Overview

This standard comprises the following:

1 Supervise the preparation for the blast
2 Supervise the firing of the blast
3 confirm the conclusion of the blast

This activity is likely to be undertaken by someone whose work role involves Weapons, Ordnance, Munitions or Explosives work activities. This includes blasting personnel.

Performance Criteria

1 Supervise the preparation for the blast

P1 blast specification(s) are authorized and approved according to approved procedures and practice
P2 changes to the blast specification are approved and authorized
P3 effective communication is established and maintained with relevant person(s)
P4 arrangements are made for the delivery and receipt of sufficient, suitable materials to meet the blast specification
P5 adequate security measures for on-site explosives are maintained and records complete
P6 explosives are issued to relevant person(s) in accordance to approved practices and procedures
P7 checks are carried out to ensure activities involving the use, transportation and storage of explosives or explosive substances are carried out by relevant person(s)
P8 arrangements are made to ensure environmental controls are set up and monitored to meet local requirements
P9 blast sites are identified and established according to approved procedures and practices
P10 potential risks are identified and appropriate action taken to eliminate or minimize
P11 requirements for safety and security of the blast operations are clearly identified and communicated to all relevant person(s)
P12 problems and conditions referred by others are dealt with appropriately
P13 problems and conditions outside the responsibility of the candidate are referred to relevant person(s)
P14 work is carried out to approved procedures and practices and in compliance with statutory requirements

2 Supervise the firing of the blast

P15 checks are established and conducted to confirm the blast site conforms to the blast specification
P16 limits of the danger zone are confirmed and approved according to approved procedures and practices
P17 tools and equipment are approved as safe and suitable to meet the blast specification
P18 arrangements are made to ensure the removal of surplus explosives and the disposal of packaging.
P19 position and form of the blast initiation site are confirmed and approved
according to site operational procedures
P20 procedures are implemented to confirm evacuation of the danger area, and that visitors and contractors are in designated areas
P21 authorization to the shotfirer to blast at an agreed time is given when operating and environmental conditions are confirmed as suitable, according to approved procedures and practices
P22 problems and conditions referred by others are dealt with appropriately
P23 problems and conditions outside the responsibility of the candidate are referred to relevant person(s)
P24 work is carried out to approved procedures and practices and in compliance with statutory requirements
