711.220 Blasting — Rules and Regulations. All blasting
operations within the County shall be conducted in strict accordance
with the following rules and regulations and it shall be unlawful
for any person to fail to observe and follow said rules and regulations
when blasting. In the event there is a violation of said rules and
regulations, the Director shall have the power and it shall be his
duty to revoke the blasting permit issued in connection with the operation,
revoke the license of the blaster in charge, all in accordance with
the terms of this Chapter, and in addition, the violator or violators
may be punished as otherwise provided by this Chapter for violations
thereof.
| ||
|
(1)
|
Blasting operations shall be carried on with the smallest possible
number of persons present.
| |
|
(2)
|
All drill holes shall be of sufficient size so that the cartridges
of explosives can be easily inserted to the bottom of the hole without
forcing or ramming.
| |
|
(3)
|
Explosives should not be removed from the original wrapper before
being loaded into bore holes except when irregularities of the hole
make it impossible to load whole cartridges with safety or in block-holing
where small charges are desirable. This rule shall not apply to free
running explosives.
| |
|
(4)
|
Excessive ramming should be avoided in loading or tamping explosives
in a bore hole and wooden tools only, with no exposed metal parts,
shall be used for this purpose. In tamping, only hardwood rods without
metal parts, other than non-ferrous metal ferrules for extending the
length thereof, shall be used.
| |
|
(5)
|
When loading free running or bulk explosives, a bronze, wooden
or heavy paper funnel should be used unless the explosives can be
poured directly from a container into the hole in such a manner as
to prevent scattering of loose explosives around the collar of the
hole.
| |
|
(6)
|
When priming with electric caps, said caps shall be tested with
a blasting galvanometer after being loaded but before the hole 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.
| |
|
(7)
|
When firing with a blasting machine, the blasting machine shall
be located at a safe distance to be determined by the blaster.
| |
|
(8)
|
When firing by means of a blasting machine, the leading wires
shall be kept short-circuited until the shot is ready for firing and
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.
| |
|
(9)
|
Electric detonators and blasting circuits shall be tested only
by means of a blasting galvanometer designed for this purpose.
| |
|
(10)
|
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 explosion than the blaster himself), shall
be effectively guarded to exclude all unauthorized personnel. When
practical, 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.
| |
|
(11)
|
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 and fifty (350)
feet of the point of explosion until the blast has been fired.
| |
|
(12)
|
No person shall return to the danger zone until permitted to
do so by the blaster as announced by audible or visual signal.
| |
|
(13)
|
Immediately following the blast the area shall be examined by
the blaster for evidence of misfired charges.
| |
|
(14)
|
All misfires shall be reported at once to the superintendent
or manager who shall then determine the safe and proper method of
disposal. The unexploded charge shall be detonated if such can be
accomplished without risk of injury to personnel or damage to property.
If repriming is necessary, any stemming present in the hole may be
removed by a jet of water. The jetting tool should be of nonsparking
metal, rubber or plastic. If electric blasting caps are used for in-the-hole
initiation, an air jet should not be used.
| |
|
(15)
|
Drilling in any hole that is known to contain or have contained
explosives is prohibited until complete neutralization is effected.
| |
|
(16)
|
A complete record shall be kept by the blaster showing all misfires
and method of disposal.
| |
|
(17)
|
In case a charge fires but does not bring down the burden, it
is permissible to reload the bore hole, if in suitable condition,
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.)
| |
|
(18)
|
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 personnel 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 the depth of the hole.
| |
|
(19)
|
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.
| |
|
(20)
|
Unless otherwise expressly authorized in writing by the Director,
all blasting operations shall be conducted at no less distance from
any fixed or mobile radio transmitter than indicated in the following
table:

When it can be demonstrated by means of approved tests that
electric blasting may be carried out at lesser distances from the
transmitter than required by the table shown, the Director may allow
a variation from the requirements of said table.
| |
|
When blasting operations are located near highways or other
public ways, signs shall be erected at least five hundred (500) feet
from the blast areas reading: "BLAST AREA-SHUT OFF ALL TWO-WAY RADIOS."
