ACTIVITY HAZARD ANALYSIS 01 DPT Activity: Direct-Push Analyzed By/Date: Reviewed By: Page 2 of 8 Principal Steps Potential Hazards Recommended Controls Drilling operations; set Uwork area and movi. Electrocutions, explosions, disastrous events, etc. Obtain and examine copies of all pertinent station drawings prior to performing the task. Locate and mark out the existing underground utilities. Obtain Underground Service Alert clearance prior to work. Inspect the area of drilling activity for overhead obstructions. Personnel will contact the service facilities engineer before working near utilities. Ensure that weight of rig is evenly distributed on ground and is not so heavy as to damage any underground lines that may be near the surface. rig into position. (cont.) Rig could contact overhead lines, including power lines, if it is transported with rig raised, causing electric shock. Vehicle may move if not properly set up Never move the rig when the mast is extended. Use spotter to properly position vehicle. Set brakes and place wheel chocks under front wheels of mobile rig. Extend stabilizer jacks, and ensure that footing is sound. Vehicle must be level to the vertical and horizontal planes. When raising rig, rig may not install properly due to the condition of rig and connecting cables. When raising rig, mast could come in contact with, or be in close proximity to, overhead power lines causing electrocution of workers. Inspect all components of rig to determine condition. Make all repairs before raising rig. The mast and other equipment must be at least 15 feet from any overhead utility lines. Verify the voltage of any overhead power lines. If any lines are above 50 kilovolt (kV), the clearance distance must be greater. Refer to Engineer Manual 385- 1-1, Section 11, Table 11-3 for clearance required for voltages above 50kV. When any part of the rig or equipment is in motion, worker will stand far enough away from the moving parts so that the worker is not pinned between the moving parts. Workers will not manually guide any moving part of the rig when it is raised up. Workers will not work under the rig or under the truck. If work must be done under the rig or truck, the drill crew supervisor will contact the Site Health and Safety Specialist to ascertain a safe method for lock-out of the equipment to ensure that adequate blocking is installed. Worker may become pinned between rig and other truck components, or worker could be pinned under truck rig if rig must be serviced from under the truck.
