NOTE: NuAire does not offer any product warranty with respect to cleaning material compatibility. USE AT YOUR
OWN RISK! The information provided above is from raw material suppliers and known general source documents
for use to develop application cleaning SOP’s.
NOTE: When cleaning the work area for the first several times, the new metal surfaces may produce some dark
discoloration on the white cleaning wipes. Repeated cleaning will continuously reduce the amount of the
discoloration material on the cleaning wipes over time.
6.6 Hazardous Drug Decontamination Procedures
This procedure is intended to provide guidance following a spillage and/or periodic maintenance, testing or relocation of
the cabinet. Additional guidance can be provided by the CETA document CAG-005-2007 found at the CETA website:
www.CETAinternational.org.
6.6.1 Preparation
Prior to beginning decontamination activity, personnel should wear proper personnel protection equipment (PPE)
i.e. Tyvek
1
isolation gown, 2 pair of Nitrile gloves and a full-faced HEPA filtered respirator. All protective garments
should be contained in 4 mil plastic bags and labeled for disposal as chemotherapy waste after completion of the
procedure. For the purpose of this procedure, detailed procedures for cleaning a Class II LFBSC can be found in the
2006 ASHP Technical Assistance Bulletin ASHP Guidelines on Handling Hazardous Drugs 2 .
6.6.2 Procedure
a. Make sure that the cabinet remains in operational mode with internal blower on.
b. Open the hinged or sliding view screen and secure in the full open position.
With the view screen in the full open position, personnel protection
is compromised and a full faced HEPA filtered respirator must be worn.
c. Clean all readily accessible surfaces of the cabinet.
d. Remove perforated metal diffuser screen from the underside of the supply HEPA filter and place on the
cabinet work tray.
NOTE:
Depending on the model, the diffuser screen is secured to the cabinet by #8-32 screws or 1/4" - 20 acorn
nuts, 3 places. It is purposely a tight fit and is secured to the back wall with projecting thread-less studs.
e. Clean both sides of the perforated metal diffuser screen and remove it from the cabinet.
f. Lift the cabinet work tray, clean both sides and remove it from the cabinet.
g. Remove the front perforated grill, place on the cabinet floor and clean both sides.
Remove from cabinet.
h. Clean work tray supports.
i. Working from top to bottom, clean all inside surfaces of the cabinet.
Take care not to wet the HEPA filter.
If liquid has collected in the plenum drain, aspirate it using IV tubing into an evacuated container.
Label the evacuated container for disposal as chemotherapy waste.
j. Clean the plenum drain area and wipe dry.
k. If the cabinet requires maintenance and/or replacement of the HEPA filters, the operation should be
halted at this point to allow trained personnel to complete replacement of the HEPA and/or maintenance
action required.
6.6.3 Assembly
a. Replace front (if removed) grill.
b. Replace the work tray and carefully tighten the thumbscrews.
c. Replace perforated metal diffuser screen over the underside of the supply HEPA filter.
d. Wipe down all exposed surfaces of the work area with 70% isopropyl alcohol.
e. Prepare for aseptic operation.
