FC § 5607.17
After the blast, the following procedures shall be observed: 1. Immediately after the blast has been fired, the firing line on electrically initiated shots shall be disconnected from the blasting machine. No person shall return to the blast area until allowed to do so by the blaster.
2.The blaster shall allow 20 minutes time for smoke and fumes to dissipate and for dust to settle before returning to or approaching the blast area.
3.The blaster shall inspect the entire blast area for misfires before allowing other personnel to return to the blast area. No mucking or drilling operations shall take place until all misfires are rendered safe in accordance with FC 5607.18. Once mucking commences, the blasting crew shall continuously check for undetonated cartridges, wrappers, caps and cap wires, which shall be removed from the muck pile prior to haulage to rock dumps, and handled in accordance with FC 5604.10.
4.In demolition blasting, the muck pile shall be wetted down and the blasting crew shall make a second search for undetonated explosives as set forth in FC 5607.17(3). The blasting contractor shall restore adjacent buildings and structures to their pre-existing condition by removing all dust, dirt and debris caused by blasting operations.
5.If blast impacts exceed the permissible limits in FC 5607.19.1, as determined by the blast monitoring specialist, blasting shall cease immediately and the blaster and/or other trained and knowledgeable representatives of the blasting contractor shall immediately investigate whether there is any damage to the affected buildings or structures.
