[Dsg-halla_gem] EEL 124 Clean Room update

[Marc Mcmullen]

Good Morning,

I just wanted to give an update on the status of the gowning area and clean room as we all try to pull together to get it back into shape.

There are boxes of disposable gowning supplies in the gowning area, with various sizes. Please do not reuse gowning.

Signage has been posted to ensure all users are informed to not reuse gowning, all gowning should be discarded at the end of a shift.

Hair nets and booties are in the supplies locker. Keeping these items in the locker will help keep the area clean.

All gowning should be put inside the trash can at the end of a shift.

The small waste bin is very useful, at the end of the day please put it outside the gowning room and it will be emptied by the Janitorial contractors.

Yesterday facilities management performed preventative maintenance on the air handling system for the clean room and air shower. In all 19 filters were changed, 9 of which are hepa-filters.

Users should only keep the roll up doors open long enough to move equipment in and out. This will reduce the recovery time for the system as it works to keep the particle count low. Signage has been posted on the roll up door near the pull chain.

I have requested facilities management to put these on a quarterly change out. With the hepa-filters changed as deemed by the system developed by facilities management.

Lastly, I have requested that the floor in the gowning area be stripped and waxed. I will send another update when this has been completed. We have also resumed the janitorial cleaning schedule which existed pre-MEDCON.
