OSHA Variances

A variance is official permission from OSHA for an employer to use a different method than a standard requires, or to get extra time to meet a new standard. It is not a loophole. The employer must prove that workers will be as safe as they would be under the rule, and workers have a voice in the process.

Types of variances

TypeWhat it does
Temporary varianceGives extra time to comply with a new standard when the employer can’t meet it by the deadline, for reasons like lack of materials, equipment or trained people. The employer must apply before the deadline, show it’s working to comply, and protect workers in the meantime. It’s time-limited and may be renewed only in limited cases.
Permanent varianceLets an employer use a different method that the employer proves is at least as safe as the standard. The employer must apply and OSHA must agree. It can be changed or revoked.
Experimental varianceAllows an employer to try a new idea that could improve protection, usually to help test it for future rules.
Other variancesSpecial rules can apply for national defense or similar situations.

Variances apply to a specific employer and worksite and for specific conditions. They are not general permission for everyone. The rules are in 29 CFR Part 1905. Details change, so check OSHA’s variance page.

How an employer applies

  1. The employer applies in writing to OSHA, explaining the standard, the alternative and the reasons.
  2. The application must describe how workers will be protected, including training, equipment and procedures.
  3. The employer must tell affected workers and give their representatives a copy of the application. Notice is posted where workers will see it.
  4. Workers or their union can ask for a hearing and comment on the proposal.
  5. OSHA reviews, may ask for more information or visit the site, then grants or denies the variance.
  6. If granted, the employer must follow the conditions. OSHA can inspect for compliance.

State-plan states handle variances through their own agencies, so ask your state office. See State Plans Overview.

Examples of why employers ask

Before seeking a variance, many employers first check whether the standard already allows what they want. See Reading a Standard and Construction Standards (1926).
