State OSHA Plan Requirements
Federal OSHA isn't the only regulator in the country. Here's how state plans fit in, and why it matters for confined space compliance.
Federal OSHA Applies in Most States
Federal OSHA directly enforces 29 CFR 1926 Subpart AA and 1910.146 in states that don't run their own occupational safety program.
State Plans Can Be More Stringent
Roughly half the states (and some territories) run their own OSHA-approved State Plan. These must be at least as protective as federal rules, and sometimes add requirements on top.
Check Your State's Specific Rules
Employers should check their state-specific occupational safety agency for confined space requirements beyond the federal baseline before relying solely on federal text.
This course is designed around federal OSHA standards (29 CFR 1926 Subpart AA and 1910.146) unless otherwise stated. If you work in a State Plan state, confirm whether that state has adopted additional or different confined space requirements. See OSHA's official State Plans directory below.
