Received 26 October 2015; received in revised form 14 December 2015; accepted 15 December 2015ABSTRACTThe purpose of this study is to estimate the energy expenditure of working in a clean room formanufacturing embedded needles by ergonomic programs. Embedding needle is one of medicaldevices and it should be manufactured in a clean room. 3D static strength prediction programwas used to analyze the slow movements during embedding needle manufacturing in a cleanroom. Also the energy expenditure prediction program was used to estimate energy expenditurerates for materials handling tasks to help assure worker safety and health in clean room. Theenergy expenditures of the tasks were calculated using prediction equations derived from empiri-cal data. The energy expenditure rate of 3.09 kcal/min in a clean room didn’t exceed the3.5 kcal/min action limit guideline for an average 8-hour day set by the National Institute forOccupational Safety and Health (NIOSH). Energy consumption was calculated on the sameworking conditions as EEPP program, using an average body weight of female 20 years old to59 years who would be the candidates of the real workers.Key Words:Clean room, Energy expenditure rate, Ergonomic programs, Embedded needles,Static strength
