| Production > Electrical Hazards |
 Electrical components within a woodworking facility poses many hazards.
To minimize the danger of these hazards, machines must always be grounded,
circuit breakers and fuse boxes must be
labeled, cords, cables, and plugs must be kept
in good repair, and outlets, switches, and fittings
must be covered. Any compromise in these or other safety precautions
could lead to serious injury, even death.

Potential Hazards:
-
Electrical hazards include electrocution, fire, or
explosions. Even slight shocks can lead to injury or
death.
Possible Solutions:
All electrical installations must comply with
OSHA electrical standards. Among the many
provisions included in the standards are the
following requirements:
- All of the metal framework on electrically
driven machines must be grounded, including
the motor, motor casing, legs, and frame. This
includes other equipment such as lights that may
be mounted on the machine. [1910.213(a)(11)]
|
- All circuit breakers and fuse boxes must be
labeled to indicate their purpose-that is, what
area of the plant they power or protect. Appropriately
rated fuses must be used. All unused
holes in electric boxes must be covered.[1910.303(f)]
- All electrical components must be approved by
a Nationally Recognized Testing Laboratory for
the specific location where the equipment will
be used.[1926.403(a)]
- All machines must have a main power
disconnect for lockout/tagout. [1926.304(a)]
|
|
These cords are improperly wired directly to the
electrical circuit, are not protected by a GFCI, and are
two-wire cords that are not grounded and not rated for
hard- or extra-hard service.
|
In addition, all machines should have the following:
- A magnetic switch or other device to prevent
automatic restarting of the machine after a
power failure. Such an unexpected start-up
could expose the worker to moving parts.
- An emergency stop device (panic bar or dead-man
switch) within reach of operators working
in the normal operating position.
- Clearly marked controls that are within easy
reach of the operator and away from the hazard area.
