Safety Precautions
CAUTION:
Potential injury: On-the-job safety is important; therefore, observe the
following safety precautions while you are engaging in any maintenance
activity. Failing to follow these precautions could result in serious injury.
Remove all conductive jewelry, such as watches and rings, before you
service powered-on equipment.
• Avoid electrical shock. Be careful when you work near power connectors
and supplies.
• Power-off the equipment that is being serviced before you remove a field
replaceable unit (FRU) or other component. Remember that dangerous
voltages could still be present in some areas even though power is off.
• Ground all test equipment and power tools.
• Lift objects properly; read the information in “Lifting Techniques” (see
below).
• Do not remove, cut, or relocate any floor tiles indiscriminately. Before you
manipulate floor tiles, be sure that you understand the customer’s
environment and receive the customer’s approval. Remember, each
situation is different.
• Enforce good housekeeping practices in the equipment area to help prevent
fire and accidents.
Note: Important things to investigate and to be aware of include the use of
Halon® gas, under-the-floor smoke detectors, and cables to other
equipment installed nearby.
