• 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.
