vacant , enclosed room , users must perform manual cleaning , disinfection , and drying of surfaces within the room , following product IFUs . Next , users should follow the HPV device IFU , which generally indicate to place the portable device in the room ; seal HVAC vents , cover smoke detectors , and open cabinets / drawers in the room ; place at least one chemical and biological indicator in the room ; exit the room ; seal all doors to the room using tape ; and place a hazard sign at the sealed room doors .
Once the room is prepared , the user initiates a HPV cycle on the device controller and uses the handheld hydrogen peroxide sensor to verify that there is no HPV leakage around the outer doors . Several hours later after the HPV cycle completes , the user returns , unseals the room doors and cracks one door open . They hold the handheld hydrogen peroxide sensor within the room to verify that the chemical concentration is less than one part per million prior to room entry . Once verified , they unseal HVAC vents , uncover smoke detectors , and close cabinets / drawers within the room . Finally , the user documents the results of chemical and biological monitoring . If needed , the user responds to failed chemical and biological indicators per facility protocol .
Why use UV and HPV devices in long-term care facilities ?
Supplemental disinfection technologies should only be used safely . Facilities should provide written protocols for each room that UV and HPV devices will be used , a list of any sensitive equipment that must be removed from the rooms , user training on the protocols , personal protective equipment that users should wear , and how users should respond to accidental UV and HPV exposure .
