Ergonomics is broadly accepted as the science of fitting the man to the job by means of ensuring that tool and workstation design minimises the need for awkward body postures and the straining of muscles by lifting heavy objects.  Although the Occupational Health and Safety Act of 1993 do not directly refer to the need for ergonomic assessment except for its mention in the Construction Regulations, ergonomic assessments are beneficial in that they assist employers to implement controls that may reduce the number of onsite injuries and musculoskeletal disorders and thus reduce the amount of man hours lost.
