7 CCR 1101-9-6-7 - Electronic Initiation of Blasts

(A) Permittees shall be trained in the manufacturer's procedures for use of electronic detonators and shall follow the manufacturer's warnings and instructions, especially hook-up and safety precautions.

(B) Test equipment and blasting machines designed for use with electric detonators shall not be used with electronic detonators.

(C) Manufacturer's recommended practices shall be followed to protect electronic detonators from electromagnetic, radio frequency or other electrical interference sources.

(D) Electronic detonators shall only be fired with the equipment and procedures recommended by the manufacturer.

(E) Electric detonators and electronic detonators shall not be used in the same blast, even when made by the same manufacturer, unless the manufacturer approves such use.

(F) Test equipment and blasting machines that are designed for electronic detonators shall not be used with electric detonators.

(G) Electronic detonator wires, connectors, coupling devices, shock tube or other components shall be protected from mechanical abuse and damage.

(H) Electronic detonators of different types and/or versions shall not be used in the same blast, even if made by the same manufacturer, unless such use is approved by the manufacturer.

(I) Equipment or electronic detonators that appear to be damaged or poorly maintained shall not be used.

(J) Only blasting machines, testers, or instruments that are specifically designed for the electronic detonator system shall be used.

(K) Never mix or use electronic detonators and equipment made by different manufacturers.

(L) The handling or use of electronic detonators shall be discontinued during the approach and progress of an electrical storm. Personnel must be withdrawn from the blast area and moved to a safe location.

(M) Electronic detonator systems shall not be exposed to or used in operational temperature and pressure ranges outside those specified by the manufacturer.

(N) Electronic detonators shall never be tested or programmed in a booster, cartridge or other explosive component (primer assembly) before it has been deployed in the borehole or otherwise loaded for final use.

(O) An electronic detonator shall not be held while it is being tested or programmed.
