The 'human' factor in construction equipment injuries.
Center for Excellence in Construction Safety Newsletter 1987 Dec; 1(3):6-7
Possible causes of worker injury in the construction industry and how human factor design improvement may have helped prevent them were discussed. Company injury forms rarely provide sufficient explanation of the causes of human failure, which result in worker injury. When patterns of injuries occur, poorly designed equipment may be the underlying cause. Several examples of such poorly designed equipment in the construction industry were cited. Heavy equipment operators have sustained foot, ankle, and leg injuries when dismounting due to inaccessible footsteps. Also noted was a lack of grab irons on construction equipment that allowed for safe three point contact climbing. Grab irons on the rear of some equipment assist mounting by using track cleats. However, when cleats are worn, feet may slip causing leg injuries. The large distance from the ground to the first track cleat has also been a cause of back injuries. Injuries resulting from mounting and dismounting account for 20 percent of lost time. The author suggests that notifying equipment manufacturers may reduce these human factor deficiencies and recommends that equipment be purchased with human factor designs in mind.
