(O. No. 10039,1-9-81)
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:
Minimum Distance

5,000
50,000 — 100,000
7,000
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:

(26)
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)).
Lower frequency limits of measuring system, Hz
Maximum
(+ 3dB)
level in dB
0.1 Hz or lower — flat response

105 peak dBc
(B)
All measuring systems used shall have a flat frequency response of at least 200 Hz at the upper end.
(C)
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.

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.

*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.
