ACTIVITY HAZARD ANALYSIS 01 DPT Page 1 of 8 <br />Activity: Direct-Push Drilling Analyzed By/Date: Reviewed By: <br />Principal Steps Potential Hazards Recommended Controls <br /> Survey site. Slips, trips, and falls from various <br />agents. <br />• Work areas will be visually inspected and pre-existing <br />slip, trip, and fall hazards will be marked, barricaded, <br />or eliminated as feasible. Work areas will be kept neat <br />and orderly. Proper illumination will be maintained in <br />work areas. <br />Failure to properly survey site could <br />cause exposure to electrical hazards <br />and ground hazards. <br />• Conduct survey properly to identify all overhead <br />electrical hazards, including electrical hazards in the <br />path of the equipment as it is being transported. <br />Ensure that ground has no hazards such as unstable <br />soil, unexploded ordnance, or underground utilities. <br />Ensure that the findings of the survey and controls for <br />all potential hazards become part of this hazard <br />analysis. <br /> Drilling operations; inspection of drill rig. Improper inspection of rig could cause <br />workers to be exposed to hazards <br />associated with operating mechanical <br />devices, <br />• Ensure that the rig and all associated equipment are <br />inspected by a competent person and that the rig is in <br />safe operating condition. Inspect equipment; including <br />brakes, tire pressure, cables, and hydraulic and <br />pneumatic hoses, before use and at start of each shift. <br />Tag and remove from service faulty or unsafe <br />equipment. Verify that emergency shutdown systems <br />(at least two) are clearly marked, and all site workers <br />know locations. Verify that shutdown systems work <br />properly when trip wires are pulled or pushed. <br />Operator's manual must be available and reviewed <br />prior to operation. <br /> Drilling operations; set up work area and move <br />rig into position. <br />Failure to review site layout plan could <br />cause exposure to potential hazards <br />such as electrocution, damaging of <br />underground utilities, or tipping rig over <br />in unstable soil conditions. <br />• Do not move drill rig into any work area until site layout <br />plan has been completed and route of travel to any <br />work site has been assessed for hazards (overhead <br />lines and stability of roads and ground). At the pre- <br />activity safety briefing, discuss site layout plan and <br />analysis of route of travel, along with AHAs. Use a <br />spotter for positioning as necessary. Set brake and <br />place wheel chocks under front wheels of mobile rig. <br />Extend stabilizer jacks and ensure footing is sound. <br />Vehicle must be level to vertical and horizontal planes. <br />Do not position wheels (loads) or rig over manholes, <br />vaults, valve boxes, etc. Do not place rig within 15 feet <br />of any overhead electrical lines.
