Under 1905 Subpart B, what is a ‘variance’ and when would an employer seek one?
A variance is official OSHA permission to use a different method or time frame than the standard requires when compliance as written is not possible or would cause undue hardship. Under 1905 Subpart B, employers seek a variance when they cannot comply with a standard’s specific requirement but can demonstrate an alternative that assures equal or greater employee protection, or when they need more time to come into compliance.
