This article is a case presentation of an onsite ergonomic assessment of the risk factors for work-related musculoskeletal disorders (WMSDs) among three cooks working at a medium-sized Chinese restaurant in Hong Kong. The weight of workload was measured during the onsite assessment and the Ovako Working Posture Analysis System (OWAS), Rapid Upper Limb Assessment (RULA), and National Institute of Occupational Safety and Health (NIOSH) lifting equation used to assess the risk of WMSDs. The results showed that these cooks usually had to hold utensils for extended periods of time, toss woks, and barbecue meat, all of which demanded a lot of repetitive movements of the upper limbs. Future research is needed on the implementation of effective prevention measures, including administrative and ergonomic controls, to reduce the problems within this industry associated with such high-risk tasks.
