Safety Recommendations
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded
power extension cables, and missing safety grounds.
• If an electrical accident occurs, proceed as follows:
— Use caution; do not become a victim yourself.
— Turn off power to the system.
— If possible, send another person to get medical aid. Otherwise, assess the condition
of the victim and then call for help.
— Determine if the person needs rescue breathing or external cardiac compressions;
then take appropriate action.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It
occurs when electronic components are improperly handled and can result in complete or
intermittent failures.
Always follow ESD-prevention procedures when removing and replacing components.
Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive
wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted
chassis frame surface to safely channel unwanted ESD voltages to ground. To properly
guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If
no wrist strap is available, ground yourself by touching the metal part of the chassis.
Caution For safety, periodically check the resistance value of the antistatic strap, which
should be within the range of 1 and 10 megohms (Mohms).
