Abstract
Floor Coverers have a high prevalence of knee related injuries. The objective of this study is to quantify whole body ergonomics exposure for Floor Coverers in the greater Boston area. A total of 6213 observations (about 100 hours) were made on 49 Floor Coverers by 7 trained observers in 8 construction sites. Awkward leg postures were common. “Kneeling/Crawling” was observed 61.2% of the time. Non-neutral trunk postures were observed frequently. “Severe Flexion” was observed 36.6% of the time, “Mild Flexion” 12.9%. “Manual Material Handling” was observed most frequently during “Hardwood Floor” (36.1%). Hand tools were used more frequently (32.6%) than power tools (5.2%). “Severe Trunk Flexion” did not always lead to heavy trunk load with kneeling postures. Leg postures should be considered before trunk postures were converted to trunk loads. Awkward leg postures are a big problem for Floor Coverers. A majority of the tasks happened near or on the ground.
