A. 
In all blasting operations, except as otherwise authorized in this Chapter, the maximum peak particle velocity shall not exceed one and one-half (1.5) inches per second at the location of any structure. Peak particle velocities shall be measured in three (3) mutually perpendicular directions.
B. 
The maximum peak particle velocity shall be the largest of any of these three (3) measurements, and shall not apply at the following locations:
1. 
At structures owned by the person conducting the blasting activity and not leased to another party; and
2. 
At structures owned by the person conducting the blasting activity and leased to another party, if a written waiver by the lessee is submitted to the City Engineer prior to blasting.
C. 
Flyrock, including blasting material traveling along the ground, shall not be cast from the permit area.
D. 
Access to an area possibly subject to flyrock from blasting shall be regulated to protect the public. Access to the area shall be controlled to prevent the presence of unauthorized personnel during blasting until an authorized representative of the person conducting the blasting activity has reasonably determined:
1. 
That no unusual circumstances, such as imminent slides or undetonated charges, exist; and
2. 
That access to and travel in or through the area can be safely resumed.
E. 
All blasting shall be conducted so as to prevent injury to persons and damage to public or private property outside the permit area.
F. 
Before firing any blast, all means of access to the danger zone (the extent of which shall be determined by the blaster, but in no case to be closer to the explosive than the blaster himself/herself, or three hundred (300) feet, whichever is more) shall be effectively guarded to exclude all unauthorized personnel. The blaster shall then sound a warning of sufficient intensity and duration to be distinctly audible to all persons within the danger zone and all such persons shall retire beyond the danger zone. The danger zone shall then be examined by the blaster to make certain that all persons have retired therefrom to a place of safety. No blast shall be fired while any person is in the danger zone.
G. 
When the point of explosion is within three hundred (300) feet of a roadway, the blaster shall, just prior to the blast, designate a sufficient number of employees of the operator, each carrying a red warning flag, to stop all vehicular and pedestrian traffic on each possible route of travel within three hundred fifty (350) feet of the point of explosion until the blast has been fired.
H. 
No person shall return to the danger zone until permitted to do so by the blaster as announced by audible or visual signal.
I. 
Immediately following the blast area shall be examined by the blaster for evidence of misfired charges.
J. 
A complete record shall be kept by the blaster showing the number of holes, the amount of explosive used per hole, amount of explosive used per delay, length of delay, all misfires and method of disposal of misfires.
