Wyoming State Plan

[Wyoming State Plan Website]

The Wyoming Occupational Safety and Health Administration (Wyoming OSHA) is part of the Wyoming Department of Workforce Services. The main office is located in Cheyenne, Wyoming.


The Wyoming State Plan applies to all state and local government and private sector workplaces in the state, with the exception of federal workers (including those employed at Yellowstone and Grand Teton National Parks), the United States Postal Service, private sector maritime, employment at Warren Air Force Base and at the Naval Petroleum and Oil Shale Reserve in Casper, and certain agricultural operations (field sanitation and temporary labor camps) which are subject to OSHA jurisdiction.

Unique State Plan Standards and Regulations

Wyoming OSHA adopts all federal standards identically except for 1910 Subparts A, B, and C, and 1926 Subparts A and B, which have been reworded to reflect the Wyoming Safety Act. New standards are promulgated by the State of Wyoming within six months of promulgation by the Secretary of Labor. Wyoming cannot adopt standards that are more stringent than corresponding federal standards, but can adopt standards for industries not covered by OSHA.

Wyoming has adopted the federal recordkeeping and reporting requirements identical to the federal rule; Wyoming has unique standards that cover Oil and Gas Well Drilling, Servicing, Special Servicing, and Anchor Tester Requirements. OSHA does not have specific standards for this industry. Wyoming has a unique Child Labor standard.

Enforcement Programs

Wyoming OSHA Compliance is responsible for the enforcement of the Wyoming OSHA safety and health standards. The Wyoming Rules of Practice and Procedure provide guidance for both the enforcement and consultation programs. Compliance officers inspect workplaces for hazardous conditions and issue citations where violations of Wyoming OSHA regulations are found. Inspections may be the result of: regular scheduling, imminent danger reports, fatalities, employee complaints or referrals. Inspections in Wyoming are scheduled for high hazard industries using worker compensation rates or through Local Emphasis Programs or the University of Tennessee Dodge Report System. More information on enforcement in Wyoming can be found on the Wyoming State Plan website.

Voluntary and Cooperative Programs

Wyoming offers free safety and health assistance to Wyoming employers upon request through the voluntary On-Site consultation program. Consultation services include safety and health program assistance, courtesy on-site hazard surveys, and safety and health training on a variety of subjects covering general industry, construction, and the oil and gas industry. For more information about these programs and other services available, please visit the Wyoming State Plan website.

Informal Conferences and Appeals

Informal conferences are conducted in the Wyoming OSHA office in an effort to resolve contested cases. Contested cases not resolved by informal conference are referred to the Office of Administrative Hearings (OAH), which is an independent state agency. The OAH hearing officer then recommends a decision to the Occupational Safety and Health Commission. The Commission makes the final decision concerning contested cases. If appealed by either party, the contested case will move to the District Court and then to the state's Supreme Court if not resolved.
