If any changes need to be made to the blast specification, what should I do?

The Safety Health and Welfare at Work (Quarries) Regulations 2025 require the driller or shotfirer to inform the Explosives Supervisor of any changes to the blast specification. Any changes during the drilling operations and loading of shotholes that may affect the blast specification should be recorded and notified to the Explosives Supervisor and approval sought for any change. The changes should be formally approved before proceeding.
