The skip that runs up an incline track to storage bins at this plant in St Neots caused concern
for Lafarge Aggregates. Some asphalt inevitably remained in the bottom of the skip and required manual
jack-hammering to remove. Access was difficult and the risk of slipping, or receiving burns was considered
too great. An onsite fitter designed the solution – a new skip with a sub-frame that stays in position on the
incline track and an inner skip that can be removed easily, using the crane jib attachment on the loading
shovel. Development is already in the pipeline – a second inner skip will allow the one with build-up to be
replaced with a clean one in a matter of minutes and thus minimise downtime.

Glensanda Quarry is situated on the Morvern Peninsular,
where there is no road access. As a result, employees,
contractors and visitors all have to travel to site by boat.
The company identified that its jetties contained
multiple trip hazards, particularly in the wet. The wooden
gangways were covered with wire mesh to assist footing,
but were still a concern when boarding and landing.
The company purchased fibreglass decking and gangway
installation was carried out in-house. In addition, the
original steps were replaced due to their potential hazards
and restrictions.
Lever tap for sand pump

After a blockage in a sand pump at this East Dereham Quarry posed a danger to the workforce,
a simple solution has been found. Although pumping stopped when the blockage built in the pipeline, the
impeller continued to turn, heating the water and producing steam. No outward signs were obvious, but
an operative who released the bung to check the pump could be scalded with hot water and steam.
A SHE sub-committee was formed to discuss solutions. It was decided that a nipple should be screwed
into the casing and a lever tap fitted to the nipple. Although care is still needed, the risk of scalding is now
significantly reduced, as the angle of the tap is such that it can be turned with the operator’s hand out the
way of the flow of water.

Lone working: emergency system
Lafarge Aggregates > Northampton Railhead > 01604 632896
Unless sales demand increases, only one man is required to operate
the Northampton railhead. Following concerns about the welfare
of the lone worker should an accident occur, he now wears a device
that not only detects whether he has become unconscious, by body
angle and movement, but can also be manually activated in a ‘panic
situation’.
The device then dials pre-determined emergency contact numbers
and sets off an audible alarm and flashing beacon on the site.
