Tanker gasket failures

As a result of near misses caused by tanker gasket failures, a working party was assembled at this depot to
analyse bitumen handling.
One problem lay in the fact that intake points are located next to the main traffic route that customers
use to access the asphalt plant load-out facility. This was addressed by installing fixed barriers to enable
traffic to be diverted via an alternative route during the discharge process. This diversion route is detailed
on an information sheet issued to customers on arrival.
The close proximity of the emergency shower to the discharge
connection point was addressed by fixing a steel fender with
60-degree deflectors to either side of the discharge point to
catch any bitumen spills as a result of failed gaskets.
The intake points, previously obscured from view of the plant
operator, can now be monitored using a fixed camera.
Other developments include training for all personnel in
receiving bitumen and the issuing of procedures for safe
delivery of bitumen to all delivery drivers.

Alarm system for drench
showers
Bardon Aggregates > Hulands Asphalt Plant, County Durham >
01833 628320
>
A new alarm system activated by the drench showers at Bardon Aggregates
means that the workforce is aware of an accident immediately and help is
at hand for the injured person. The audio / visual alarms are situated in the
laboratory, the mixer cabin and in an elevated position above the bitumen tanks. Toolbox talks have been
carried out with all personnel to train them on procedures following a bitumen incident.
Bitumen delivery controls
Tarmac Central > Caldon Low Quarry, Staffordshire > 01538 308282
Tarmac Central’s team at Caldon Low Quarry near Stoke-on-Trent have evolved a comprehensive new
system for controlling bitumen storage and delivery. Key elements include:
• locked off delivery pipes with key only available from control cabin
• drip tray incorporates slide rails so that it can be moved and emptied by fork-lift rather than manually
• parking of delivery vehicles controlled to allow unobstructed access to emergency shower
• high-level audible and visual alarms with camera to allow plant operator to monitor driver during
discharge
• delivery procedures clearly posted at delivery site with fire extinguishers for emergency use.
