Housekeeping - Protective coverings for equipment and environmental surfaces.

1910.1030(d)(4)(ii)(B)
"Protective coverings, such as plastic wrap, aluminum foil, or imperviously-backed absorbent paper used to cover equipment and environmental surfaces, shall be removed and replaced as soon as feasible, when they become overtly contaminate or at the end of the work shift if they may have become contaminated during the shift."

"Relative to changing such coverings between patients, it should be remembered that, while this is prudent infection control practice which the Agency supports, OSHA's mandate is to protect employee health. Therefore, changing between patients has not been required as it falls into the realm of patient protection....more stringent decontamination rules that may be imposed to further infection control are not preempted."
