Preventing Electrostatic Discharge Damage PowerVault 130T Service Manual 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. 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. 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. 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: 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. x 4473D
