• Always look carefully for possible hazards in your work area. Examples of

these hazards are moist floors, nongrounded power extension cables, power
surges, and missing safety grounds.

• Do not touch live electrical circuits with the reflective surface of a plastic

dental mirror. The surface is conductive; such touching can cause personal
injury and machine damage.

• Do not service the following parts with the power on when they are removed

from their normal operating places in a machine:
– Power supply units
– Pumps
– Blowers and fans
– Motor generators
and similar units. (This practice ensures correct grounding of the units.)

• If an electrical accident occurs:

– Caution: do not become a victim yourself.
– Switch off the power.
– Send the victim to get medical aid.
