Wisconsin does not have a federally approved occupational safety and health regulatory program for the state; therefore, private sector workplaces must comply with federal occupational safety and health standards.
Wisconsin's safety and health rules govern public sector (state and local government offices and operations) workplaces. The state has adopted the federal material handling rules by reference (SPS 332.50) and adopted its own rules that are stricter than federal rules for the segregation of incompatible materials.
The U.S. Department of Labor/Occupational Safety and Health Administration (OSHA) administers and enforces federal workplace safety and health requirements in private sector workplaces. The Wisconsin Department of Safety and Professional Services (DSPS) administers the state workplace safety and health rules for public sector workplaces.
Employers must provide the means to disconnect the power on any and all conveyor systems that pass through more than one room or from one working level to another, where exposed to contact.
Incompatible materials must be segregated to prevent accidental contact with each other that may result in fire, explosion, or toxic gas emissions.
