Handrails around the screen deck platform
Lafarge Aggregates > Little Paxton, Cambridgeshire > 01480 474721
The handrails around the screen deck platform offered
no protection when working on top of the screen deck
itself when changing the meshes.
The foreman fitter designed several extra sections of
platform with removable rails at the ends to allow
protection from falling over the end of the deck. Access
when working on the drives and shaft assemblies was
improved by positioning the extra platforms opposite
the shaft housings. Maintenance activity was also
improved by creating more room to work.

Drill rig fall arrest
Foster Yeoman > Torr Works, Somerset > 01373 456724
The engineering department has developed a drill rig fall arrest device which is fitted to the
top of the mast and provides a safe means of access for staff climbing the rig.

An inertia reel block allows free movement up and down the mast, but locks immediately in the event of
a slip, thereby preventing a fall. The locating device ensures that the support point is always immediately
above the working position, which keeps the wire free from snagging on the mast.

Stairway improvement
Tarmac Southern > Hothfield Works, Kent > 01233 611611
A steep staircase with a narrow tread and short risers led to several incidents of stumbling at Hothfield
Works in Ashford. At first, a handrail along the length of the internal side of the stairway was fabricated
– but this alone did not solve the problem. After consultation with the company’s SHE department,
alternating offset fall restriction barriers were extended into the stairway to reduce the risk involved.

Access to belt press
Huntsmans Quarries > Bishops Cleave Quarry, Gloucestershire > 01451 850555
The silt at this sand and gravel plant is dealt with via a belt press. In order to
access the main working parts of the press, an operator had to climb a vertical
set of ladders many times per day. To improve safety, the company decided to
replace these with a wide set of stairs with non-slip treads.
In addition, the plant’s belt press requires the addition of two flocculants – one
in liquid form and the other in powder. The powder needs to be placed in a
hopper at shoulder height. This had previously been done using 25kg bags, but
after reviewing this practice with its supplier, the company changed to using
15kg bags at minimal cost difference.
