6.4 Ergonomics
Ergonomics, the study or accommodation of work practices is extremely important for proper cabinet usage and user
health and safety. An evaluation of normal work practices should be performed with each user when working in a cabinet.
Evaluation criteria should be at a minimum:
a. Proper user posture
b. Effective work zone layout for work practice
c. Vision or sightlines
For each of the above evaluation criterion, several work aids may be supplied to accommodate the user.
•
Ergonomic chair - A six-way articulating seat and back control for personalized adjustment to assure proper user
posture. Be sure feet are resting on the floor, chair foot support or footrest. Also be sure back is fully supported
with proper chair adjustments.
• Forearm/elbow support - The cabinet is provided with a non-metallic forearm support on the work access opening.
Periodic mini breaks during work practice should be taken resting forearm to avoid stress and fatigue. Elbow rests
are optional that can provide support for particular work practices, such as pipetting. Also available as an option,
closed cell foam disposable forearm pads to reduce pressure points and add comfort.
•
Effective workzone layout - Always prepare your work procedure to minimize reach to avoid neck and shoulder
stress and fatigue. Rotating tables are optional to maximum workzone and minimize reach.
•
Vision and sightline - Always prepare your work procedure to eliminate glare and bright reflections on the window.
Keep your window clean and sightlines clear to your effective work zone.
6.5 Cleaning Procedures
6.5.1 General
Cleaning laboratory equipment is important in terms of both functionality and general good housekeeping. The
information provided below is intended to aid the development of facility Standard Operating Procedures (SOP’s)
for cleaning the equipment. It is strongly recommended that all cleaning materials used be tested and verified in
terms of both effectiveness and material compatibility before they are written into the cleaning SOP
documentation.
a. The airflow blower should be operating during the cleaning process to maintain sterility and/or containment
during the cleaning process.
b. Raise window to gain additional access if desired.
c. Apply appropriate cleaning material or surface disinfectant to surfaces. Most surface disinfectants require a
specific contact time depending the materials used within the work zone.
CONSULT APPROPRIATE DISINFECTANT
DOCUMENTATION FOR PROPER APPLICATION AND SAFETY PRECAUTIONS .
c-1. Stainless steel (type 304) has noted material compatibility concerns with Acids, Chlorides and Halogens. IF
THESE MATERIALS ARE USED AND ALLOWED TO BE LEFT ON THE STAINLESS-STEEL SURFACE, OXIDATION AND
DEGRADATION WILL OCCUR . Only by re-wiping surfaces with either sterile water or 70% IPA will remove harmful
materials from the stainless-steel surface.

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.
