5.1. Cleaning and Disinfecting
5.1.1. Preparation and Best Practice
Cleaning is the necessary rst step of any disinfection process. Cleaning is a form of decontamination that
renders the environmental surface safe by removing organic matter, salts, and visible soils, all of which inter-
fere with microbial in activation. The physical action of scrubbing with detergents and surfactants and rinsing
with water removes substantial numbers of microorganisms. If a surface is not cleaned rst, the success of the
disinfection process can be compromised. Removal of all visible blood and inorganic and organic matter can
be as critical as the germicidal activity of a disinfecting agent.
Clean and disinfect clinical contact surfaces by using an EPA-registered hospital disinfectant with a low-level
activity (i.e., HIV and HBV label claims) to intermediate-level activity (i.e., tuberculocidal claim) after each
patient. Use an intermediate-level disinfectant if the cabinet is visibly contaminated. In addition, cleaning and
disinfection are recommended at the end of daily work activities and are required if surfaces have become
contaminated since their last cleaning.
Follow the instructions given by the manufacturer of the disinfectant solution, however:
• Apply disinfectant per the manufacturer’s instructions. Ensure that instructions for contact time are adhered
to.
• After appropriate contact time, remove cleaning solution residue by wiping all surfaces with a clean soft
cloth or lint-free tissue lightly moistened with distilled water.
• Dry as necessary.
5.1.2. Disposable Items
The vacuum tubing, lters, canisters and canister liners are disposable. Cleaning and disinfection are not
recommended.
NOTE
!
See the table 5-2 “Maintenance Activity Schedule” for frequency of changing the disposable
components.
WARNING
ELECTRICAL SHOCK HAZARD! DISCONNECT ALL ELECTRICAL POWER PRIOR
TO CLEANING AND DISINFECTING.
CAUTION
!
DO NOT ALLOW EXCESSIVE MOISTURE OR LIQUIDS TO COME IN DIRECT
CONTACT WITH THE UNIT.
CAUTION
!
DO NOT CLEAN ANY SURFACE WITH PETROLEUM-BASED SOLVENTS SUCH
AS ACETONE OR METHYL ETHYL KETONE (M.E.K.), OR SALTY ACIDS SUCH AS
HCL. THESE SOLVENTS CAN REMOVE PAINT AND CAUSE PERMANENT DAMAGE
TO PLASTIC SURFACES. USE OF THESE CLEANING AGENTS IN A POORLY
VENTILATED ROOM OR IF HANDLED IMPROPERLY, PRESENTS A DANGER TO
INDIVIDUALS.
NOTE
!
Do not allow cleaning agents or liquids to enter the power input.
NOTE
!
Clean and disinfect after every patient according to CDC and OSHA requirements for
noncritical devices.
NOTE
!
When cleaning and disinfecting the cabinet, wear puncture and chemical-resistant gloves
and other PPE Tto prevent occupational exposure to infectious agents and hazardous
chemicals.
