Ergonomics Risk Factor(ERF) is a factor, which can cause trauma to the musculoskeletal system.
Ergonomics risk factor is the end product of disequilibrium of the W-WE ecosystem. This disequilibrium is normally caused by the component of work environment in the form of flaws in workstation and machine design, poor work procedure standard and non-conducive workplace environment. When this happen, the work environment will cause strain to the W-WE relationship, which will result in disequilibrium of the ecosystem.
This poor work environment condition and arrangement will produce strain in the form of ergonomics risk factors.
The magnitude of the risk factors will determine the course of the injury. If the magnitude of the risk factors above tolerance to human body, it will cause macro trauma in the form of sprain and strain.
On other side, if the magnitude of the risk is below tolerance, it only causes micro trauma, which can recover overtime. This process is called wear and tear of the musculoskeletal system. However, the micro trauma will accumulate and turn into major trauma if the risk is persistently imposed on the musculoskeletal system. The bottom line is ergonomics risk factors will cause MUSCULOSKELETAL DISORDERS (MSDs).
