Action to Take After an Electrical Accident
If an electrical accident results in an injury, take the following actions in this order:
1. Use caution. Be aware of potentially hazardous conditions that could cause further injury.
2. Disconnect power from the device.
3. If possible, send another person to get medical aid. Otherwise, assess the condition of the victim, then
call for help.
Prevention of Electrostatic Discharge Damage
Device components that are shipped in antistatic bags are sensitive to damage from static electricity. Some
components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging
static voltages whenever you handle plastic or foam packing material or if you move components across
plastic or carpets. Observe the following guidelines to minimize the potential for electrostatic discharge
(ESD) damage, which can cause intermittent or complete component failures:
