VHF - 12 "Doffing" procedures for Dress-out and Decontamination

To collectively reach the phase of your incident where final disinfection/decontamination takes place and removes the patient treatment personnel from the Hot Zone involves two (2) concepts;

1] Technical Decontamination

2] Disinfection BEFORE removal

Technical decontamination first involves the removal of major or heavy volumes of projectile vomiting or other bodily fluid discharge from the patients which have contaminated the health care worker. These volumes must be wiped off as completely as possible and treated in the previous months’ post with 1:10 bleach solution, soaked towels, and the listed time limits. Once this has been accomplished, technical decontamination blends into “disinfection before removal” both inside the isolation area (Hot Zone) and outside this zone depending on the operational set-up you decide will work best for your facility given the physical room limitations.

Disinfection BEFORE removal involves conditions where either the massive discharges did not occur, or have been mitigated as previously noted. Unless major projectile discharge occurs, or has been mitigated, the outer gloves and booties are likely to have the most contact with VHF agents and therefore the heaviest contamination (VHF fluids during patient care) at this point.

Ideally, before leaving the Hot Zone (isolation area/patient isolation room) the procedure must follow these steps;

1] After the final 3 to 5 minute soaking of gloves in the 1:100 bleach solutions, wash in a separate bin/sink the outer gloved hands with soap and water.

2] In a clean solution or “spray” dip or soak the gloved hands in a 1:100 bleach solution for one (1) minute.

3] Step into (or keep moist with a spray) a solution bin of 1:100 bleach solution enough to cover the outer soles of your footwear. The best way to accomplish this is to begin this procedure while these other processes are taking place. This way a longer time period will and should be realized for footwear. This is because additional contamination will be accumulated on the footwear. Therefore, a longer time period should be considered for footwear saturation.

4] While this is ongoing, spray the outer CPC garment with 1:100 bleach solutions. When the entire CPC has been covered with the spray solution outer decontamination has been completed. When finished,

5] Step out of the bin/pan onto one of your clean, bleach soaked towels to dry off more completely the CPC booties soles. This clean bleach soaked towel should have been previously placed inside a bio-hazard bag or waste transportable vessel of your choice.

6] While standing on this bleach soaked cloth, remove your outer booties, remove outer gloves, and slide this ensemble down around you and into the bio-hazard waste container IN THIS ORDER

7] Lastly; step out of this area into a clean area located outside the patient treatment isolation area (Hot Zone). Deposit remaining Inner gloves into a separate bio-waste container (bio-waste bag).

Personal hygiene should be managed at this point before laundering used inner clothing and re-showering before being released from the contaminated site area.
