Never assume that power has been disconnected from a circuit. Check it to
make sure that it has been disconnected.

If you have to work on equipment that has exposed electrical circuits, observe
the following precautions:
– Make sure that another person who is familiar with the power-off controls is
near you and is available to turn off the power if necessary.
– When you work with powered-on electrical equipment, use only one hand.
Keep the other hand in your pocket or behind your back to avoid creating a
complete circuit that could cause an electrical shock.
– When you use a tester, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on a suitable rubber mat to insulate you from grounds such as metal
floor strips and equipment frames.

Use extreme care when you measure high voltages.
v
To ensure proper grounding of components such as power supplies, pumps,
blowers, fans, and motor generators, do not service these components outside of
their normal operating locations.

If an electrical accident occurs, use caution, turn off the power, and send another
person to get medical aid.
