General Safety Precautions- Electric Tools Employees using electric tools must be aware of several dangers; the most serious is the possibility of electrocution.
General Safety Precautions- Electric Tools Under certain conditions, even a small amount of current can result in fibrillation of the heart and eventual death.
General Safety Precautions- Electric Tools Electric tools must either have a three-wire cord with ground and be grounded, be double insulated, or be powered by a low-voltage isolation transformer. General Safety Precautions- Electric Tools These general practices should be followed when using electric tools: Electric tools should be operated within their design limitations. Power Tool Accessories and Attachments There’s a variety of accessories available for use on or with power tools.
Powered Abrasive Wheel Tools Powered abrasive grinding, cutting, polishing, and wire buffing wheels create special safety problems because they may throw off flying fragments.
Powered Abrasive Wheel Tools To prevent the wheel from cracking, the user should be sure it fits freely on the spindle. Powered Abrasive Wheel Tools Portable grinding tools need to be equipped with safety guards to protect workers not only from the moving wheel surface, but also from flying fragments in case of breakage. Portable Circular Saws Among professionals, the circular saw is probably the most commonly used power saw and perhaps the most commonly abused. Portable Circular Saw Safety Precautions Always wear safety goggles or safety glasses with side shields complying with the current national standard and a full face shield when needed.
Portable Circular Saw Safety Precautions For maximum control, hold the saw firmly with both hands after securing the workpiece. Portable Drills Available in a variety of types and capacities, portable power drills are undoubtedly the most used power tools.

Portable Drill Safety Precautions Check carefully for loose power cord connections and frays or damage to the cord.
Pneumatic Tools Pneumatic tools are powered by compressed air and include chippers, drills, hammers, and sanders.
Pneumatic Powered Tools Pneumatic power tools shall be secured to the hose or whip by some positive means to prevent the tool from becoming accidentally disconnected. Pneumatic Powered Tools The manufacturer’s safe operating pressure for hoses, pipes, valves, filters, and other fittings shall not be exceeded, The use of hoses for hoisting or lowering tools shall not be permitted. Pneumatic Tools A safety clip or retainer must be installed to prevent attachments, such as chisels on a chipping hammer, from being unintentionally shot from the barrel.
Caring for the Compressed Air System Using pneumatic tools requires an efficient compressor system to adequately power the tools.
Contaminates in the Compressor System The most common problem is water in compressed air All air contains a certain amount of moisture and impurities which can cause problems when it condenses in the air.

Wrenches, including adjustable, pipe, end, and socket wrenches shall not be used when jaws are sprung to the point that slippage occurs.
Employees and employers have a responsibility to work together to establish safe working procedures. Floors should be kept as clean and dry as possible to prevent accidental slips with or around dangerous hand tools. Some examples: Using a screwdriver as a chisel may cause the tip of the screwdriver to break and fly, hitting the user or other employees. Employers should caution employees that saw blades, knives, or other tools be directed away from aisle areas and other employees working in close proximity. Where this hazard exists, spark-resistant tools made from brass, plastic, aluminum, or wood will provide for safety. With enhanced tool performance comes the responsibility to address power-tool safety issues. There are several types of power tools, based on the power source they use: electric, pneumatic, liquid fuel, hydraulic, and powder- actuated. Among the chief hazards of electric-powered tools are burns and slight shocks which can lead to injuries or even heart failure. Gloves, if kept clear of rotating parts, and safety footwear are recommended during use of electric tools. Before an abrasive wheel is mounted, it should be inspected closely and sound- or ring-tested to be sure that it is free from cracks or defects. The spindle nut must be tightened enough to hold the wheel in place, without distorting the flange.
Because of their handiness and application to a wide range of jobs, drills often receive heavy use. A tool retainer shall be installed on each piece of utilization equipment which, without such a retainer, may eject the tool.
Safety clips or retainers shall be securely installed and maintained on pneumatic impact (percussion) tools to prevent attachments from being accidentally expelled. Working with noisy tools such as jackhammers requires proper, effective use of hearing protection.
Screens must be set up to protect nearby workers from being struck by flying fragments around chippers, riveting guns, staplers, or air drills. Several basic guidelines should be followed to insure efficient and continued operation of the compressor.
To ensure the best connection, clear any dirt off the nipple before connecting the air hose to the tool.

If cracked, there will be a dead sound and not a clear ring.?Comparison of the sound with other wheels of the same lot and specification will allow rejection of any wheel with a suspiciously different ring. For viewing only, you can play with our flash based presentation viewer instead of downloading the ppt file. Impact tools, such as drift pins, wedges, and chisels, shall be kept free of mushroomed heads.
If a hazardous situation is encountered, it should be brought to the attention of the proper individual immediately. If a wooden handle on a tool such as a hammer or an axe is loose, splintered, or cracked, the head of the tool may fly off and strike the user or another worker. A lower tensile strength means the metal has less strength or resistance to tearing apart when stretched under test conditions.
Maintenance management professionals and technicians responsible for specifying and using power tools have a responsibility to check out a tool’s safety features, then ensure that manufacturer safety precautions and common sense are followed at all times. The user and the tools are protected in two ways: by normal insulation on the wires inside, and by a housing that cannot conduct electricity to the operator in the event of a malfunction.
Choosing the wrong accessory or using an accessory incorrectly can result in serious injury. Unplug tools before installing, adjusting and changing any accessory or attachment of any kind. The main one is the danger of getting hit by one of the tool’s attachments or by some kind of fastener the worker is using with the tool.
When using pneumatic tools, employees must check to see that they are fastened securely to the hose to prevent them from becoming disconnected. Bush was running for president, he stood foursquare in defense of each person's medical, financial and communications privacy.
The wooden handles of tools shall be kept free of splinters or cracks and shall be kept tight in the tool. It also means that these tools are softer, wear down more quickly than ordinary steel tools, and have to be dressed more frequently. They should understand the potential hazards as well as the safety precautions to prevent those hazards from occurring. Disconnect tools when not in use, before servicing, and when changing accessories such as blades, bits and cutters. Care must be taken to assure that the spindle wheel will not exceed the abrasive wheel specifications. Don’t wear loose clothing, jewelry or dangling objects, including long hair, that may catch in rotating parts or accessories.
Eye protection is required and face protection is recommended for employees working with pneumatic tools. Hose and hose connections used for conducting compressed air to utilization equipment shall be designed for the pressure and service to which they are subjected. A short wire or positive locking device attaching the air hose to the tool will serve as an added safeguard. When the tool is connected, check the hose and all connections for leaks or damage before using the tool. Impact tools such as chisels, wedges, or drift pins are unsafe if they have mushroomed heads. Due to the possibility of a wheel disintegrating (exploding) during start-up, the employee should never stand directly in front of the wheel as it accelerates to full operating speed. When you start the saw, allow the blade to reach full speed before contacting the workpiece. When installing or changing a blade, be sure the blade and related washers and fasteners are correctly positioned and secured on the saw arbor. Before starting a circular saw, be sure the power cord and extension cord are out of the blade path and are long enough to freely complete the cut.
When making a partial cut, or if power is interrupted, release the trigger immediately and don’t remove the saw until the blade has come to a complete stop.
Filters, regulators, and lubricators should be used to keep the air system working at its best. A sudden jerk or pulling on the cord can cause loss of control of the saw and a serious accident. Is the speed marked on the blade at least as high as the no-load RPM on the saw’s nameplate? Be sure to use the proper size air hose and fittings to keep air pressure at a maximum throughout the entire line.
Forcing the drill can cause the motor to overheat, damage the bit and reduce operator control. Safetychapterpartlecturenotes robotic workshop safety practices that provide information technology.
