NIOSH Health Hazard Evaluation Report: HETA-2007-0124-3060, Ergonomic Evaluation of Workers at a Piston and Cylinder Linear Manufacturing Plant, Lake City, Minnesota, April 2008

摘要

On January 30, 2007, NIOSH received an HHE request from the International Brotherhood of Boilermakers to evaluate potential ergonomic hazards among workers at the Federal-Mogul piston and cylinder liner plant in Lake City, Minnesota. The request was prompted by upcoming redesign of workstations and cells. On March 8-9, 2007, NIOSH investigators visited the plant in Lake City, Minnesota. On March 8, 2007, NIOSH investigators (ergonomic specialists and a physician) held an opening conference with management, union officials, and the on-site chiropractor who provides medical care to the employees. Ergonomic specialists toured the plant to observe specific piston machining, cylinder liner machining, and foundry tasks. The physician interviewed workers about their medical status in a confidential setting. On March 9, 2007, NIOSH investigators held a closing conference and provided preliminary recommendations. The ergonomics evaluation indicated that most workers were at risk for developing MSDs from awkward postures and repetitive motions. Additional risk factors in specific areas included vibration and heavy lifting. Of the 26 interviewed workers, 19 reported work-related musculoskeletal pain or discomfort in the previous year. The most common complaints were low back pain and shoulder pain. Recommendations for reducing the risk of injury are contained in this report, including installing adjustable lifts, tables, and lift assists; and allowing adequate space around pallets.
