Can a factory splice on a reel of detonating cord be used in a blasting circuit?

• A. Yes, if secured tightly
• B. No, it must be replaced with a standard knot
• C. Yes, as long as it is inspected first
• D. No, but it can be used in non-blasting applications

Answer: (B)

A factory splice on a reel of detonating cord is not intended to be used in a blasting circuit, and the reason for this is rooted in safety and reliability. When detonating cord is factory spliced, it is designed to maintain certain performance specifications under controlled conditions. However, in the field, varying conditions and potential for security issues arise.

Replacing a factory splice with a standard knot is not simply a matter of personal preference or convenience; it ensures that there is a reliable and tested method of connecting the detonating cord. Standard knots or connections are often subjected to established safety standards and can be inspected for integrity, whereas factory splices may not provide the same assurance when utilized in a blasting operation.

This approach helps to ensure that the integrity of the blasting circuit remains intact and reduces the risk of unintended detonation or malfunction during volatile operations. Overall, following established protocols regarding the use of detonating cord is critical for maintaining safety standards in mining and blasting operations.
