POLICY It is the policy of the Forest Management Division that employees are properly trained and certified, and use explosives in conformance with state and federal laws. Blasting operations must be timed so as to minimize impact on the public. When hunters and anglers are expected to be using the forests in high numbers, such as during rifle deer season or the opening of trout season, minimize or eliminate the use of explosives. The safety and consideration of the public must be a top priority when conducting blasting operations." This policy permits only the use of Class "C" explosives. Transported quantities may absolutely not exceed 1,000 pounds. Only zero delay detonator caps may be used. No more than 100 zero delay blasting caps may be stored or transported. No more than 100 lbs. of detonating cord may be stored or transported. The Forest Supervisor will designate individuals to be certified as blasters for the Forest Management Division. All individuals designated by the Forest Supervisor to use explosives must be certified to handle and use explosives by completing a Forest Management Division approved explosives training course. All of Forest Management Division's use of explosives and training of blasters will be in conformance with this operational policy, the most recent edition of the National Fire Code NFPA No. 495, and the Michigan Department of Consumer and Industry Services, Construction Safety Standards, Part 27, "Blasting and Use of Explosives."

Handling and Use of Explosives The use of explosives for a specific land management project must be clearly described in writing and approved by the Forest Supervisor. The description of the project will include the type and quantity of explosives to be used. Number Page(s) POLICY AND PROCEDURES 124 6 of 8 Forest Title: Date Approved: Management EXPLOSIVES HANDLING Division February 1, 2000 One certified blaster will be in charge of the project and responsible for the whole operation. No more than two persons will be at the blasting site; a certified blaster and an assistant. The assistant must be a classified state employee. Specific instructions for the safe handling, mixing and use of binary explosives, as prepared by the manufacturer, shall be available to and strictly followed by all persons certified to use explosives by the Forest Supervisor. Two signs identifying the blasting area are to be placed on the roadway, in both directions, at a safe distance (1,000 feet) from the blasting site and must note that two-way radios are to be turned off. (See Michigan Department of Consumer and Industry Services, Part 27, R 408.42752.) All personnel, vehicles, and equipment are to be a safe distance from the explosion site. Blaster is to face blasting site to detect and avoid windblown debris. Wind direction is to be determined prior to blasting to avoid endangering others or other objects from wind/blast disbursed debris. All personnel involved must wear hardhats and eye protection. After the binary explosives have been mixed, according to manufacturer's instructions, it is a Class A explosive. Mix it at the site only. Use all of the mix. Do not transport mixed binary explosive. Blaster will keep blasting machine in his/her possession while wiring explosives. Always wrap detonating cord around explosives to insure detonation. Detonating caps will remain shunted until immediately before connection to the blasting machine. Before detonating, wire and detonating cap are connected; both are required to be checked for continuity before every detonation. Before detonation of charge, three loud yells will be sounded stating, "Fire In The Hole" using a powered loudspeaker (bullhorn). If there are conflicting procedures or information, the applicable federal and/or Michigan Department of Consumers and Industry Services Standards shall apply. 9. Misfires Do not go near an electrical misfire for thirty (30) minutes. Do not go near a non-electrical misfire for one (1) hour. Never try to dig out a misfire. Misfires cannot be left overnight. They must be dealt with immediately by blasting them in place with a second set of explosives. 10. Extraneous Currents; Radio Transmitters; Warning Signs A blaster shall take precautions to prevent the accidental discharge of an electric blasting cap from current induced by radar, a radio transmitter, an adjacent powerline, or other sources of extraneous electricity and shall comply with the standards set forth in the Institute of the Makers of Explosives, publication No. 20 (1978), entitled, "Radio Frequency Energy - A Potential Hazard in the Use of Electric Blasting Caps." Suspend all blasting operations during the approach of lightning, electrical, or dust storms. Baraga, Crystal Falls, Escanaba and Marquette Units must be especially cautious while blasting in the area of the U.S. Navy's Michigan ELF Transmitting Facility. Division personnel blasting in this area must have in their possession and be in compliance with the U.S. Navy publication, "Electric Blasting Guidelines in the Area Adjacent to the Navy's Michigan ELF Transmitting Facility", (revised February 1989).
