Why Wyoming Is Different
Wyoming operates its own OSHA-approved State Plan, administered by Wyoming OSHA under Wyoming Rules and Regulations, Chapter 8; Wyoming Occupational Health and Safety Act. This means Wyoming doesn't just follow federal OSHA — it sets and enforces its own workplace safety standards that can be stricter than federal minimums.
For Electrical Contractors operating in Wyoming, this means you need to meet Wyoming-specific requirements, not just the federal baseline. Wyoming OSHA conducts its own inspections, issues its own citations, and sets its own penalty amounts.
Wyoming requires 1 additional program beyond federal OSHA that directly affect Electrical Contractors.
Penalty Snapshot
- Serious violation: up to $16,550 per citation
- Willful/repeat violation: up to $165,514 per citation
- Criminal penalties: Handled at federal level
- Wyoming adopts federal penalty schedule — cannot exceed federal penalty levels by statute.
Top Hazards for Electrical Contractors
Electrical contractors have the highest electrocution fatality rate of any construction trade. OSHA prioritizes electrical inspections on active construction sites.
- Electrocution and electrical burns (29 CFR 1926.405) — Electrocution is one of OSHA's "Fatal Four" in construction. Working on or near energized circuits without proper lockout/tagout is the leading cause.
- Arc flash exposure (NFPA 70E / 29 CFR 1926.407) — Arc flash can reach 35,000°F. Electrical contractors must perform arc flash risk assessments and provide appropriate PPE rated for incident energy levels.
- Falls during overhead work (29 CFR 1926.501) — Electrical work frequently requires ladder and scaffold use. Falls during panel installation, conduit runs, and overhead wiring are a leading injury cause.
- Lockout/tagout failures (29 CFR 1910.147) — Failure to de-energize and lock out circuits before service work. Every electrical contractor needs written LOTO procedures for each type of equipment serviced.
- Confined space entry (29 CFR 1926.1200) — Electrical contractors often work in vaults, manholes, and transformer rooms classified as confined spaces requiring permits, atmospheric testing, and rescue plans.
Most-cited violations for Electrical Contractors: Electrical wiring methods (1926.405), lockout/tagout (1910.147), fall protection (1926.501), PPE (1926.95), and hazard communication (1910.1200)

Key Regulatory Differences from Federal OSHA
- Statutory Limitation: Wyoming OSHA CANNOT adopt standards MORE STRINGENT than federal OSHA — prohibited by Wyoming Occupational Health and Safety Act. All federal standards are adopted identically. Unique state standards only exist where NO federal equivalent exists (oil & gas).
- Fall Protection Threshold: 6 feet — identical to federal
- Injury Reporting: Identical to federal: fatality within 8 hours, hospitalization/amputation/eye loss within 24 hours
- Contractor Licensing: No statewide contractor license required. Some municipalities (Jackson, Cheyenne, Casper) have local requirements.
- Oil Gas Rulemaking: Wyoming proposed new oil & gas rules in June 2025 (public comment period). Monitor for final rules — may affect oil_gas_wy program block.
- Posting: Wyoming OSHA poster required in addition to federal OSHA poster
