Measures to prevent unauthorised use
Tarmac Northern, North Yorkshire > 01423 796800
Tarmac Northern has introduced a series of new working
practices to prevent both the unauthorised use of mobile
plant and to limit idle time.
To prevent unauthorised start up of mobile plant,
keypads have been fitted to the electronic computer
installed in the mobile plant. To start up the mobile plant
on
at the beginning of the day or after the engine has been
video
cut out, the ignition key has to be turned and also a
unique PIN code typed into the keypad. If an incorrect PIN
code is entered three times, an audible alarm will sound alerting others to the failed attempts.
To prevent mobile plant being left running whilst unattended, and limit idle time, a movement sensor
within the cab of the mobile plant detects occupancy. If the machine operative leaves the vehicle
unattended for a given time period whilst the engine is running, the sensor will automatically shut down
the engine. Another advantage of this method is the significant cost savings regarding fuel and engine
wear due to idle time on the engine when left running.
A secondary measure to ensure that the vehicle is not left running when unattended is attached to the
handbrake. If the handbrake is applied for a given time period, the same electronic computer – this time
linking the sensor on the handbrake with the stop solenoid on the engine – will shut down the engine.

Removal of keys from mobile plant
Aggregate Industries > High Roads Works, Lancashire > 07803 968112
Following a fatal incident where an unqualified individual
attempted to move a heavy vehicle, the team at this works
decided to implement a simple control system to prevent
operators leaving their keys in mobile plant.
The company purchased a batch of plastic covered key
chains which were then attached to the belt or loop of the
operators’ trousers, and fed through the pocket opening
of the overalls. At the end of the shift, the key chains are
removed and stored in the key safe.
Tarmac North West addressed this issue in a similar way. In addition, the company installed a secure key
box which was wall-mounted in the depot supervisor’s office.

On-board brake test meters
Tarmac Western > Cornelly Quarry, South Wales > 01656 746568
Cornelly Quarry, part of Tarmac Western, now specifies on-board brake testing equipment as standard for
new rubber-tyred plant. All mobile plant operatives have been trained in the brake testing regime. EPIC (or
equivalent) qualifications are required of mobile plant operators, be they employees or contractors. The
site enjoys the record of no mobile plant related accidents in the last ten years.
