Explain the difference between detonating cords and safety fuses.

Detonating cords are designed for specific applications where precise timing and reliability in detonation are critical. They consist of a flexible cord containing a core of high explosive material and are engineered to deliver a shock wave along their length at a consistent speed. This characteristic allows for synchronous detonations in multiple charges, which is particularly useful in complex demolition or military operations where timing can significantly impact the effectiveness and safety of the operation.

In contrast, safety fuses typically consist of a slower-burning material, often designed for igniting explosives at a longer delay. While safety fuses are reliable for certain applications, they do not provide the same level of precision as detonating cords, as they can vary in burn time based on environmental conditions and user handling.

The difference lies in the operational needs; detonating cords are preferred for scenarios demanding exact synchronization and instant initiation, making them ideal for sensitive and high-stakes detonations, as opposed to the broader and less controlled applications suited for safety fuses.
