Section 5 Cleaning and Maintenance
5-1
5.1. Preparation and Best Practice
Cleaning is the necessary first 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
interfere with microbial inactivation. The physical action of scrubbing with detergents and surfactants and
rinsing with water removes substantial numbers of microorganisms. If a surface is not cleaned first, 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 the 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 chair 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
5.2. Standard Vinyl Upholstery Cleaning and Disinfecting
The manufacturers of the upholstery materials used on the Maxi SMR S 4000 and S 4500 chairs recommend the following
cleaning methods:
For Light soiling:
A solution of 10% household liquid dish soap (pH~9) with warm water applied with a soft damp cloth will remove most
soiling.
NOTE
!
Clean and disinfect after every patient according to CDC and OSHA requirements
for non-critical devices.
WARNING
!
DISCONNECT ALL ELECTRICAL POWER PRIOR TO CLEANING AND
DISINFECTING. RISK OF ELECTRICAL SHOCK RESULTING IN DEATH OR
INJURY IS POSSIBLE IF THE ELECTRICAL POWER IS NOT DISCONNECTED.
WARNING
!
DO NOT CLEAN ANY SURFACE WITH PETROLEUM-BASED SOLVENTS
SUCH AS ACETONE OR M.E.K. (METHYL ETHYL KETONE). THESE
SOLVENTS WILL REMOVE PAINT AND CAUSE PERMANENT DAMAGE TO
VINYL AND PLASTIC SURFACES. USING THESE SOLVENTS ALSO PRES
-
ENTS A DANGER TO PERSONNEL IF THEY ARE OPENED IN A POORLY
VENTILATED ROOM.
CAUTION
!
DO NOT Use scouring materials such as SCOTCH-BRITE® on vinyl or plastic
surfaces for stubborn stains. These materials will damage these surfaces.
CAUTION
Do not allow excessive moisture or liquids to come in direct contact with the
unit.
NOTE
!
Do not allow cleaning agents or liquids to enter the power input.
NOTE
!
When cleaning and disinfecting the chair, wear puncture and chemical-resistant gloves
and other PPE to prevent occupational exposure to infectious agents and hazardous
chemicals
