Protecting Against Electrostatic Discharge - Dell PowerVault 130T User Manual

•
Place your feet 31–46 centimeters (12–18 inches) apart—approximately shoulder
width—and place one foot a little behind the other. Keep your back straight, because
even light loads can significantly increase pressure on the spine when you lean
forward.
•
Whenever possible use two hands and grip the load with your whole hand.
•
Keep the objects being lifted, lowered, or carried close to your body. The farther away
you hold an object, the more force it puts on your lower back.
•
Lift with your legs instead of your back. Leg muscles are some of the strongest. When
you squat and lift with your legs, you can lift more weight safely.
•
Alternate lifting with tasks less stressful to the same muscles. This gives muscles
time to recover.
Using Shoulders, Elbows, Wrists, and Hands
Follow these guidelines to minimize the possibility of injuring your shoulders, elbows,
wrists, and hands:
•
Work within your safety zone—the area between shoulder level and knuckle level of
your lowered hands.
•
Keep elbows bent to keep loads close to your body and decrease the amount of force
necessary to do the job, putting less weight and pressure on your shoulders.
•
Keep your wrists straight and avoid bending, extending, or twisting for long periods of
time.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside your computer. To prevent static
damage, discharge static electricity from your body before you touch any of your
computer's electronic components, such as the micro-processor. You can do so by
touching an unpainted metal surface on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal surface
to remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic discharge
(ESD):
•
When unpacking a static-sensitive component from its shipping carton, do not remove
the component from the antistatic packing material until you are ready to install the
component in your computer. Just before unwrapping the antistatic packaging, be
sure to discharge static electricity from your body.
•
When transporting a sensitive component, first place it in an antistatic container or
packaging.
•
Handle all sensitive components in a static-safe area. If possible, use antistatic floor
pads and workbench pads.
