4 Mudd rotary drilling 1 The raised derrick can strike overhead utilities, tree limbs or other elevated items. Never move the rig with the derrick up. Ensure there is proper clearance to raise the derrick, and that you are far enough away from overhead power lines. See the Utility Location H&S policy and procedure for guidance. 2 This technology uses fluid, which collects with sediments in large basin. Fluid can splash out and cause slipping/mud hazard. Liquid mixture can splash into your eyes. Wear rubber boots if needed, and keep clear of muddy/wet area as much as practicable. If area becomes excessively muddy, consider mud spikes or covering the area with a material that improves traction. Wear safety glasses. 5 Hollow stem auger drilling 1 All hazards in step 3 apply. Additionally,The raised derrick can strike overhead utilities, tree limbs or other elevated items Never move the rig with the derrick up. Ensure there is proper clearance to raise the derrick, and that you are far enough away from overhead power lines. See the Utility Location H&S policy and procedure for guidance. 2 Hands or fingers can get caught and crushed if trying to clean by hand or with tools while the auger is still turning. Auger should always be stopped and clutch disengaged prior to cleaning. 6 Air Rotary Drilling 1 This drilling method works with high air pressure and can generate flying debris that can strike your body or get in your eyes. When the drill rig is being driven into media, it will produce flying debris. The flaps behind the drill rig should stay closed whenever possible to reduce the risk of flying debris. Safety glasses and hard hat should always be worn when the drill rig is operating. When penetrating asphalt, protect surrounding cars that may be present to avoid damage to pain or windshields. 2 The raise derrick can strike overhead utilities, tree limbs or other elevated items. Never move this rig with the derrick up. Ensure there is proper clearance to raise the derrick and that you are far enough away from overhead power lines. See the Utility clearance H&S Standard for guidance. 3 When drilling through bedrock prior to groundwater, dust can be produced from pulverization. Inhalation of dusts/powder can occur. Supplemental water should be used to manage dust and/or dust masks should be used if necessary. 7 Reverse rotary drilling 1 This method will use fresh water to pump out drill cuttings through the center of the casing. Water/sediment mixture is generated and could cause contact with impacted soils or groundwater. Ensure the pit construction can hold the amount of cuttings that are anticipated. Air monitoring should also be used of pit area. 2 Fire hydrants are often used for water source. Hydrants deliver water at high pressure. Pressurized water can cause flying parts/debris and excessive slipping hazards. Water usage from fire hydrants should be cleared with local municipalities prior to use. Only persons that know how to use the hydrant should be performing this task. Ensure all connections are tight, and hose line is not run over to cut by traffic. Any leaks from the hydrant should be reported immediately. 3 Settling pit construction can cause tripping hazard from excavated soils, and plastic sheeting can cause slipping. Cone off the area to keep the general public/visitors away from the settling pit. Ensure proper sloping of excavation. 4 The raised derrick can strike overhead utilities, tree limbs or other elevated items. Never move the rig with the derrick up. Ensure there is proper clearance to raise the derrick, and that you are far enough away from overhead power lines. See the Utility Location H&S policy and procedure for guidance.
