(2) Blasting operations shall be conducted in accordance with all applicable state and federal laws and regulations. (3) For purposes of this rule, "certified blaster" shall means a blaster who possesses a valid certificate obtained pursuant to rule 1501:13-9-10 of the Administrative Code and "blaster-in-charge" shall means, for each blast, the certified blaster responsible for the loading of the blastholes (including delay detonator connections), detonation of the blast, and completion of the blast record required under paragraph (E) of this rule. (4) Blasting operations shall be conducted only under the supervision of a certified blaster. Only a certified blaster, or a member of the blasting crew under the direct supervision of the certified blaster, may detonate a blast. Any certified blaster who is responsible for conducting blasting operations at a blasting site shall give direction and on-the-job training to persons who are not certified and who are assigned to the blasting crew or assist in the use of explosives at that site. (5) Certified blasters, and other persons responsible for blasting operations at a blasting site, shall review and know the permittee's blasting plan and site-specific blasting requirements. The permittee shall keep a copy of the current blasting plan and permit map at the permit site for use by employees, contract blasters, and any other persons responsible for blasting operations. (B) Blasting times. (1) Blasts may be detonated only between sunrise and sunset. The chief may further limit the time periods for blasting if necessary and reasonable in order to protect the public health and safety. (2) Blasts may be detonated at other times only in emergency situations where rain, lightning, other atmospheric conditions, or operator or public safety so requires. When a blast is detonated under any of those circumstances, the blaster-in-charge shall document the reason for the late or unscheduled blast in the blast record required under paragraph (E) of this rule. (C) Blasting signs, warnings, and access control. (1) All blasting signs required to be posted shall: be of uniform design throughout the operation, easily visible, and made of durable material.
