What should be ensured when connecting Nonel tubing?

• A. Connections should be loose for flexibility
• B. Connections should be air tight and clean
• C. Connections can be made without additional security
• D. Connections can be made using any material

Answer: (B)

When connecting Nonel tubing, it is essential to ensure that connections are air tight and clean. This is crucial because Nonel (Non-Electric) systems are used for detonating explosives, and any leaks or contamination in the connections can lead to misfiring or reduced reliability in detonation. An air-tight connection prevents the escape of gases that could compromise the detonation mechanism, while clean connections help avoid any obstruction or failure due to dirt or debris.

Maintaining the integrity of the connection is vital for the safety and effectiveness of the blasting operation. Properly secured and clean connections help ensure that the Nonel system functions as intended, minimizing the risk of accidents and ensuring that the explosive energy is directed appropriately during the detonation process.
