicable regulations to ensure full compliance. The state standards must be at least as strict as the federal standards; otherwise, the federal standards apply. Cal/OSHA administers and enforces workplace safety and health requirements in California.
