Recently one of our LWMMI (League of Wisconsin Municipalities) insureds asked this question, "Are municipalities (and related entities) covered by OSHA?" and an issue of The Municipality, confirmed a response we initially provided...
"Local governments are not subject to state regulations, which are at least as stringent as OSHA, does not have jurisdiction over the state or local governments because the definition of "employer" under the OSHA Act of 1970 specifically excludes states and any political subdivision of a state."
"Instead, the State of Wisconsin has jurisdiction and the Wisconsin Statutes requires that the Department of Commerce adopt, by administrative rule, standards to protect the safety and health of public employees. These standards must provide protection at least equal to that provided to private sector employees under OSHA standards." - The Municipality (a publication of the League of Wisconsin Municipalities)
