Example text

The cost of materials for ergonomic improvements (such as improved illumination) was $66,400. The labor cost for the implementation was about $120,000. The benefit/cost ratio for these improvements was approximately 40:1 for the first year—put another way, the payback time was about 1 week (Helander and Burri, 1994). Reductions in injury costs were fairly minor compared with the improvements in productivity and yield. This case study demonstrates that improvements in productivity can sometimes be extraordinary, and ergonomics can play a large role in productivity improvement.

They would inspect cards and components that were placed in the machine, and they inspected the finished product as it was removed from the machine. One of the most critical aspects of this task was to inspect the magazines containing the electronic components that were put into the card-stacking machines. A common problem was that the components were turned in the wrong direction in the magazines and would therefore be inserted in the wrong direction into the board. SPECIAL LIGHTING FOR INSPECTION The illumination was measured in the plant.

A guide to human factors and ergonomics 48 Under the cones’ sensitivity curve one can only see grey colors; below level 4 in the figure, there is only grey vision. This is because illumination of the rods will only cause a black and white perception. From this figure we may note again that the rods are more sensitive. There are several design implications that follow from the figure. 1. Cones do not operate in low illumination. To perceive small objects, such as small letters, the cones must be used.
