Employee using a tool to assemble something at a table

Some electrical contractors use prefabrication as a way to increase productivity, improve quality, reduce waste, and save time. There are also a number of ergonomic benefits to prefabrication, such as controlling work heights, supporting tool weights, and controlling environmental conditions.

While some ergonomics-related risk factors can be controlled through prefabrication, it may create other job-specific hazards including heavy manual lifting, repetitive movements, awkward or static postures and contact stress. Employees should be aware of the potential hazards that are unique to a prefabrication setting.
