However, sitting position has some drawbacks too:

The working area available is fairly limited

There is a potential risk of being constrained in the same posture for a long time

Sitting posture is one of the most stressful postures for one’s back
Therefore you should pay careful attention to the following guidelines in order to achieve comfortable and
healthy working conditions:

Always ensure that your legs have enough legroom.

Keep your lower back comfortably supported by your chair. Adjust the chair or use a pillow behind
your back whenever necessary.

You should place your feet flat on the floor or on a footrest. Don’t dangle your feet and compress
your thighs.

You should keep varying your sitting position throughout the day at regular intervals so that you are
never in the same posture for too long.

Observe the following precautions with respect to your eyes:
o
Give your eyes frequent breaks. Periodically look away from the work area and focus at a
distant point.
o
Keep your glasses clean.

Arrange the items/apparatus frequently used in your work in such a way that you can minimize the
physical strain involved in handling them.

Exercise regularly

3.5 UV Lamps
The UV light is a very effective germicide and virucide. Even at the minimum acceptable irradiance in a BSC –
40 μW/cm
2
(US Department of Health and Human Services et. al., 2000), it would only take 12.5 minutes to
reach 30,000 μW/cm2 (1 W = 1 J/sec), which has been listed as germicidal for spore forming organism.
Unlike many other type of decontamination agent, UV light doesn’t leave any residue. The decontamination
action stops upon de-energizing of the lamp.
However, due to the short wavelength, the UV light does not penetrate well. Thus UV light can only be used to
effectively disinfect the work area of an empty BSC. For any container stored inside the BSC’s work area, the
UV radiation will only disinfect the outer surface of the material, leaving the inner surface and the content
inside the material untouched.

UV light decontamination method may be used before and after working with vegetative organisms
and viruses. However, it should not be the sole decontamination agent; the use of chemical
decontamination agent is still encouraged.

Minimize the 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
hazard.

Make sure that the BSC sash is in the fully closed position and the interlock is working properly before
activating the UV lamp. Avoid direct contact with skin and eyes as UV light is classified as a probable
human carcinogen.

The UV lamp should be activated for around 60 minutes to work effectively. Use the UV timer feature
to easily control the period of decontamination (UV timer is disabled by default). Leaving the UV lamp
