Preventing Electrostatic Discharge Damage

Using Shoulders, Elbows, Wrists, and Hands

Follow these guidelines to minimize the possibility of injuring your shoulders,
elbows, wrists, and hands.
Preventing Electrostatic Discharge Damage
Anyone handling ESD-sensitive components must be aware of the damage ESD
can cause to those components and take proper precautions to prevent it. Handle
ESD-sensitive components only if you are protected against ESD. To meet this
requirement, always use an ESD grounding kit.

Precautions

Always take these general precautions when working with ESD-sensitive
components:
x
Place your feet 31–46 centimeters (12–18 inches) apart 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.
Do not use a pinch grip to lift large or heavy loads, because this puts a lot of
tension on hand and wrist tendons. Whenever possible, grip the load with your
whole hand, and use two hands.
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. When you squat and lift with your
legs, you can lift more weight safely.
Alternate lifting tasks with tasks less stressful to the same muscles. This
technique ensures recovery time.
Work within your safety zone—the area between shoulder level and knuckle
level of your lowered hands.
Bend elbows 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.
Use as much of your hands as possible when holding an object so you will not
have to pinch with your fingers. Alternate hands to give them rest.
Wear ESD protection whenever you install, maintain, or repair electronic
equipment.
Keep ESD-sensitive components in their ESD-protective packages until all
preventive steps have been taken and it is time 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.
