Safety and compliance

How we keep every blast safe.

Licensed people, written designs and the same procedure on every site, whether it is a quarry bench or a tower pit beside a house.

Blast safety procedure

The same eight steps on every blast

  1. 01

    Site survey

    Rock, nearby structures, utilities and access are assessed by our engineer.

  2. 02

    Blast design

    A written design is prepared and checked against what must be protected.

  3. 03

    Approval

    The design is signed by our licensed shot-firer and the client before work begins.

  4. 04

    Notice

    Police and nearby residents are informed before the blast.

  5. 05

    Drilling and checking

    Holes are drilled, measured and logged against the design.

  6. 06

    Charging

    Explosives are issued, recorded and loaded by licensed staff only.

  7. 07

    Clearance and firing

    The zone is cleared, sentries posted, warnings sounded, then the shot-firer fires.

  8. 08

    Post-blast check

    The area is checked for misfires before the all-clear, and results are recorded.

Exclusion zones and warnings

Nobody inside the zone

An exclusion zone is set for every blast according to its written design and the site around it. Nobody enters the zone from clearance until the all-clear.

  • Cordon

    The zone is marked with tape and signs before charging starts.

  • Sentries

    Sentries guard every access point and stop traffic and people.

  • Warnings

    Audible warnings are given before firing and the all-clear is signalled after the check.

  • Blast mats

    Mats cover the blast where people, roads or buildings are close.

Community notice

Neighbours know before we blast

  1. 01

    Before work starts

    We meet the local police and, where needed, the Grama Niladhari, and explain the work.

  2. 02

    Notice to neighbours

    Nearby residents are told the blasting times and the warning signals in advance.

  3. 03

    On the day

    Roads and paths inside the zone are closed for the short firing period only.

  4. 04

    After the blast

    We check for any concerns, record them and respond.
