(a) Temporary storage. Explosives may be stored in an approved Type 2 or Type 3 magazine or day box for one (1) day's usage only during daytime blasting operations and must be removed from temporary storage at the end of the work day. If the blasting firm or blaster has requested the Commissioner or his or her authorized representative to approve blasting at night, then the Commissioner or his or her authorized representative shall also consider appropriate requests to approve the extended use of the temporary storage during the nighttime blasting operations. The magazine or day box must be attended by a blaster, limited blaster or handler who has access to and knowledge of the contents. A blaster, limited blaster or handler must also be actively and directly in contact with, or within the sight of, without the aid of telescopic optical equipment or electronic devices, the temporary storage to maintain sufficient control.

(b) If the Commissioner finds emergency circumstances exist, in order to protect the safety and wellbeing of the public and individuals connected to the blasting operation, the Commissioner may direct his or her authorized representative to barricade the storage containers, relocate the explosive materials, or restrict the quantity of explosive materials that are handled at any temporary storage location.

(c) The blaster, limited blaster, handler or blasting firm shall post the following warning sign on all normal access roads to unattended explosive storage magazines:

DANGER

CALL___________________

The sign shall be weather-resistant with a reflective surface and lettering at least two (2) inches or fifty (50) millimeters high.

(d) The blaster, limited blaster, handler or blasting firm shall provide reasonable precautionary measures such as posting of signs and guards and redirection of traffic in areas beyond the initial blast area in the blast zone.

(2) Destruction of Materials

(a) In the event that it becomes necessary to destroy any explosives that present an immediate risk to people or property, all handling of explosives shall cease and the manufacturer or the Commissioner or his or her authorized representative shall be contacted immediately for assistance in coordination with other law enforcement officials. The manufacturer's directions for destruction shall be followed without deviation unless otherwise directed by the Commissioner or his or her authorized representative.
