S. Army Corps of Engineers General Safety Requirements Manual 1.2.9 Dupont Blaster's Handbook 1.3 DEFINITIONS 1.3.1 Suitable Materials. Suitable materials shall comprise all excavated materials free from roots or other organic material, trash, ashes, debris, and frozen material. 1.3.2 Unsuitable Materials. Unsuitable materials shall comprise excavated materials containing roots, organic material, trash, ashes, debris, frozen material, and such other unsuitable materials as designated by the Contracting Officer's Representative (COR). 1.3.3 Moistening (Wetting) and/or Aerating. Moistening (wetting) and/or aerating shall include any scarifying and/or mixing required to bring the materials to a desired moisture content. 1-2 1.3.4 Roadway. Roadway is that area included between the outside lines of slopes, ditches, and appurtenant structures and other features necessary to properly drain and protect the roadway. 1.4 SITE PREPARATION 1.4.1 Clearing and Grubbing. Trees, stumps, subsurface roots larger than 1 1/2 inches in diameter, and matted roots existing within the area bounded by lines 5 feet outside of building or structure foundations and roadway, unless otherwise directed by the COR, shall be removed to a dept.. of 18 inches and disposed of. Unless further excavation is required, depressions made by clearing and grubbing shall be filled with suitable material and compacted to make the surface conform with the density of the original ground surfac- Large rocks and boulders shall be removed and disposed of, unless other% ie directed by the COR. 1.4.2 Removal of Existing Pavement. In areas where pavement is to be removed, the existing pavement shall be cut in straight lines using a concrete saw or other approved method. Cuts shall be vertical and at least 1/4 the depth of the surfacing. The surfacing and base course shall be removed at least 6 inches beyond the limits of excavation. In areas where straight. neat jointing Ls not a requirement as determined by the COR, the metnod of pavement removal shall be at the Constructor's option. 1.4.3 Disposal of Debris. Cleared material and debris shall be disposed of in an area and in a manner as directed by the COR. Burning will not be permitted. 1.5 EXISTING SERVICE LINES, UTILITIES, STRUCTURES, AND BUILDINGS. Existing service lines, utilities, structures, and buildings shown on the drawings shall be protected and safeguarded from damage during construction operations in a manner approved by the COR and in accordance with OSHA 1926. When existing utility lines, whether or not shown on the drawings are encountered or damaged. the Constructor shall notify the COR immediately so the necessary measures can be taken Lo prevent interruption of the service. Repair of utility lines, if required, witl be at the discretion of the COR and may be accomplished oy others. 1.6 BLASTING. Blasting will not be permitted without written approval of the COR. Only thoroughly experienced, competent drillers, powdermen, and blasters shall be assigned to the required blasting operations. In addition, blasters must be certified by the State of Nevada. The charges shall be 1-3 so proportioned and placed that they will not, when fired, loosen the material outside the excavation lines shown on the drawings or specified herein. Any blasting procedure which results in breaking the material outside the established excavation lines or elevations, or which may be considered dangerous to personnel or property, shall be discontinued immediately and necessary steps taken to correct the procedure. Explosives shall be kept on hand in sufficient quantity to prevent delay of the work and shall be stored aboveground in dry, well-ventilated, fireproof magazines constructed and maintained at the Constructor's expense. A daily record shall be kept, showing the amoune of explosives on hand, the quantities received and issued, and the area in which each issue is used in compliance with recommended codes and standards. Unused explosives shall be returned to the magazines in the event they cannot be used immediately. The locations of magazines must be acceptable to the COR and shall comply with the "American Table of Distances for Storage of Explosives" developed by the Institute of Makers of Explosives, AMC 385-100, Blaster's Handbook, and OSHA 1926. Detonators shall be stored in a separate magazine at a safe distance from other explosives and places of work as designated by the COR.
