Must a blaster be present when a shot is fired?

• A. No
• B. Sometimes
• C. Yes
• D. Only if requested

Answer: (C)

A licensed blaster must be present to supervise and authorize every detonation. Blasters are trained to assess the blast area, confirm that all personnel are clear, verify warnings and barricades are in place, and ensure the proper timing, delay sequence, and initiation method are set. This oversight helps prevent accidents and ensures compliance with regulatory safety requirements. Because blasting is highly hazardous, no shot should be fired without the blaster on site to oversee the operation.
