How should the detonator be oriented when taped to detonating cord?

• A. The tip of the detonator should point toward the cord
• B. The base end should point in the direction of the shock wave path
• C. The detonator can be oriented in any direction
• D. It should be horizontal for safety

Answer: (B)

The correct orientation of the detonator is crucial for ensuring that the detonation wave travels effectively along the detonating cord. When the base end of the detonator is pointed in the direction of the shock wave path, it ensures that the maximum energy of the detonation is directed into the cord. This orientation facilitates a reliable and efficient transfer of energy from the detonator to the detonating cord, leading to a successful detonation sequence.

In this configuration, the detonator will effectively initiate the detonating cord’s explosive reaction, which is essential for the intended blasting outcome. Any deviations from this orientation could potentially result in inefficient detonation, delayed ignition, or even a complete failure to detonate, creating unsafe conditions.

Other orientations, such as pointing the tip towards the cord or having the detonator in a horizontal position, do not optimize the energy transfer. Similarly, suggesting that the detonator can be oriented in any direction disregards the fundamental principles of explosive safety and effectiveness. Therefore, orienting the base end towards the path of the shock wave is the recommended practice in blasting operations.
