1-6 Safety
Ensure that everyone involved with the operation of the instrument has:
♦ Received instruction in general safety practices for laboratories
♦ Received instruction in specific safety practices for the instrument
♦ Read and understood all related MSDSs
! CAUTION Avoid using this instrument in a manner not specified by Applied Biosystems.
Although the instrument has been designed to protect the user, this protection can be impaired
if the instrument is used improperly.
Operating the computer correctly prevents stress-producing effects such as fatigue,
pain, and strain.
To minimize these effects on your back, legs, eyes, and upper extremities (neck,
shoulder, arms, wrists, hands and fingers), design your workstation to promote neutral
or relaxed working positions. This includes working in an environment where heating,
air conditioning, ventilation, and lighting are set correctly. See the guidelines below.
!
CAUTION MUSCULOSKELETAL AND REPETITIVE MOTION HAZARD. These hazards
are caused by the following potential risk factors which include, but are not limited to, repetitive
motion, awkward posture, forceful exertion, holding static unhealthy positions, contact pressure,
and other workstation environmental factors.
♦ Use a seating position that provides the optimum combination of comfort,
accessibility to the keyboard, and freedom from fatigue-causing stresses and
pressures.
– The bulk of the person’s weight should be supported by the buttocks, not the
thighs.
– Feet should be flat on the floor, and the weight of the legs should be
supported by the floor, not the thighs.
– Lumbar support should be provided to maintain the proper concave curve of
the spine.
♦ Place the keyboard on a surface that provides:
– The proper height to position the forearms horizontally and upper arms
vertically.
– Support for the forearms and hands to avoid muscle fatigue in the upper
arms.
♦ Position the viewing screen to the height that allows normal body and head
posture. This height depends upon the physical proportions of the user.
♦ Adjust vision factors to optimize comfort and efficiency by:
– Adjusting screen variables, such as brightness, contrast, and color, to suit
personal preferences and ambient lighting.
– Positioning the screen to minimize reflections from ambient light sources.
– Positioning the screen at a distance that takes into account user variables
such as nearsightedness, farsightedness, astigmatism, and the effects of
corrective lenses.
