The objective of this study was to describe the frequently performed strenuous emergency medical service tasks that place firefighter/paramedics (FF/Ps) at risk for musculoskeletal injury and to hypothesize ways in which this risk can be reduced. The study group included 542 FF/Ps from 14 suburban fire departments. An initial list of tasks was identified through structured interviews with 29 FF/Ps. A list of the 11 most frequent and strenuous tasks identified in the interviews was validated through a mail survey returned by 374 FF/Ps. The five more frequently performed strenuous tasks identified were simulated, and the working postures and the forces applied by the workers were recorded and described. Each task was simulated and video data were used to determine gross postures and movement ranges. The biomechanical stresses were analyzed and the relative risk of low back disorder was quantified. The lower back disorder risk analysis identified the task components that contribute the most to the development of cumulative trauma back injuries. The strength limitation calculation indicated the task components during which musculoskeletal overexertion injuries were most likely to occur. The spine compression calculations indicated the task components during which disc related back injuries were most likely to occur. Several equipment modifications were suggested as being possible ways of reducing the risk of musculoskeletal injuries during frequently performed, strenuous tasks.
