the mat. The physical connection of the wrist strap and bonding wire between your skin, the ESD mat, and the hardware is known as
bonding. Use only Field Service kits with a wrist strap, mat, and bonding wire. Never use wireless wrist straps. Always be aware that the
internal wires of a wrist strap are prone to damage from normal wear and tear, and must be checked regularly with a wrist strap tester
in order to avoid accidental ESD hardware damage. It is recommended to test the wrist strap and bonding wire at least once per week.
• ESD Wrist Strap Tester – The wires inside of an ESD strap are prone to damage over time. When using an unmonitored kit, it is a best
practice to regularly test the strap prior to each service call, and at a minimum, test once per week. A wrist strap tester is the best
method for doing this test. If you do not have your own wrist strap tester, check with your regional oce to nd out if they have one.
To perform the test, plug the wrist-strap's bonding-wire into the tester while it is strapped to your wrist and push the button to test. A
green LED is lit if the test is successful; a red LED is lit and an alarm sounds if the test fails.
• Insulator Elements – It is critical to keep ESD sensitive devices, such as plastic heat sink casings, away from internal parts that are
insulators and often highly charged.
• Working Environment – Before deploying the ESD Field Service kit, assess the situation at the customer location. For example,
deploying the kit for a server environment is dierent than for a desktop or portable environment. Servers are typically installed in a rack
within a data center; desktops or portables are typically placed on oce desks or cubicles. Always look for a large open at work area
that is free of clutter and large enough to deploy the ESD kit with additional space to accommodate the type of system that is being
repaired. The workspace should also be free of insulators that can cause an ESD event. On the work area, insulators such as Styrofoam
and other plastics should always be moved at least 12 inches or 30 centimeters away from sensitive parts before physically handling any
hardware components.
• ESD Packaging – All ESD-sensitive devices must be shipped and received in static-safe packaging. Metal, static-shielded bags are
preferred. However, you should always return the damaged part using the same ESD bag and packaging that the new part arrived in.
The ESD bag should be folded over and taped shut and all the same foam packing material should be used in the original box that the
new part arrived in. ESD-sensitive devices should be removed from packaging only at an ESD-protected work surface, and parts should
never be placed on top of the ESD bag because only the inside of the bag is shielded. Always place parts in your hand, on the ESD mat,
in the system, or inside an anti-static bag.
• Transporting Sensitive Components – When transporting ESD sensitive components such as replacement parts or parts to be
returned to Dell, it is critical to place these parts in anti-static bags for safe transport.
ESD protection summary
It is recommended that all eld service technicians use the traditional wired ESD grounding wrist strap and protective anti-static mat at all
times when servicing Dell products. In addition, it is critical that technicians keep sensitive parts separate from all insulator parts while
performing service and that they use anti-static bags for transporting sensitive components.

Transporting sensitive components
When transporting ESD sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in
anti-static bags for safe transport.
Lifting equipment
Adhere to the following guidelines when lifting heavy weight equipment:
CAUTION
: Do not lift greater than 50 pounds. Always obtain additional resources or use a mechanical lifting device.
1 Get a rm balanced footing. Keep your feet apart for a stable base, and point your toes out.
2 Tighten stomach muscles. Abdominal muscles support your spine when you lift, osetting the force of the load.
3 Lift with your legs, not your back.
4 Keep the load close. The closer it is to your spine, the less force it exerts on your back.
5 Keep your back upright, whether lifting or setting down the load. Do not add the weight of your body to the load. Avoid twisting your
body and back.
6 Follow the same techniques in reverse to set the load down.
