Occupational Ergonomics
Budget: ₹1,000 – ₹1,500 INR
1) In a small manufacturing plant, the soldering iron shown here is used to solder connections on a large vertical panel. Several musculoskeletal injuries have been reported on this job over the last year in addition to many operator complaints. In general, it seems that:
a. It is difficult to see the point of application when using this tool.
b. The operators are gripping the tool unnecessarily tightly.
c. The power cord tends to get entangled.
d. Operators complain about wrist pain.
Redesign the soldering iron to eliminate the problems outlined above. Point out the ergonomic or other special features that have been incorporated into the design.
2) The worker shown below is driving 4 screws into a panel with a powered driver. His production quota is 2,300 panes per 8-hour shift. What specific ergonomic problems are found on this job? For each problem:
a. Specify an ergonomics improvement that would correct the problem.
b. Provide a specific work design principle to support these methods change.