The letters of these signs shall be not less than four (4) inches
in height on a contrasting background.
| |
|
(21)
|
In no case shall drilling be conducted closer than twenty-five
(25) feet to a loaded hole or a hole that is being loaded.
|
|
(22)
|
Holes shall be checked prior to loading to determine depth and
condition. Holes may be checked with a dolly or tamping block or by
visual inspection with the aid of a mirror. After any explosives have
been loaded, all measuring shall be done with a cloth tape or non-ferrous
measuring device and lead plumb bob, or a wooden tamping pole or wooden
dolly free of exposed metal parts.
|
|
(23)
|
Under no circumstances shall the amount of explosives taken within three hundred (300) feet of a potential point of explosion exceed the amount estimated by the blaster as necessary for the blast. Such explosives shall be stacked in piles at least twenty-five (25) feet from the nearest holes being loaded and at such distances apart, as provided in Section 32, that any premature explosion will not be likely to propagate from one (1) pile to another.
|
|
(24)
|
The explosives containers, if any, shall be opened at the pile
and carried up to the hole, one (1) case or unit at a time for immediate
loading or placed at a loading station not less than six (6) feet
from the hole except that not more than one hundred (100) pounds of
explosives shall be allowed at the loading station at any one time.
All empty explosives containers (boxes, bags, crates, etc.) shall
be properly disposed of, daily, in a safe manner.
|
|
(25)
|
Explosives shall be distributed in such a manner that the distances
from storage piles to the allowable maximum quantity of one hundred
(100) pounds of explosives at the loading station or between such
one hundred pound-loading station piles shall not be less than the
quantities shown in the following quantity-distance table:

Drill holes shall not be sprung when they are less than one
hundred (100) feet from the nearest hole containing explosives. Holes
that have been sprung shall not be charged with explosives until the
maximum temperature in any portion of such holes has been reduced
to one hundred fifty degrees Fahrenheit (150° F.). Where possible,
water is to be used for cooling purposes.
| |
|
(27)
|
When loading a blast primed with detonating fuse, the detonator
or detonators required for firing the blast shall not be brought within
fifty (50) feet of the hole area nor attached to the detonating fuse
until all persons, except the blaster and his assistants, have been
cleared from the danger zone.
| |
|
(28)
|
In all blasting where the firing of any one (1) hole is likely
to break into or damage another hole in the vicinity or where the
firing of any hole may propagate the charge in a loaded hole in the
vicinity, all holes which have been loaded shall be included and fired
in the blast.
| |
|
(29)
|
Water standing in blast holes should be bailed out, if possible,
or the holes shall be loaded with an explosive of adequate water resistance.
| |
|
(30)
|
Blasting crews shall consist of the minimum number of experienced
men to do the work in an efficient manner and should be organized
carefully and each man assigned to definite tasks to avoid confusion.
| |
|
(31)
|
A blast shall be planned before the loading is started. The
planned charge for each hole shall be recorded prior to the blast.
| |
|
(32)
|
The condition of each hole to be loaded and the amount, height,
and position of the explosives charge or charges placed in the hole
shall be recorded on a loading chart prior to the blast.
| |
|
(33)
|
Members of loading crews engaged in loading blast holes should
be prohibited from wearing hobnail or steel-plated shoes to avoid
striking sparks on rocks.
| |
|
(34)
|
Large dynamite cartridges may be dropped in blast holes only
when the hole is free from obstructions to the depth at which the
cartridge is to rest.
| |
|
(35)
|
Large dynamite cartridges shall not be dropped in blast holes
containing excessive water until the charge is above the water level.
| |
|
(36)
|
Large dynamite cartridges that have been wedged in a blast hole
shall not be tamped with a dolly. After pouring water into the hole,
attempts to dislodge or pierce them shall be made with a spear-shaped
wooden tamping block or a small-diameter wooden pole.
| |
|
(37)
|
Rough or ragged holes and holes partly closed by an obstruction
that cannot be readily removed shall be loaded with cartridged dynamite
lowered with a rope, with free running powder or dynamite cut in small
pieces.
| |
|
(38)
|
When loading a long line of holes with more than one (1) loading
crew, the crews shall be separated by the greatest practical distance
which can be maintained as the loading operations progress and which
is consistent with efficient operation and supervision of the crews.
Every effort shall be made to keep the loading crews a minimum of
twenty-five (25) feet apart and to prevent the simultaneous loading
of adjacent holes.
| |
|
(39)
|
Excessively large amounts of explosives shall not be delivered
to the loading area at one (1) time. If deliveries of explosives are
made by truck, the quantity permitted at or near the loading operations
shall be limited to one (1) truck load. Other trucks loaded with explosives
shall wait or be unloaded in separate safe places away from the loading
operations.
| |
|
(40)
|
Explosives should be delivered first to the holes farthest from
the truck to avoid driving or walking among piles of explosives.
| |
|
(41)
|
Explosives in excess of immediate requirements when removed
from the main storage magazine and delivered in the vicinity of a
blasting operation, shall be stored in a Class II magazine.
| |
|
(42)
|
The required stemming or tamping material shall be placed by
each hole before the delivery of explosives to the holes is started.
