Bitumen emergency shower alarm
Ennstone Thistle > Daviot Asphalt Plant, Inverness > 01463 773100
Two new bitumen tanks have been installed at this asphalt plant with improved access for tanker
deliveries, including softened bends, reduced gradients and a clear, unobstructed area of hard standing.
The bitumen discharge procedure has also been improved with a new alarm system.
A red beacon and audible alarm connected to the emergency shower are situated on top of the bitumen
tanks to alert the operator and fully trained first aid representative of an incident.
In addition, Ennstone Thistle provided additional training on the correct methods to shut down the
bitumen supply safely, and installed a safety cabinet containing a helmet, neck foil, face shield and heat
resistant gloves to equip the first-aider with the mandatory personal protective equipment permitting him
to enter the bitumen delivery danger zone.

Modified flange for bitumen delivery
Midland Quarry Products > 01530 239451
After an incident where a tanker driver received serious burns when his
hose became detached from the pipe during a bitumen delivery, the
industry began recommending that a ‘Stokes Flange’ was fitted to each
fill-line. However, this in itself brought problems – bitumen pipelines and
fill-lines needed to be altered and this could often meant accessing highlevel
pipe joints.
Midland Quarry Product’s asphalt maintenance supervisor developed a
loose adapter flange, or ‘Fairbrother Adapter’ that has the benefits of
the ‘Stokes Flange’ in preventing the two hose flange bolts from moving
in the horizontal plane, but allows you to retain the original flange. It
is secured to the pipeline by chain so it is always available, and is easily
fitted by the bitumen delivery driver as he connects his hose to the tank
fill-line.
The concept of MQP’s adapter could also be applied to the tanker, where
it connects to the hose, and also to any other bulk-fluid tanker. The
safety, environmental and cost benefits that derive from the reduced
number of spillage incidents extend beyond the quarrying industry.

Bitumen emergency
procedure
Foster Yeoman > Botley Depot, Hampshire > 01489 784 509
An emergency procedure for bitumen burns has been implemented
at this Southampton depot. When a member of staff pulls the cord
to activate the emergency water shower, others are alerted by a
green flashing beacon above the shower and a beacon and alarm
in the mixer cabin. They can then initiate an emergency response
using the telephone numbers and use advice on treating bitumen
burns clearly displayed nearby.
