Design and arrange for the authorization of the blast specification in accordance with approved procedures and practices.
This standard comprises the following:
1 Collate information for the blast design
2 Produce a detailed blast specification
3 Arrange for the authorization of the blast specifications
You will be required to demonstrate that you can determine design and arrange for the authorization of the blast specification in accordance with the relevant workplace procedures.
This activity is likely to be undertaken by someone whose work role involves Weapons, Ordnance, Munitions or Explosives work activities. This includes blasting personnel.
