What is the primary function of a capped primer?

• A. A device used to measure explosive charge weight
• B. A package designed to transmit detonation to other explosives
• C. A type of circuit breaker for electric detonation
• D. A device for interrupting an electric circuit

Answer: (B)

The primary function of a capped primer is to serve as a package designed to transmit detonation to other explosives. This component is crucial in blasting operations as it effectively transfers the energy from an initiating explosive, such as a blasting cap, to the main charge. In practice, the capped primer consists of a small explosive charge encased in a protective covering, which enhances its stability and ensures reliable detonation. When detonated, it generates a shockwave that detonates adjacent explosives, making it an essential link in the chain of explosive devices employed in mining, construction, and demolition. Understanding this function is important, as it directly relates to safety and effectiveness in blasting operations—ensuring that the energy is transferred efficiently without premature detonation or failure to initiate the subsequent explosives.
