How is a pigtail detonating connector attached to the detonating cord?

• A. By tying it with a bow
• B. By a square knot or taping together with 4 overlaps
• C. By glue
• D. By using a metal clip

Answer: (B)

The correct method of attaching a pigtail detonating connector to the detonating cord is by using a square knot or taping together with four overlaps. This technique ensures a secure and reliable connection between the detonating cord and the pigtail, which is crucial for the safe and effective initiation of explosives.

Using a square knot allows for a stable, firm hold that minimizes the risk of the connection coming loose. Taping with four overlaps further reinforces this attachment method by providing additional friction and protection against environmental factors that could affect the integrity of the connection. This practice is standard because it adheres to safety protocols that prioritize both the reliability of the explosive system and the safety of personnel handling them.

Other methods, such as tying it with a bow or using glue, do not provide the necessary security or reliability required in explosive settings. A bow knot can easily come undone under pressure or movement, while glue may not withstand environmental conditions such as moisture or temperature variations. Using a metal clip, although it may seem secure, can introduce points of failure that are not acceptable in high-stakes environments like mining. Proper techniques involving knots and taping are well established in the field to ensure the utmost safety and efficiency.
