Dust collection skip

Each day, up to 400kg of dust is produced from the back of the batch
heater drums. This dust was originally collected in plastic dust bins
which were then emptied through a hatch in the floor into a raised
loading shovel bucket. The dust bins were hard to move because of
their weight, and staff were exposed to potential inhalation of dust
when emptying them.
To improve safety, a metal chute was constructed to collect the dust
from the batch heater drums and feed it down pipes into a tipping
skip – fitted with braked castors so that it could be moved by hand. A lid was also manufactured to cover
the skip and contain all the dust.

Bitumen lines replacement
Johnston Roadstone > Leaton Quarry, Shropshire > 01952 777910
At Leaton Quarry, Johnston Roadstone replaced 20-year-old bitumen pipework on their Millar Coating
Plant. Three main health and safety benefits were accrued:
• previous leakage eliminated
• original secondary hot oil system replaced by thermostatically controlled electrical trace heating
• inspection and repair of all structural pipework supports.
Companies who are still using (or perhaps who have inherited sites using) secondary hot oil systems
should be aware of the potential fire and burn hazards. Reliability and maintenance schedules can also be
improved by the removal of the associated burner system and hot oil pump.

Bitumen spillage: capture and removal
Hanson Aggregates > Chipping Sodbury Quarry, near Bristol > 01454 314400
Hanson Aggregates’ Chipping Sodbury Quarry, near Bristol, has addressed the issue of containment and
mechanised removal of bitumen spillage.
All bitumen filler pipe flanges are brought together, above a removable grating. A steel lined concrete
catchment pit (slightly wider than the bucket of skid-steer loader) was constructed under the bitumen
delivery point. It has an angled bottom plate and vertical back plate to allow the skid-steer loader to dig
out the bitumen. The grate is easily lifted off and replaced manually. The pit is lined with dust or sand to
prevent sticking.

Splash guard for delivery flange
Aram Resources > Carnsew Quarry, Cornwall > 01326 375660
Following an incident at Carnsew Quarry where a bitumen delivery
driver caused a spillage, the safety team decided to design and
manufacture a splash guard to fit over the delivery flange.
Two different prototypes were built by John Hudson, in
consultation with Shell Bitumen’s delivery drivers. The preferred
design included a hinged cover secured with a safety bar to
allow the pipes to be easily connected. Once the pipes have been
connected, the cover is lowered into place and locked by the safety
bar. A “belt-and-braces” solution.
