• A. Yes, from the Chief Inspector of Explosives
• B. No, it is not necessary
• C. Yes, from any local authority
• D. Yes, from an environmental agency

Answer: (A)

Written approval is required from the Chief Inspector of Explosives for the mixing of ammonium nitrate and fuel oil to form an explosive because this process can create a highly sensitive and potentially dangerous explosive material known as ANFO (Ammonium Nitrate Fuel Oil). The Chief Inspector of Explosives is responsible for ensuring safety and compliance with regulations regarding explosives handling and usage. This approval process is critical to mitigate risks associated with the storage, handling, and operational procedures related to explosives.

The involvement of the Chief Inspector also reflects the stringent regulations governing explosive materials to prevent incidents that could harm personnel or property. Such approvals are typically part of a broader legal framework aimed at ensuring public safety and environmental protection when dealing with hazardous materials in mining and construction environments.
