All vehicles hauling explosives will be properly loaded and display adequate explosives warning signs <br /> as specified by either OSHA,MSHA,DOT—whichever is applicable. <br /> 5.1. All vehicles will have appropriate safety equipment. Safety Triangles,Fire Extenguisher,and <br /> Explosive Placards are required by state and federal regulations. <br /> 5.2. Passengers shall not accompany explosives. <br /> 5.3. Equipment or other materials must never share the same cargo space with explosives. <br /> 5.4. Explosive vehicles, safety equipment, and day boxes shall be regularly inspected,maintained <br /> and cleaned. <br /> 5.5. All explosives, and any traces of explosives, must be removed from transportation equipment <br /> before it is serviced. <br /> 5.6. Explosives day boxes shall be properly built and marked as required by OSHA regulations. <br /> 5.7. When detonators and explosives are transported in a day box, they shall be separated by a <br /> four-inch hardwood,or equivalent,partition. <br /> 5.8. Only vehicles that are used for transporting or loading explosives shall be allowed on the blast <br /> site. <br /> 5.9. Accurate shipping papers shall accompany explosives when they are delivered to and from the <br /> job site. <br /> 5.10. Explosive transportation must be undertaken under the supervision of a person who is familiar <br /> with the hazards involved, and the actions required in the event of fire or other abnormal <br /> occurrence. <br /> 6. BLAST DESIGN <br /> In many blast applications, it is often impossible to fully satisfy all of the design objectives. <br /> Therefore, some sort of trade-off analysis is needed to balance design sacrifices based on priority. In <br /> blast design work, there are usually two general types of goals: 1) safety goals and 2) operational <br /> goals. Whenever safety goals conflict with operational goals, the safety concerns shall have the <br /> highest priority. For instance,producing minus 12-inch rock might be an operational objective while <br /> controlling flyrock is a safety goal. Since the safety goals must have the highest priority,the blast plan <br /> might specify the use of conservative amount of stemming to control rock movement,thus sacrificing <br /> rock fragmentation in the collar area. The following guidelines shall be used to evaluate all blast <br /> design choices: <br /> General Blast Design Considerations: <br /> 6.1. Blast designs shall never compromise safety, and safety goals shall have the highest design <br /> priority. <br /> 6.2. While satisfying all primary design objectives,blast designs shall be as simple as possible. <br /> Page 3 <br />
