What is a bad practice when tying in surface primacord?

• A. Leaving a line open-ended
• B. Connecting lines at sharp angles
• C. Making loops in the cord
• D. Using additional length of primacord

Answer: (A)

Leaving a line open-ended is indeed a bad practice when tying in surface primacord because it poses a significant safety risk. An open-ended line can create a situation where the primacord is not properly anchored, leading to potential misfires or unintended detonations. Properly tying in primacord requires ensuring that the ends are securely connected or terminated to prevent any accidental initiation or unintended outcomes. This practice ensures that the primacord is contained and that energy is directed properly during detonation, enhancing both safety and effectiveness in its applications. In contrast, the other practices listed, while they may present challenges or issues, do not carry the same level of immediate and severe risk that leaving a line open-ended does. For instance, connecting lines at sharp angles or making loops in the cord can impact the performance and effectiveness of the primacord, but they do not inherently create the same dangers as an unanchored line. Similarly, using additional length of primacord might complicate setup but does not compromise safety in the same manner.
