What role do detonators play in explosives?

Detonators play a crucial role in explosives by initiating the explosive reaction. They are specially designed devices that produce a small but powerful detonation or shock wave that triggers the main explosive charge. This initiation is critical, as the explosive material itself may not detonate under normal conditions and requires a specific mechanism, such as the energy provided by a detonator, to begin the reaction.

Detonators can be electric or non-electric and are specifically engineered to create the precise conditions necessary for an explosive to function safely and effectively. By ensuring that the explosive charge is activated at the correct moment, detonators help control the timing and sequence of detonations, which is vital for both safety and effectiveness in various applications, such as construction or demolition.

In contrast to the other options, detonators do not stabilize explosive materials, provide safety during transport, or enhance the explosive power of the charges. Instead, they serve the essential purpose of starting the explosive reaction, making them a foundational component of safe and effective explosive usage.