Stemming material shall be screened or free from excessively coarse
pieces.
| |
|
(43)
|
Stemming shall be placed in each hole to avoid damage to the
detonating fuse or leg wires of electric detonators.
| |
|
(44)
|
A single hole or any number of holes in a row should not be
fired when adjacent to or near one (1) or more other holes which are
loaded and which are not intended to be fired.
| |
|
(45)
|
All detonating fuses shall be covered with adequate stemming
where physically possible to reduce noise.
| |
|
(46)
|
The detonating fuse shall extend from the hole a distance of
one (1) or two (2) feet more than sufficient to compensate for any
subsidence, should be drawn taut and made secure on the top where
it will not interfere with loading operations or come in contact with
explosives on the ground.
| |
|
(47)
|
The detonating fuse shall be checked each time before stemming
material is used to see that it has not been broken; if it has, it
shall be repaired before proceeding.
| |
|
(48)
|
When a detonating fuse is used, main or trunk line splices shall
be factory splices or tight square knots. No splices or knots shall
be used in the drill hole.
| |
|
(49)
|
All branch line connections and all connections in the main
line other than splices shall be tight and at right angles.
| |
|
(50)
|
The main or trunk line shall be laid out free of kinks or coils
and all connections shall be inspected before firing the blast.
| |
|
(51)
|
When connecting an electric blasting cap to detonating fuse,
a connector for the purpose shall be used in accordance with the Director's
instructions. The cap may also be securely taped to the detonating
fuse.
| |
|
(52)
|
Caps shall not be brought to the loading area nor attached to
the detonating fuse until all is in readiness to fire the blast.
| |
|
(53)
|
Plain detonating fuse may be used for trunk lines or in shallow
drill holes, but reinforced or wire protected types shall be used
in deep or ragged holes.
| |
|
(54)
|
Toe hole blasting is defined as the removing of ledges or high
bottoms that remain after a main or primary shot or blast using moderate
quantities of explosives loaded in small diameter holes. In toe hole
blasting, the charge of explosives shall be pushed to the end of the
hole with a wooden pole using care not to block the hole or suitable
free-running blasting agents may be blown into the hole with an approved
pneumatic loader.
| |
|
(55)
|
Secondary blasting is defined as the reduction of oversize material
by the use of explosives to facilitate shovel operations or to be
accompanied by the crusher. It shall include mud-capping and blockholing.
In secondary blasting, wherever practicable, oversize fragments shall
be reduced to shovel or crusher size by use of the drop-ball method,
except as otherwise directed by the Director.
| |
|
(56)
|
Charges of explosives shall be confined in all cases (drill
holes) by suitable, inert stemming material
| |
|
(57)
|
No person, except the blaster and any others directly engaged
in loading block holes, shall be permitted within the immediate area
while loading is being performed. Loading of any block hole shall
be completed in one (1) continuous operation including insertion of
the primer and the stemming.
| |
|
(58)
|
Blast matting (which may include earth) shall be required when
blast operations and/or geological conditions create fly rock that
could damage or injure persons or property, or at the decision of
the Director.
| |
|
(59)
|
In all blasting operations, except as hereinafter otherwise
provided, the maximum peak particle velocity of any one (1) of three
(3) mutually perpendicular components of the ground motion in the
vertical and horizontal directions shall not exceed two (2) inches
per second.
| |
|
(60)
|
Instrumentation shall be in good operating condition and be
properly calibrated with a current (within one (1) year of date of
use) calibration sticker affixed to each instrument. If an instrument(s)
is found to be not operating properly or out of calibration, blasting
operations shall be halted until the appropriate repairs or recalibration
are performed or a proper instrument(s) is provided. Seismograph operator
shall be trained in the use of that instrument(s).
| |
|
(61)
|
Seismographic instrumentation shall be required on any blast
site where the nearest uncontrolled structure or public utility is
located within a scaled distance of sixty-five (65) (as defined in
Rule 69) or at the request of the Director. An uncontrolled structure
is defined as any occupied building not owned or controlled by the
explosives user. The seismograph shall be placed at or near the closest
uncontrolled structure(s).
| |
|
(62)
|
Blasting operations without instrumentation will be considered
as being within the limits set forth in this Subsection if at a specified
location on at least five (5) blasts instrumentation has shown that
the maximum peak particle velocity at the specified location is fifty
percent (50%) or less of the limit set forth in this Subsection, and
with written permission from the Director, provided, that for all
future blasts the scaled distance is equal to or greater than the
scaled distance for the instrumental blast. However, if a scaled distance
less than thirty-five (35) is employed, a seismograph is required
regardless of the seismic readings of previous blasts. "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. When blasting operations are contemplated which
would result in ground vibrations that would have a particle velocity
of any one (1) of three (3) mutually perpendicular components in excess
of two (2) inches per second, blasting operations may proceed after
receiving written consent from the property owner or owners affected
and the Director.
| |
|
(63)
|
(A)
|
Airblast shall be controlled so that it does not exceed the
maximum limits specified below at any uncontrolled structure (as defined
in rule 68(A)).

