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