桠 † Always ensure that your legs have enough legroom.
桠 † Keep your lower back comfortably supported by your chair. Adjust the chair or use an appropriate
support (e.g. pillow) behind your back whenever necessary.
桠 † You should place your feet flat on the floor or on a footrest. Don't dangle your feet and compress
your thighs.
桠 † You should vary your sitting position throughout the day at regular intervals so that you are never in
the same posture for too long.
桠 † Observe the following precautions with respect to your eyes:
1 † Give your eyes frequent breaks. Periodically look away from the work area and focus at a
distant point.
1 † Keep your glasses clean.
桠 † Arrange the items/apparatus frequently used in your work in such a way that you can minimize the
physical strain involved in handling them.
桠 † Exercise regularly.

4.5.桠 UV Lamps (If Present)
Shortwave UV (UVC) is considered as germicidal and virucidal. The UV lamp that Esco provides has a large
portion of the spectrum in the UVC range. Unlike many other types of decontamination agent, UV light does
not leave any residue. The decontamination action stops upon de-energizing of the lamp. However, the UVC
spectrum does not penetrate well.
桠 † UV light decontamination method may be used before and after working with susceptible organisms.
However, it should not be the sole decontamination agent. Chemical decontamination agent should
still be used.
桠 † There should be minimal amount of material inside the BSC's work area during the process of UV light
decontamination. A direct interaction with UV light can degenerate plastic or rubber-based material
and can cause other hazards (e.g. Generation of hazardous vapors).
桠 † Before activating the UV lamp, the BSC sash should be in fully closed position and the user should
ensure that interlock is working properly. Avoid direct contact with skin and eyes as UV light is
classified as a probable human carcinogen.
桠 † The UV timer feature should be used to easily control the decontamination period (Note: UV timer is
60 minutes by default). Leaving the UV lamp on for over 60 minutes or even overnight is not
recommended because it shortens the lifespan of the lamp. The UV lamps used in Esco BSCs have a
lifespan of 2,000 hours.
桠 † The UV lamp should be cleaned of any dust and dirt weekly and changed annually to ensure its
effectiveness. Ensure that the lamp is turned off when lamp cleaning and maintenance is carried out.
桠 † Please note that the use of UV lamp in a BSC has been explicitly discouraged in all major international
standards and recommendations.
4.6.桠 Decontamination and Disinfecting Agents
桠 † For stainless steel surfaces, all common disinfectant agents, except chlorine-based ones, are suitable.
Where chlorine-based agents are used, sterile water should be used to wipe down the surfaces
following the application of the disinfectant agents.
桠 † For powder coated surfaces, all common disinfectant agents are suitable. However, the BSC has been
specifically evaluated for use with the following:
