Tool Selection Non-Powered Electric Air Powered Powder Actuated Gas Powered Safety Note: If you have to modify a tool to make it work, you probably don’t have the right one! Non-Powered Hand Tools Impact tools such as chisels, wedges, or drift pins are unsafe if they have mushroomed heads. Wrenches with sprung jaws should be taken out of service. Wooden handled tools should be inspected periodically to make sure they are not splintered, cracked, or loose. Electric Tools Electric tools are difficult to guard completely They are subject to more abuse than stationary tools Cords must be inspected regularly These tools should be unplugged/battery removed for all maintenance procedures. Double Insulated Tools NFPA 70 permits double insulation for portable tools Third wire grounding is not necessary for double-insulated tools Double insulation works by isolating the tool’s internal electric components from the outer housing Circular Saw Safety Tips Set the blade’s depth to no more than 1/8” to ¼” greater than the thickness of the material Avoid binding the blade and causing a “kickback” Release the trigger if the saw binds or stalls Never pull the saw out of a cut until the blade stops Pneumatic Tools (Nail Guns) Make sure the nose guard safety spring is functioning properly Don’t hook up the power source until it is time to nail If the tool has to be carried while under power, stay away from the trigger and never carry against the body Safety glasses are a must! For Framers; Keep the off hand out of the way Never nail beyond your reach Keep the gun properly aligned with the work Be aware of surroundings and fellow workers Powder-Actuated Tools Only employees who have been trained and certified in the operation of the particular tool shall be allowed to operate Must be tested each day prior to use If it doesn’t pass inspection, it must be removed from service All required PPE must be worn Unfired caps should not be left in the gun or lying around The loaded tool should never be left unattended Gas Powered Tools Types include leaf blowers, trimmers, mowers, and chainsaws.
