WARNINGS AND INSTRUCTIONS All explosive materials are dangerous and must be carefully handled and used following approved safety procedures either by or under the direction of competent, trained, and experienced persons, and in accordance with applicable state and local laws, regulations and ordinances. If, after carefully reading this entire leaflet, you have any questions or doubts as to how to use any explosive product, do not use it before consulting your supervisor, or Austin Detonator. If your supervisor has any questions or doubts, he should consult Austin Detonator before use. READ AND HEED THESE WARNING AND INSTRUCTIONS Storing and transporting electric detonators General • Always separate magazine from other magazines, buildings where persons might dwell, highways, and passenger railways. Be sure magazines are securely locked, and protected from weather, fire and theft. Keep the inside of the magazine clean, dry, cool and well ventilated. Always follow state and local laws and regulations concerning transportation. Use care when loading and unloading detonators. When transporting the detonators using motor vehicles, transport the detonators in their original packing. Transport only the required amount of explosives and detonators to the blast area. Always rotate stocks of explosive material so the oldest material in the magazine is used first. Keep explosives and detonators separate until the last possible moment. Never allow lighters, matches, open flame or other sources of ignition within 15 meters of the magazine. Don’t store detonators with other explosive material. Never exceed recommended storage quantity, time and temperature for detonators. Detonator must be stored in the environment with relative humidity not exceeding 80% and temperatures between -30°C and +40°C. Do not leave a vehicle containing detonators unattended. • • • • • • • • • • • • • Shipping classification Detonators are classified for shipment as Class 1, Division 4B and 4S, UN number 0255 and 0456. The classification is for railway, sea, road, and air transportation as per RID, ADR, ADN, IMDG-CODE and IATA-DGR. Marks and packaging Detonators are shipped in fibreboard cases, one box contains 5 or 10 inner boxes, depending on the size of case. Detonators are packed in inner boxes, each containing maximum of 100 Pcs (2 m leg wires length detonators). Quantity of detonators depends on the length of leg wires. Cases are marked with labels carrying the product identification, ID number and Class and Division Code. Shelf life and warranty Detonators shelf life is 24 months from the date of manufacture provided they are stored in the environment with temperatures between -30°C and +40°C. Warranty period is 24 months from the date of shipment. Handling electric detonators General • • • • Keep explosive materials away from children, unauthorized persons and livestock. Carry out the blasts under the supervision of a shotfirer. The shotfirer is responsible for firing the round. Don’t allow any lighters, matches, open flame or other sources of ignition in the blasting area. Always use permissible detonators (COALSTAR and/or TIMESTAR Cu shell execution) in flammable, gassy, or dusty environments, wherever required by applicable local laws and regulation. Never split the detonator open or use any other method to dissect and examine the inside of the detonator. • • Application and use of Electric Detonators ROCKSTAR, TIMESTAR, SEISMICSTAR detonators can be used in the following: • Open-pit mines. • Non-gassy, non-coal underground mines. • Gassy coal mines for coal and rock quarry (TIMESTAR Cu shell execution only). • Underground construction and lots not intended for use in underground coal mining (for example: tunnels, shafts, wells, underground containers, underground redevelopment construction, caves). ROCKSTAR, TIMESTAR, SEISMICSTAR detonators may not be used in the following: • Environments with explosive gasses, fumes, or dust where no concentration limit for the explosive gasses has been determined for blasting work. The fumes, gasses, or dust contained in a given environment are not considered explosive provided they do not reach the concentration needed for their initiation. • Materials in which use of detonators may cause fire or explosion.
COALSTAR detonators can be used in the following: • Open-pit mines. • Non-gassy mines. • Gassy coal mines for coal and rock quarry in the environments where concentration limit of methane or coal dust is determined by local regulation. • Underground construction and lots not intended for use in underground coal mining (for example: tunnels, shafts, wells, underground containers, underground redevelopment construction, caves). COALSTAR detonators may not be used in the following: • Materials in which use of detonators may cause fire or explosion. Preparing the Electric Blasting Circuit • For a given blasting work, always use detonators of a single electrical sensitivity produced by singe manufacturer. • Make sure that all leg wire ends are clean before connecting. • For the connections in the shotfiring circuit use connecting sleeves. • Keep the firing circuit completely insulated from ground or other conductors. • Hook up the round only after all unnecessary equipment has been removed. • For checking the circuit values use only instruments approved for use at the blast site. • The measured resistance of the firing circuit must correspond to the value calculated on the basis of the quantities and types of detonators used in a given blasting circuit. • Prior every use, test the shot firing cable for continuity and possible short circuit. • Regularly test blasting machine as well as the testing equipment for correct performance. • Attach detonator to detonating cord with tape or any other method recommended by manufacturer of the detonating cord. • Point the detonators in the direction of detonation. • Don’t attach the detonator for initiating the blast to the detonating cord until the blasting area has been cleared and secured for the blast. • Never attach exploder with shotfiring cable until you are ready to fire the blast. • Never make the final hook up to power source until all personnel are clear of the blast area. • Don’t bring or leave detonators near an open fire or hot stove. Initiation Detonators may be initiated only with approved blasting machine supplying energy of no less than: • 3 mJ/Ω (group I detonators, No fire current 0,18 A) • 16 mJ/Ω (group II detonators, No fire current 0,45 A) • 140 mJ/Ω (group III detonators, No fire current 1,2 A) • 2,5 J/Ω (group VI detonators, No fire current 4 A) COALSTAR detonator in methan or coal dust environment should be initiated with special blasting machine with the time limitation current max. 4 ms. Water resistance Detonators can be used in wet condition. Electric detonators ROCKSTAR, TIMESTAR and COALSTAR may not be exposed to water for more than 24 hours, the water pressure not exceeding 0.3 Mpa. Electric detonators SEISMICSTAR may not be exposed to water for more than 6 months, the water pressure not exceeding 1 Mpa. Temperature range Electric detonators ROCKSTAR, TIMESTAR and COALSTAR can be used in temperatures between -30°C and +60°C, Electric detonators SEISMICSTAR can be used in temperatures between -30°C and +80°C. Protecting against foreign sources of electricity • Never fire a blast above ground during a thunderstorm. • Always check for stray currents. • Never handle or use electric detonators: • when stray currents are present • during electrical storms • if static electricity is present • Never load boreholes in open-pit sites near electric power lines • Don’t use “I” and “II” electric detonators for blasting near H.T. lines and electric railways, near the RF sources. For this application always use “IV” detonators, if it is allowed by applicable local laws and regulation. Making of primers with detonators General • Assemble the primer carefully, regardless of the initiating method used. Primers should be assembled at the working place immediately prior loading. • Use a minimum of force for preparing the primers. Where necessary, holes should be pre-formed in the cartridge to allow easy insertion of the detonator. • Place the detonator in the center, with the base inserted in the explosive. Wherever possible, the complete length of the detonator should be inside the primer. • Do not subject the leg wires to an unnecessarily heavy pull; extensive force may break the leg wires or damage the insulation. Small diameter cartridges • punch a hole straight into one end of the cartridge • insert the detonator into the hole • tie leg wires around the cartridge using a half-hitch • never subject the leg wires to an unnecessarily heavy pull; extensive force may break the leg wires or damage the insulation. Large diameter cartridges • punch a slanting hole starting at the center of one end of the
