Oil and Gas Well Drilling, Servicing and Storage - Storage Tanks
There are twenty-eight OSHA-approved State Plans, operating state-wide occupational safety and health programs. State Plans are required to have standards and enforcement programs that are at least as effective as OSHA's and may have different or more stringent requirements.
This section highlights OSHA standards, directives (instruction to OSHA staff), letters of interpretation (official letters of interpretation of the standards) and national consensus standards related to the permit- and non-permit-required confined spaces in the petrochemical industry.
Frequently Cited Standards
OSHA maintains a listing of the most frequently cited standards for specified 6-digit North American Industry Classification System (NAICS) codes. Please refer to OSHA’s Frequently Cited OSHA Standards page for additional information. For Drilling Oil and Gas Wells and Support Activities for Oil and Gas Operations, use NAICS code 213111 and 213112 in the NAICS search box.
