Observing for Ergonomics

OBSERVING for Ergonomics

Most ergonomics problems result because the worker is forced to physically adapt to the tools and environment in order to perform the job. Like other physical hazards, consider what the risk factors indicate about decisions and behaviors of those designing the jobs. Common risk factors include:

Forceful Exertions

• heavy lifting, pushing or pulling, gripping 

• tasks that require great strength 

• sharp and blunt edges pushing on soft tissues of the hand, arm, etc. 

Awkward Postures

• any time a joint moves out of the neutral posture 

• the more extreme the posture, the greater the risk of injury 

• any joint can be affected including: bending, twisting, reaching, stooping, extending, etc. 

Repetition

• doing the same motion over and over again 

• does not necessarily require a fast pace 

Lack of Rest

• no time to recover from fatigue 

• skips rest breaks or rush to beat a quota 

• high paced jobs
