How many classes of registration are listed by the department?

• A. Four.
• B. Three.
• C. Five.
• D. Six.

Answer: (A)

Registration is grouped into four distinct classes to reflect different levels of training, oversight, and task scope in blasting operations. Four categories provide a clear path from entry-level registration to more advanced, supervisory credentials, ensuring that only qualified individuals perform higher‑risk duties and that safety requirements scale with responsibility. This four‑class structure matches the department’s published listings; having fewer would omit a needed level of oversight, while more would add unnecessary complexity without improving safety.
