Who has control over blasting operations on site?

• A. A licensed blaster on site is in complete control
• B. The site safety officer
• C. The project manager
• D. The crew

Answer: (A)

Blasting operations are controlled by the licensed blaster on site because this person is specifically trained and authorized to plan, supervise, and initiate blasts. They develop the blast design, determine charge sizes and placement, and set the initiation sequence. They must verify that all safety measures are in place, including warning signals, clearance of the blast area, and ensuring that everyone stays out of danger zones before detonation. If conditions aren’t safe, they have the authority to delay or stop the blast. This focused responsibility ensures blasting is carried out in accordance with the plan and regulations, with clear accountability. The site safety officer oversees overall safety on the job but does not control blasting operations. The project manager handles scheduling, budgeting, and coordination, not the technical decisions of blasting. The crew performs their tasks under direction, but they do not initiate or control blasting decisions.
