What is the minimum specification for blasting cable?

The minimum specification for blasting cable is that it must be a #16-gauge insulated copper wire and at least 250 feet long. This specification is important for ensuring safety and efficacy in blasting operations. The use of #16-gauge wire provides sufficient conductivity, which is necessary for reliable transmission of electrical energy to the blasting device, while the insulation helps prevent accidental detonation and protects against environmental factors that could degrade the wire. The minimum length of 250 feet is specified to provide an adequate distance between the operator and the blast site, enhancing safety by allowing for a secure distance during the firing of the blast. Adhering to this standard helps to ensure that the blasting is executed safely and effectively, minimizing the risk of accidents in the mining environment.
