Large workplaces would check air and improve ventilation

Employers would include systems to reduce air exposure and watch for related health effects in their written safety programs. This applies to employers with more than 15 employees at a facility of at least 10,000 square feet where employees face outdoor elements for most of each shift, if the employer must have a written safety program. The systems must meet applicable workplace safety standards. These rules would not apply to state agencies or employers engaged in law enforcement, firefighting, emergency response, solid or hazardous waste management, or towing.

Employers would require vehicles loading or unloading at the facility to turn off their engines. This applies at facilities of at least 10,000 square feet where employees face outdoor elements for most of each shift, for employers with more than 15 employees who must have a written safety program. A refrigerated vehicle or trailer may run a separate motor that powers refrigeration. The rule would not apply to state agencies or employers engaged in law enforcement, firefighting, emergency response, solid or hazardous waste management, or towing.

A designated person would check and record air readings, and the employer would use added ventilation if readings exceed a safety standard. This applies to employers with more than 15 employees at a facility of at least 10,000 square feet where employees face outdoor elements for most of each shift, if the employer must have a written safety program. The checks must cover each area where employees work, including elevated areas. Records must stay at the facility and be available for review upon request. These rules would not apply to state agencies or employers engaged in law enforcement, firefighting, emergency response, solid or hazardous waste management, or towing. Checks must happen at least every four hours while employees are working.
