Provide showers and changing rooms.
(1) You must provide changing areas and showers outside a contaminated area, when needed for worker decontamination, that include at least the following:
(a) Separate changing areas:
(i) One to provide a clean area where employees can remove, store, and put on street clothing with an exit leading off the work site.
(ii) Another where employees can put on, remove, store, and dispose of work clothing and PPE with an exit leading to the work site.
(b) A shower area separating the changing areas.
(2) You must prevent clean areas from being contaminated by hazardous substances.
(3) You must provide and use other effective means for worker cleansing, if temperature conditions prevent the effective use of water.
(4) You must locate showers and change rooms where worker exposures are below permissible exposure limits (PELs) or other published exposure levels.
If this cannot be accomplished, use a ventilation system to supply air that is below the PELs or published exposure levels.
(5) You must make sure all workers shower at the end of their work shift or before they leave the site, when needed for worker decontamination.
