How often must the power output of an electric blasting machine be tested?

• A. Once each month
• B. Every week
• C. Daily
• D. Quarterly

Answer: (A)

The requirement to test the power output of an electric blasting machine once each month is rooted in safety and reliability standards within the mining and explosives industry. This frequency ensures that the blasting equipment remains in optimal working condition and capable of delivering the intended amount of power for effective detonation. Monthly testing allows for prompt identification of any potential issues that could affect performance or safety, ensuring that all safety protocols surrounding explosive materials are followed diligently.

This schedule balances the need for regular maintenance and oversight with practical operational considerations. More frequent testing, such as every week or daily, may not be necessary for typical operations and could impose unnecessary logistical burdens. Conversely, testing only quarterly could increase the risk of undetected malfunctions, leading to possible safety hazards during blasting operations. Thus, monthly testing aligns with industry best practices and regulatory guidelines, emphasizing both operational efficiency and safety adherence.