The permittee may satisfy the provisions of this Section by
meeting any of the four (4) specifications in the chart in Rule 73
of this Section; provided however, the 0.1 Hz or lower-flat response
or C-weighted slow response can only be used if approved by the Director.
| ||
|
(64)
|
When blasting in the vicinity of uncontrolled structures (as
defined in Rule 59(A)) the explosives user will determine the structures
lying within a scaled distance of thirty-five (35).
| ||
|
The distance will be determined by the following:
| |||
|
D = 35 (W2)
| |||
|
Where D is the distance limit and W is the maximum charge weight
per 8 ms delay interval. The explosives user will make a good faith
effort to contact the owner of structures within the distance limit
and offer to have a pre-blast inspection performed on their structure
at no cost to the owner.

storage area than as provided in (2) below shall be added to the quantity
of blasting agents to calculate the total quantity involved for application
of the aforementioned Table.
| |
|
(2)
|
Minimum intra-plant separation (distances between mixing units
and the oxidizer) storage areas and blasting agent storage areas shall
be determined by competent persons and these distances shall be approved
by the Director.
| |
|
(O. No. 2703)
| ||
|
711.250 Buildings Used for Mixing of Blasting Agents —
Construction.
| |||
|
1.
|
Buildings used for the maximum of blasting agents shall conform
to the requirements of this Section unless otherwise specifically
approved by the Director.
| ||
|
(1)
|
Buildings should preferably be of noncombustible construction
or sheet metal on wood studs.
| ||
|
(2)
|
The layout of the mixing building shall be such as to provide
physical separation between the finished product storage and the mixing
and packaging operation.
| ||
|
(3)
|
Floors in storage areas and in the processing plant should be
of concrete. Isolated fuel storage shall be provided to avoid contact
between molten oxidizer and fuel in case of fire.
| ||
|
(4)
|
The building shall be well ventilated.
| ||
|
(5)
|
Heat shall be provided exclusively from a unit outside the building.
| ||
|
2.
|
The design of the mixer should minimize the possibility of frictional
heating, compaction, and especially, confinement. Open mixers are
preferable to enclosed mixers. Bearings and gears should be protected
against the accumulation of oxidizer dust. All surfaces should be
accessible for cleaning. Mixing and packaging equipment should be
constructed of materials compatible with the fuel-oxidizer composition.
Mobile equipment, such as ready-mix concrete trucks, shall not be
used for blending fuels with oxidizers while in transit on public
highways. The provisions of this Section shall be considered when
determining blasting agent composition. The sensitivity of the blasting
agent shall be determined by means of a No. 8 test blasting cap at
regular intervals and after every change in ingredients or composition,
or as may be requested by the Director.
| ||
|
3.
|
Oxidizers of small particle size, such as crushed prills or
fines, may be more sensitive and hazardous than the ordinary prills
and should be handled with greater care.
| ||
|
4.
|
No liquid fuel with higher volatility than that of No. 2 diesel
fuel (minimum flash point of one hundred forty-five degrees Fahrenheit
(145° F.), ASTM closed-up procedure) shall be used.
| ||
|
5.
|
Crude oil and crankcase oil should not be used because they
may contain light ends that offer increased vapor-explosion hazards
or gritty particles that tend to sensitize the resulting blasting
agent.
| ||
|
6.
|
If solid fuels are used, they shall be chosen so as to minimize
dust-explosion hazard.
| ||
|
7.
|
Metal dusts (aluminum powder, etc.), peroxides chlorates, or
perchloratesi shall not be used unless such operations are conducted
in a manner approved by the Director.
| ||
|
8.
|
Unusual compositions shall not be attempted except under the
supervision of competent personnel equipped to determine the overall
hazard of the resulting compositions.
| ||
|
9.
