3.3. Considerations Affecting Placement of Bench Machines
The location of the machine in relation to the operator's position is extremely important in terms of both safety
and maximum efficiency. Studies have repeatedly shown that operator fatigue will be reduced, and greater
efficiency achieved, if:
1. the bench is of appropriate height, preferably with sound-deadening rubber mounts;
2. the machine is properly located on the bench with ample work areas on both sides to facilitate work flow;
3. the operator uses a swivel chair with padded seat and back rest which are independently adjustable; and
4. the foot switch, on machines so equipped, is placed on a rubber mat to maintain its movability, while
preventing it from sliding unintentionally.
Figure 8 illustrates proper machine location and operator position and the following:
A. Bench
The bench to be used should be of sturdy construction, preferably with rubber mounts to minimize noise. A
height of 762 to 812.8 mm [30 to 32 in.] is the most suitable for operator comfort and convenience. This height
allows the operator to rest both feet on the floor, thereby providing for the shifting of weight and leg position.
B. Machine Location on Bench
The machine should be located near the front of the bench with the "target area" (tooling area where the
product is applied) not more than 152.4 to 203.2 mm [6 to 8 in.] from the front edge. This location will eliminate
unnecessary operator motion and help to avoid back strain and fatigue.
Orientation of the machine should be such that the "target area" is facing the front of the bench and is parallel
to the front edge (access to the back of the machine MUST also be provided).
