Recognition of risk factors is the first step in ergonomic hazard reduction. Are there areas with workers compensation claims, high turnover, or employee complaints? Target these first for assessment. The work process should be observed in as unobtrusive a manner as possible and for sufficient time to scrutinize all the processes.

 

When looking at operations from an ergonomic perspective one should consider the following questions.

 

Can the effective weight be lessened? This might be accomplished by ordering smaller bags, carrying one bag at a time instead of two, avoiding overloading carts, or any number of other means where the effort per individual task is reduced.

Can mechanical devices be used? Whenever possible use hand trucks, carts, or pallet jacks for moving materials to reduce employee effort. In the lab, use programmable or magnetic-assist ergonomic pipettes to greatly reduce the hand force required for these activities.

 

Is the equipment and facility in good repair? Is the equipment used appropriate? Wheels and casters on racks and carts should roll easily. The path of travel for wheels should be flat and without obstacles. Look for separations in grating that could snag wheels or abrupt doorsills that require significant effort to cross.

 

Is there better equipment available? For example in one facility review, we found a very heavy "home made" steel ramp was used to bridge the gap between truck and loading dock. A single worker "muscled" it into place. This plate was replaced by a pre-engineered light alloy ramp significantly reducing the weight. These all affect the force required to accomplish the day's work.

 

The State of Washington has excellent checklists for ergonomics hazard evaluation, and additional resources are available through OSHA.
