back. These risk factors are signifi cantly increased if
several of them are present at the same time.
The load should not be carried over excessive
distances (greater than 10 m). The frequency of
lifting, and the vertical and horizontal distances the
load needs to be carried (particularly if it has to be
lifted from the ground and/or placed on a high shelf)
can lead to fatigue and a greater risk of injury. If the
loads are handled whilst the individual is seated, the
legs are not used during lifting and stress is placed
on the arms and back.
There should not be excessive pulling, pushing or
sudden movements of the load. The state of fl oor
surfaces and the footwear of the individual should
ensure that slips and trips are avoided.
There should be suffi cient rest or recovery periods
and/or the changing of tasks particularly in the hot
ambient temperatures of the glassworks. This
enables the body to recover more easily from
strenuous activity.
The imposition of a high rate of work is a particu-
lar problem with some automated production lines
and can be addressed by spells on other work away
from the line.
The handling capability of an individual is approxi-
mately halved when he or she becomes a member
of a team. Visibility, obstructions and the roughness
of the ground must all be considered when team
handling takes place.
The
load must also be carefully considered during
the assessment – it may be too heavy. The max-
imum load that an individual can lift will depend on
the capability of the individual and the position of
the load relative to the body. There is therefore no
safe load but guidance is available from HSE litera-
ture, which does give some advice on loading
levels. If the load is too bulky or unwieldy, its
handling is likely to pose a risk of injury. Visibility
around the load is important, as is awareness that it
may hit obstructions or become unstable in windy
conditions. The position of the centre of gravity is
important for stable lifting – it should be as close to
the body as possible; however, this may be diffi cult
if the load is hot, such as in boxes or trays of
recently blown glass. They should be allowed to
cool suffi ciently.
The load becomes diffi cult to grasp when it is
carried over slippery surfaces, has rounded
corners or there is a lack of foot room. Sometimes
the contents of the load are likely to shift. This is a
