Blasting will be conducted during daylight hours between 9 a.m. and 6 p.m., at which time guards will be posted to limit access. Horn warning signals for blasting will be as follows:
Pre-blast warning: At least one minute but no more than two minutes prior to detonation a warning signal of three blasts, each lasting about five seconds, will be given.
Post blasts: After the blaster-in-charge has determined the blast area is safe, the blaster-in-charge will sound an "all clear" signal, consisting of one long blast, lasting approximately 10 seconds.
All horn warnings should be of sufficient power to be heard from a distance of 1,000 feet from the blast site.
Certain conditions may cause a blast to be conducted outside the scheduled hours, such as rain, lightning, and other atmospheric conditions, operator safety or public safety.
