Which device is used to initiate detonation in blasting operations?

• A. Electric Blasting Cap
• B. Blasting Mat
• C. Tamping Pole
• D. Water Gel

Answer: (A)

In blasting, any detonation starts with an initiation device that translates an electrical signal into a reliable shock to ignite the main charge. The electric blasting cap serves this purpose. It contains a small detonator that, when energized by a blasting circuit, produces a quick and powerful impulse that drives the booster and then the main explosive. This setup allows for controlled, reliable initiation and can be used with timing devices or blasting machines to coordinate detonation as needed. Other items have different roles: a blasting mat is used to contain debris and reduce overpressure and fly-rock, a tamping pole is used to pack and position the charge in the borehole, and water gel is a type of blasting explosive material rather than an initiator.
