GENERAL
Equipment that supplies electrical power can cause serioueinjury or death,
or damage to other equipment or property. The operator must strictlv
observe all safety rules and take precautionary actions. Safe practices
have been developed from past experience in the use of power source equipment.
While certain practices below apply only to electrically-powered equipment,
other practices apply to engine-driven equipment, and some practices to both.
SHOCK PREVENTION
Bare conductors,
electrically-live or terminals in the output circuit, or ungrounded,
equipment can fatally shock a person. Have a certified
electrician verify that the equipment is adequately grounded and learn what
terminals and parts are electrically HOT. Avoid hot spots on machine. Use'
proper safety clothing, procedures, and test equipment.

Keep clothing dry, and never work alone.
1. Installation and Grounding of Electrically Powered Equipment
Equipment driven by electric motors (rather than by diesel or gasoline
engines) must be installed and maintained in accordance with the ?lational
Electrical Code, ANSI/XFPA 70, and other applicable codes. A power
disconnect switch or circuit breaker must be located at the equinment.
