General Hazard Sources

Mechanical Hazards
5.1.1
a) Lifting limits and Guidelines
The centre of gravity may be above the
lifting point. Support must be given to
prevent the valve assembly to rotate during removal. Do not
stand under suspended loads. Failure to do so can cause
serious personnel injury, damage to the valve and nearby
equipment.
Many precision parts have sharp corners which require
appropriate personal protective equipment during handling. Prior
to any attempt to lift an item, employees must first verify the
shipping marks for the weight.

Unstable, or non-ergonomic loads should always be
handled with the assistance of additional personnel or
appropriate mechanical means.
