Erogomic Analysis of Construction Tasks for Risk Factors for OverexertionInjuries

摘要

Overexertion injuries are the single largest classification of injury inconstruction, accouting for about 24% of all injuries. Overexertion injuries generally occur as a result of performing a given task as planned. While overexertion injuries are not intentional, the underlying causes of the injuries are built into the prescribed tools and work methods. If the causes can be identified, it should be possible to engineer them out of the work. The objectives of this project are to develop a catalog of construction tasks and to analyze each task as a whole and each step of each task for the presence of seven generic risk factors for overexertion injuries: repetitive exertions, static exertions, forceful exertions, localized mechanical stresses, posture stresses, low temperature, and vibration. Ratings for each risk factor have been made on a three point scale: 1 = insignificant, 2 = moderate, and 3 = high. Virtually every activity has at least one risk factor with a score of 3. Of the sixty-five activities, fifty-three has at least one constituent task with at least two risk factors with scores of 3.
