VHF - Dress-out Doffing and removal of CPC

Once we have reached the point where the patient has become momentarily stable, the patient care worker can decontaminate, and dress-out or “Doff” his/her CPC for a break or for a treatment worker rotation. To do this, last month’s step of decontamination inside the treatment/isolation area is completed and the worker can now move out of this zone. In traditional format, realize that the care worker would technically be now moving into the “Warm” zone of decontamination. After gross (or heavy) contamination is reduced the worker leaves the Hot Zone.

Many different formats can be employed that are particular to your location, equipment, isolation wards, etc.  But almost everyone can use the simplest and effective of waste handling procedures for infectious waste materials. Have your worker leave the hot zone and step into a large sized bio-hazard waste bag.

At this point, the concept is to leave all contaminated CPC inside this waste bag. So, respiratory protection will need to have been pre-evaluated for your desired result. If you choose re-useable long wearing full face APRs’ (recommended), a separate container will be needed for further decontamination before the APR is returned to its user. While this affords additional personnel/practices in your hazardous waste/laundering team, it does provide better personnel protection. The waste team will need full previously discussed CPC protection to decontaminate fully, the used APRs’ on or off-site depending on your facility plan for this type of incident.

After this step has been provided for, the worker must spray its’ inner gloves with bleach solution from another 1:100 spray bottle. The health care worker can then remove their level “B/C” protective suit into the bottom of the bio-hazard bag. IMPORTANT: the inner gloves will be removed as the final portion of the suit is stepped out of and the wearer MUST not touch the inner surfaces of the “B/C” protective CPC. Liken this to peeling a banana without touching the inside fruit. This is a procedure known as “Dry Decon” and requires separate team instruction and practice.

Once the CPC suit has been successfully “peeled” down to the bottom inside of the bio-hazard bag, the remaining protective clothing and or respiratory protection can be removed. You individual techniques are dependent upon the CPC/PPE chosen and accepted by your facility. Separate techniques in training with a practiced professional should be taken by your facility to make sure personnel can perform these tasks to remain contamination free.

When all these steps are successful, the patient care worker can now step out of the bio-waste bag into the “cold/clean zone”. At this point the waste/laundry team should move in and secure the bio-hazard waste bag as out-lined in the incineration steps for safe securement of VHF infected waste. It can then be transported to the waste team staging or processing area.

The health care worker should then move to the secured locker room area. Inner scrubs should be deposited into an additional bio-hazard waste bag that will be secured as previously mentioned and sent to the laundry to be processed by the waste team.

The health care worker should now body shower and dry off with a clean towel. He/she can now safely re-dress in “new” scrubs and footwear to return to the hospital area or break room. All workers must wash their hands before leaving the locker room.

Next month we shall continue on with the VHF of a mortuary team for large scale pandemics.
