1.2 Problem Statements.
Sawmill industry is among the manufacturing industry that applying a working environment which workers are requires to apply high forces, unsafe working posture,
manual handling operations, and repetitive motions in performing job task. Unsafe working posture such as bending, twisting, pushing, and lifting a heavy load are the
major contributors to the potential occupational injuries among an industrial workers. In sawmill industry, workers are highly expose to the occupational injuries due to the
job activities that require them to deal with the logs and processed timber. Manual handling device and a workstation design of workers to perform their job also
contribute to the occupational injuries. The design of workstation also can be a significant contributor to the workers to have a musculoskeletal disorder and other
occupational injuries. It is known that work-related musculoskeletal disorders are caused by multifactor operations of various risk factors. Safe working posture is
considered as vital contributor to feasible occupational health in most industries in Malaysia. Through feasible occupational health, the productivity and quality of
industries can be increased. Among these, the association of these risk factors with pain symptoms and work-related musculoskeletal disorders has been reported in many
studies in all typical manufacturing settings Bernard, 1997. Following are problems which related to the MSD injuries among the sawmill industry
workers:
a The sawmill industry is known to have a high level of manual handling, with tasks often involving high loadsforces, awkward postures, and repetitive
movements; some of the key risk factors for MSDs Tappin D. et. al, 2003. b At least 6500 new claims occurred during the four year period of the review,
equating to approximately 3250 new injury claims for Log Sawmilling and Timber Resawing and Dressing. Awkward posture is among the injury cause
in sawmills and veneerplywood mills COHFE, 2001.
