|Dangerous parts of machinery
positioned so that they are not accessible to workers during normal
- Placement of machine's power apparatus against wall.
- Fencing off access to automatic machines.
- Feeding long stock into machine.
|Not always feasible,
particularly on non-automatic machines.
|Automatic Feeding and
||Operator not required to place his or her hands in the danger area.
- Self-feeder planers.
|Malfunctioning can create hazard. Controls should be set at a distance.
||Controls shrouded or recessed.
||Standard on many machines.
||Off switch should be easily accessible, and operator should be able to operate machine with ease.
||Hazardous part of machine automatically retracted after operation is complete.
||Counterweight/stroking mechanisms that return blade to rest after stock has been cut on over-head swing and radial saws.
|Improperly adjusted counterweights can create hazard. Blade may travel in wrong direction or may fail to retract.
|Placement of Controls
||Place controls sufficiently far from point of operation to prevent reaching into point of operation.
|Two hand controls sit at a distance from the point of operation.
|Stopping time of machine is a factor in calculating the distance.
