What is the recommended exposure time for a Nonel detonator assembly in an explosive that uses fuel oil as a component?

• A. 3 days
• B. 6 days
• C. 10 days
• D. 15 days

Answer: (B)

The recommended exposure time of 6 days for a Nonel detonator assembly in an explosive that incorporates fuel oil is based on the factors influencing safety and performance in explosive operations. Specifically, this time frame allows for a balance between ensuring that the detonator does not degrade or become less effective while also minimizing the risk of unintended detonation due to environmental factors or mishandling.

The science behind explosive materials suggests that certain components, like fuel oil in an explosive mixture, can be sensitive to environmental conditions such as temperature and humidity. In this context, a 6-day exposure time is established to maximize functionality and reliability of the detonator assembly in real-world applications, while also adhering to safety guidelines that protect personnel and equipment.

Longer exposure times, such as those exceeding 6 days, could increase the likelihood of negative reactions with moisture or temperature fluctuations, leading to potential risks or failures during the actual detonation process. Therefore, sticking to the 6-day guideline is crucial for maintaining operational safety and performance standards in mining and explosive operations.
