Electrostatic Discharge (ESD) Damage
• Be sure to keep your wrists straight. Avoid bending, extending, or
twisting your wrists for long periods of time.
• Do not use a pinch grip to lift large or heavy loads because the way you
lift also can affect the tendons in your hand. When you grasp an object
between your thumb and fingers, you put a lot of tension on hand and
wrist tendons. Use both hands–use one for a while, and then use the
other–to give them rest.

Electrostatic Discharge (ESD) Damage Prevention
Anyone who handles ESD-sensitive components must be aware of the damage
that ESD can cause to electronic components and must take the proper
precautions to prevent it. Also, anyone who performs maintenance on
StorageTek equipment must complete an ESD-basics course.
CAUTION:
Potential damage to equipment: Handle ESD-sensitive components only
under ESD-protected conditions. To meet this requirement, always use a
grounding kit and always follow these ESD precautions and procedures
when you are servicing equipment or handling ESD-sensitive
components.
ESD Precautions
Always take the following general precautions when you work with ESD-
sensitive components:
• Wear ESD protection whenever you install, remove, maintain, or repair
equipment.
• Keep ESD-sensitive printed-circuit components in their ESD-protective
packages until you have taken all ESD-preventive steps and you are ready
to install the component.
• Do not allow anyone to touch or handle an unprotected ESD-sensitive
component unless that person has taken all ESD precautions.
• Reinstall all equipment covers and close all equipment doors after you have
completed the work.
• If the grounding-kit work surface has been exposed to temperatures above
66ºC (150ºF) or below 4.5ºC (40ºF), acclimate the work surface to room
temperature before you unroll it.
• Immediately place any component that you have removed into an ESD-
protective package.
• Keep the grounding-kit work surface clean.