|
All electrical switches, controls, motors and lights, if allocated
in the mixing room, should conform to the requirements of Article
502, Class II, Division 2 of the Electrical Code of St. Louis County;
otherwise they should be located outside the mixing room. The frame
of the mixer and all other equipment that may be used shall be electrically
bonded and provided with a continuous path to the ground.
| ||
|
10.
|
Washdown facilities should be provided. An automatic water-deluge
system with adequate capacity is recommended to protect mixers and
the finished-explosives storage area in the plant. Floors shall be
constructed so as to eliminate open floor drains and piping into which
molten materials could flow and be confined in case of fire. The floors
and equipment of the mixing and packaging room shall be washed down
frequently to prevent accumulation of oxidizers or fuels and other
sensitizers. The entire mixing and packaging plant shall be washed
down periodically to prevent excessive accumulation of dust.
| ||
|
11.
|
Smoking or open flames shall not be permitted in or within fifty
(50) feet of any building or facility used for the mixing of blasting
agents.
| ||
|
12.
|
Empty oxidizer bags shall be disposed of daily in a safe manner.
| ||
|
13.
|
Not more than one (1) day's production of blasting agents
or the limit determined by the American Table of Distances (Appendix
A), whichever is less, shall be permitted in or near the mixing and
packaging plant or area. Larger quantities shall be stored in separate
warehouses or magazines.
| ||
|
(O. No. 2703)
| |||
|
711.270. Transportation of Blasting Agents.

*As revised and approved by the Institute of Markers of Explosives,
September 30, 1955.
|
|
** "Barricaded" means that a building containing explosives
is effectually screened from a magazine, building, railway, or highway,
either by a natural barricade, or by an artificial barricade of such
height that a straight line from the top of any sidewall of the building
containing explosives to the eave line of any magazine, or building,
or to a point twelve (12) feet above the center of a railway or highway,
will pass through such intervening natural or artificial barricade.
"Natural barricade" means natural features of the ground, such as
hills, or timber of sufficient density that the surrounding exposures
which require protection cannot be seen from the magazine when the
trees are bare of leaves. "Artificial barricade" means an artificial
mound or revetted wall of earth of a minimum thickness of three (3)
feet.
|
|
Note: When a building containing explosives is not barricaded,
the distances shown in the Table shall be doubled.
|
|
NOTES TO AMERICAN TABLE OF DISTANCES FOR STORAGE OF EXPLOSIVES
|
|
Note 1. "Barricaded" means that a building containing explosives
is effectually screened from a magazine, building, railway or highway,
either by a natural barricade or by an artificial barricade of such
height that a straight line from the top of any sidewall of the building
containing explosives to the eave line of any magazine or building
or to a point twelve (12) feet above the center of a railway or highway,
will pass through such intervening natural or artificial barricade.
|
|
Note 2. "Natural barricade" means natural features of the ground,
such as hills or timber of sufficient density that the surrounding
exposures which require protection cannot be seen from the magazine
when the trees are bare of leaves.
|
|
Note 3. "Artificial barricade" means an artificial mound or
revetted wall of earth of a minimum thickness of three (3) feet.
|
|
Note 4. When a building containing explosives is not barricaded,
the distances shown in the Table shall be doubled.
|
|
Note 5. When two (2) or more storage magazines are located on
the same property, each magazine must comply with the minimum distances
specified from inhabited buildings, railways and highways, and in
addition, they should be separated from each other by not less than
the distances shown for "Separation of Magazines", except that the
quantity of explosives contained in cap magazines shall govern in
regard to the spacing of said cap magazines from magazines containing
other explosives. If any two (2) or more magazines are separated from
each other by less than the specified "Separation of Magazines" distances,
then such two (2) or more magazines, as a group, must be considered
as one (1) magazine, and the total quantity of explosives stored in
such group must be treated as if stored in a single magazine located
on the site of any magazine of the group, and must comply with the
minimum distances specified from other magazines, inhabited buildings,
railways and highways.
|
|
Note 6. The permanent storage of more than 300,000 pounds of
commercial explosives in one (1) magazine or in a group of magazines
which is considered as one (1) magazine is not permitted except by
specific approval of the Director.
|
|
Note 7. This Table applies only to the manufacture and permanent
storage of commercial explosives. It is not applicable to transportation
of explosives or any handling or temporary storage necessary or incident
thereto. It is not intended to apply to bombs, projectiles, or other
heavily encased explosives. For storage in connection with transportation,
see Section 711.180.
|
|
Note 8. All types of blasting caps in strengths through No.
8 cap shall be rated at 1 1/2 pounds of explosives per 1,000
caps. For strength higher than No. 8 cap, consult the Director.
