Health and Safety
Manual Handling Operations Regulations 1992 defines manual handling as: “any
transporting or supporting of a load (including the lifting, putting down, pushing,
pulling, carrying or moving thereof) by hand or bodily force”. The Regulations set no
specific requirements such as weight limits. However common sense still has to be
used based on an ergonomic approach for each individual.
