What is the correct position for the end of a blasting cap when connecting to a procore primer?

• A. Pointed in the opposite direction of the main charge
• B. Outside the primer
• C. Within the primer, pointed in the direction of the main charge
• D. At a right angle to the primer

Answer: (C)

The correct position for the end of a blasting cap when connecting to a procore primer is within the primer, pointed in the direction of the main charge. This arrangement ensures that the detonation wave from the blasting cap efficiently transmits through the primer and into the main explosive charge.

When the blasting cap is oriented this way, it maximizes the likelihood that the energy generated by the cap will effectively initiate the prime explosive material, resulting in a safe and reliable detonation sequence. Proper alignment is crucial for the efficiency of the blast, as it ensures that the explosive materials react as intended, minimizing the risk of misfires or incomplete detonations.

A blasting cap positioned incorrectly, such as outside the primer or in an ineffective angle, can lead to failures in detonating the primary charge or create hazardous situations during the blasting operation. Thus, positioning the blasting cap correctly is fundamental to ensuring operational safety and effectiveness in blasting activities.
