| Work setting and tasks | Manufacture and assembly of jet aircraft. Use of air-driven, hand-held tools (drills, routers, sanders, rivet guns, screw guns). |
| Work-related musculoskeletal problems found | Limited to evaluation of tool properties. |
| Ergonomic risk factors found | Vibration levels in use of tools exceeded recommended exposure limits for typical work shift durations. |
| Recommendations | Continue effort to purchase new vibration reduced pneumatic tools. Maintain or replace tools producing high vibration levels due to wear and tear. Institute health care management practices ensuring early detection of hand/arm vibration disorders. Allow more rest breaks when using tools with highest vibration levels. |
