Safety
The following pages describe common practices concerning electrical safety,
ergonomics, rack installation, and electrostatic discharge.
WARNING:
Potential injury: On-the-job safety is important; therefore, observe the
following safety precautions. Failing to follow these precautions could
result in serious injury.
Remove all conductive jewelry, such as watches and rings, before you
access CRUs.
• Avoid electrical shock. Be careful when you work near power connectors
and supplies.
• Power-off the equipment before you remove a customer replaceable unit
(CRU). Remember that dangerous voltages could still be present in some
areas even though power is off.
• Lift objects properly; read the information in “Lifting Techniques.”
• Enforce good housekeeping practices in the equipment area to help prevent
fire and accidents.

Lifting Techniques
Lifting, regardless of how much or how little, can create serious back stress. If
you follow these guidelines, you can reduce the risk of back injury:
• Do not twist your body to pick up something or to put it down. Twisting
puts extreme pressure on your back, especially when you lift or carry
objects. Instead of twisting, make the task two separate moves; first lift, and
then use your feet to turn your body.
• Plan the lift: first examine the object and then determine how it will be
lifted and where it will be placed.
• Choose the appropriate lifting technique. Examine the weight, size,
location, frequency, and direction of the lift. Plan to avoid awkward
postures, and determine if material-handling aids are needed.
• Place your feet shoulder-width apart, and place one foot a little behind the
other. Keep your back straight because even light loads can significantly
increase pressure on your spine when you lean forward.
