Safeguarding Principle |

Location/
Distance |
Dangerous parts of machinery
positioned so that they are not accessible to workers during normal
operation. |
- 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
Ejection Methods |
Operator not required to place his or her hands in the danger area.
|
- Self-feeder planers.
- Sanders.
- Lathes.
|
Malfunctioning can create hazard. Controls should be set at a distance.
|
| Prevent Accidental
Startup |
Controls shrouded or recessed. |
Standard on many machines. |
Off switch should be easily accessible, and operator should be able to operate machine with ease.
|
| Miscellaneous |
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. |
