is stemmed. Primers shall be made up just prior to loading. The cap
must be properly embedded in the cartridge and the primer seated in
the charge without rough handling.
I. Firing. Blast may be fired electrically with either a power
circuit or blasting machine. Such power circuits or blasting machines
shall at all times be maintained in good operating condition.
J. Firing With Power Circuit. When firing with a power circuit,
ample capacity shall be provided to supply the theoretical current
requirements of the blast. The detonators shall be connected in straight
series, straight parallel or parallel series. When firing with hand-driven
blasting machines, detonators shall be connected in straight series
or parallel series. Detonators may be connected in straight parallel
only when an adequate power supply is available. In every instance
of electrical wiring, regardless of the source of power, the Fire
Marshal's instructions shall be observed.
K. Power Wires. The power wires and leading wires shall be
thoroughly insulated and kept from contact with any electrical conductor,
air lines or pools of water or oil.
L. Leg Wires. The leg wires of the detonators shall be kept
short-circuited until connected or to the leading wires. All bare
connection shall be either taped or blocked up in position so as to
prevent current leakage or entrance of stray currents. While making
connections in the blast area, the leading wires shall be kept short-circuited
at the power source end but not grounded and shall remain under the
control of the blasters. They shall then be strung from the blast
area toward the source of power to make final connections for firing
the blast. Before connecting the leading wires to the power circuit,
the blasters shall make certain by a blasting galvanometer that continuous
circuit exist in the wiring. If this test shows either a short circuit
or no circuit, the reshunted leading wires shall be recoiled to the
blast area before investigating for trouble. Positive steps shall
be taken to prevent lead wires from dislodging and making contact
with overhead high voltage electric power lines. Should accidental
contact be made, the blasters shall prevent any person from touching
the blasting device and shall clear the area of all persons immediately.
No person shall enter the area until the blasters have notified the
owner of the power lines and then later has eliminated the danger
of electrical shock.
M. Power Circuit Controlled By Switch. A power circuit used
for firing shall be controlled by a switch located at a safe distance
to be determined by the blasters. Such switch, when in actual use,
shall be firmly fastened in position, thoroughly insulated against
grounds and wholly enclosed in a tight box that shall be kept closed
and locked at all times except while firing. No person other than
the blasters shall have access to the switch. The switch shall be
provided with a short circuit in the off position and shall be so
arranged that the box enclosure can be locked only when the switch
is in the off position.
N. Blasting Circuit Broken. When firing by means of a power
circuit, the blasting circuit shall at all times be broken in at least
one (1) place by a gap of at least five (5) feet on the incoming side
of the switch, except during the firing operation.
O. Blasting Machine. When firing with a blasting machine, the
blasting machine shall be located at a safe distance to be determined
by the blasters.
P. Leading Wires Kept Short-Circuited. When firing by means
of a blasting machine, the leading wires shall be kept short-circuited
until the shot is ready for firing. It shall not be connected to the
blasting machine until immediately before the time of firing and shall
be disconnected from the blasting machine and short-circuited immediately
after firing.
Q. Testing. Electric detonators and blasting circuits shall
be tested only by means of a blasting galvanometer designed for this
purpose.
R. Danger Zone. 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 no closer to the explosion than the blaster
himself) shall be effectively guarded to exclude all unauthorized
personnel. When practical, the blasters 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 blasters
to make certain that all persons have retired from there to a place
of safety. No blast shall be fired while any person is in the danger
zone.
S. Three Hundred Fifty Feet To Roadway. When the point of explosion
is within three hundred fifty (350) feet of a roadway, the blasters
shall, just prior to the blast, designate a sufficient number of employees
of the operation, 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 or at a distance
required by the Fire Marshal, whichever is greater, until the blast
has been fired.

fires but does not bring down the burden, it is permissible to reload
the bore hole if in suitable conditions, but only after the temperature
of the hole has been reduced by water or otherwise to not more than
one hundred fifty degrees Fahrenheit (150°F).
AA. Stemming. Each blast hole shall be stemmed to the collar
or to a point high enough to provide efficient confinement of the
charge and to minimize the chance of injury to persons from flying
material. Block holes shall contain at least eighty-five percent (85%)
of stemming material. For toe holes, the collar stemming shall in
no case be less than one-third (⅓) the depth of the hole.
AB. Transporting With Radio Transmitters. When electric blasting
caps are transported in a motor vehicle equipped with a radio transmitter,
they shall either be in their original package or stored in a closed
metal box that is lined with a cushioning material such as wood or
sponge rubber. When the electric caps are being placed into or removed
from the box, the transmitter shall not be used.

when in writing from the property owner and the Fire Marshal. A pre-blast
survey may not be required if the scaled distance is less than thirty
(30). "Scaled distance" means the actual distance
in feet divided by the square root of the maximum explosive weight
in pounds that is detonated per delay period for delay intervals of
eight (8) milliseconds or greater. If delay intervals less than eight
(8) milliseconds are employed or if instantaneous blasting is employed,
scaled distance shall be computed by dividing the actual distance
in feet by the square root of the total explosive weight in pounds.
BQ. Quarry Operations. When ground motion characteristics for
any given quarry operation have been determined by the Fire Marshal
based on instrumentation data submitted by the operator, the allowable
quantity distance relations between amount of explosives used in primary
blasting and distance from blast area shall be determined from the
accepted results of instrumentation at the given blast operation for
the various weights of explosives. The maximum amplitudes shall not
exceed those given in the table.
BR. Buffer. A buffer shall be maintained between quarry blasting
operations and all occupied uncontrolled structures by a distance
of one thousand two hundred (1,200) feet with a minimum distance of
four hundred (400) feet to any other property line, except property
lines owned by the owners of the quarry.
