SAFE BLASTING
Our stringent safety standards are emphasised throughout our
operations, no less in CMS Quarries Sdn Bhd where we make sure that
all blasting methods are performed in compliance with the correct
procedures. In 2018, we will use a remote camera mounted on a drone to
monitor the blasting condition.
There was an incident related to blasting in 2017 at Sebuyau Quarry. No
injuries were reported and only property damage was involved.
Blasting operations require at least six workers, they include the
Production & Maintenance Engineer, Quarry Supervisor, Chief Blaster,
Mining Supervisor and Drillers. Our blasting method is explained via the
following illustration:
A safety briefing
is delivered before blasting
to ensure it is carried out safely
The quarry supervisor or
another authorised person informs
all employees of the date
and time of the blasting
Blasting notices and red flags are
posted at the guard house at the
entrance of the quarry and
at the quarry pit to warn of blasting

The certified short-firer instructs
the explosive to be detonated
The quarry supervisor and other
authorised personal check that all
personnel are at least 100 metres
from the quarry face
Once the holes have been charged
with explosives, the blaster sounds
the siren six times
before blasting commences

Once the certified short-firer is
satisfied that all shots have been
fired, five minutes is given
to allow fumes to clear
One continuous long siren
indicates the completion
of the blasting
No workmen are allowed to
approach the quarry until the
‘all clear’ signal has been sounded
