(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.
