A checklist for evaluating cab design of construction equipment.
Appl Occup Environ Hyg 2003 Oct; 18(10):721-723
Postural requirements of work should be considered in the design of work procedures and equipment in construction. The relationship between awkward posture and the development of fatigue and musculoskeletal disorders has been reported in laboratory and epidemiological studies. Despite the fact that operating heavy equipment has been found to result in a high prevalence of musculoskeletal symptoms and injuries, (10) there is a lack of quantitative data describing postural stresses among operators of construction equipment. This could be due to the time and complexity in collecting and analyzing postural data. The current study introduced a checklist for evaluating cab design and presented a case study using the checklist. The checklist is a general assessment tool. The checklist was useful in identifying characteristics that needed improvement. One limitation of a checklist is that it is, at best, an analytical tool. (11) It can assist in the process of identifying potential problems within a system, but for quantifying the problems, a comprehensive and systematic methodology is required for evaluating the work system. The checklist provides a static, instantaneous snapshot of characteristics during a specific time. Nevertheless, this and other checklists provide the critical point of departure in initiating the ergonomic analysis.
