Each machine will have a positive electrical disconnect or isolation switch which can be locked out.
Electrically driven machines will be equipped with under voltage protective systems to preclude automatic restart after either a power failure or other under voltage condition.
Foot pedal mechanisms will be located and guarded so that they cannot be activated by falling objects or other accidental means. A pad with a non-slip contact area will be firmly attached to the pedal.
Controls will be available to the workers at their operating positions so that they do not reach over moving parts of the equipment. Control functions will be identified by printed words and color coding. Controls will not be wedged for continuous operation.
Power controls must have a way of locking out electrical power. Disconnecting or isolating switches will be mounted on a visible side of, or near, the machine and will be used to lock out power to the machine during repairs or adjustments. When the power is locked out, the isolating switch will be tagged.
The Machine Guard Program is designed to protect Employee(s) from hazards of moving machinery. All hazardous areas of a machine shall be guarded to prevent accidental "caught in" situations.

Many accidents are caused by machinery that is improperly guarded or not guarded at all. Important factor that must be kept in mind relative to machinery guarding is that no mechanical motion that threatens a worker’s safety should be left without a safeguard.
The following areas of machinery will be provided with barriers and/or enclosures that will effectively prevent personnel from coming in contact with moving components:
a) Point of operation exposures such as blades, knives and cutting heads.
b) Power transmission exposures such as belts, pulleys, shaft, gears, etc.
c) Top, bottom and backside exposures, such as the underside of table saws and the
wheels on band saws.
d) When a point-of-operation guard cannot be used because of unusual shapes or cuts,
jigs or fixtures which will provide equal safety for the operator will be used.
