Which of the following is a valid registration category?

• A. Blaster.
• B. Supervisor.
• C. Operator.
• D. Manager.

Answer: (A)

Registration categories in blasting regulations identify the person who is authorized to perform blasting duties. The category that designates the individual who actually handles, places, and initiates the explosive charges is the Blaster. This role carries the regulatory responsibility for planning, charge design, timing, and firing, under safety rules and supervision. Because this credential directly authorizes the core activities of blasting work, it is the valid registration category. The other titles—Supervisor, Operator, Manager—are common job roles on a project, but they are not the formal registration category that authorizes blasting tasks themselves. They may oversee or manage operations, support the blast crew, or operate related equipment, but the certification or registration that grants legal authority to perform blasting duties rests with the Blaster.
