Safety Guidelines
–
If possible, send another person to get medical aid. Otherwise, determine the condition of the
victim, and then call for help.
–
Determine whether the person needs rescue breathing or external cardiac compressions; then
take appropriate action.
In addition, use the following guidelines when working with any equipment that is disconnected from a
power source, but still connected to telephone wiring or network cabling:
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for it.
• Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at
the network interface.
• When installing or modifying telephone lines, use caution.
