Hand & Power Tools

Hand Tools
 
A hand tool is any tool that is powered by hand rather than a motor. Categories of hand tools include wrenches, pliers, cutters, files, striking tools, struck or hammered tools, screwdrivers, vises, clamps, snips, saws, drills and knives.

1. It is important to maintain hand tools in good working condition. The following precautionary measures will be kept in view:
• Wooden handles shall be kept free from splinters and cracks.
• Wooden handles for hammers and sledgehammers shall be secured with tapered wedges.
• Steel wedges, spanners, hammers, etc, shall be free from burrs.
• Non-sparking brass tools, chisels, etc, should be trimmed down to prevent "mushrooming" the head of the tool.
2. Files should have proper handles. Avoid using files with bare tangs. 
3. Always wear eye protection while using striking tools.
4. While using a hammer to strike a spanner, chisel, etc, the tool being hit shall not be held by hand. Always hold a striking tool in place with rope, stiff wire loop, or other means to keep the hands away from being hit by the hammer. 
5. Following 5 basic safety rules can prevent all hazards involved in the use of tools:
• Keep all tools in good condition with regular maintenance (CHECK INSPECTION STICKERS).
• Use the right tool for the right job.
• Inspect each tool for damage before use.
• Operate according to the manufacturer’s instructions.
• Provide and use the proper PPE.
6. The greatest hazards posed by hand tools result from misuse and improper maintenance. The tool may also become unsafe to use. In fact, it is estimated that hand tool mishaps are responsible for about 1 out of 12 workplace injuries-including cuts and bruises, punctures, fractures, even loss of finger, hand, or eye. Some examples to misuse:
• Using a screwdriver as a chisel may cause the tip of the screwdriver to break and fly, hitting the user or other employees.
• If a wooden handle on a tool such as a hammer is loose, splintered, or cracked, the head of the tool may fly off and strike the user or another worker.
• A wrench must be used if its jaws are sprung, because it might slip.

Power Tools 

While using power tools a large number of accidents occur, largely due to human error and deficiencies in Earthing. If proper precautions are followed, these accidents can be minimized considerably. 
 

• Employees have the responsibility for properly using and maintaining tools.
• Appropriate PPE should be worn due to the hazards that may be encountered while using portable tools.
• Avoid dangerous environments. Don’t use power tools in a damp, wet and/or explosive atmosphere.
• Around flammable materials, sparks produced by iron and steel hand tools can be ignition source. Where this hazard exists, use spark-resistant tools made from brass, plastic, aluminum, or wood.
• Employees should be trained in the use of all tools-not just power tools. They should understand the potential hazards as well as the safety precautions
• If you’re a power tool user:
• Never carry a tool by the cord or hose.
• Never yank cord/hoses to disconnect from receptacle.
• Keep cords/hoses away from heat/oil, sharp edges.
• Disconnect tools when not in use, before servicing, when changing accessories such as blades/bits cutters.

Employees using electric tools must be aware of several dangers; the most serious is the possibility Electrocution

Among the chief hazards of electric-powered tools are burns and slight shocks, which can lead to injuries or even heart failure.

Hazards Associated With Tools: 

Often times we overlook the hazards associated with the common tools that are used on a daily basis. With this talk we hope to bring some awareness to the potential hazards of these tools and how to minimize these hazards.

Pre-Inspection Use (Done before every use):

• Damaged or cracked housing, power source, or bits/accessories
• Dull blades are often more dangerous than sharp blades
• Missing guards or protective devices
• Leaking gasoline, oil or other fluids
• Tool appears to be in poor condition
• Does the tool have a 3 wire cord, if not is it double insulated?
• Ensure area is free of any potential trip hazards
• Do not underestimate the importance of a clean work area

Proper Use:

• Ensure you are wearing the correct PPE
• You should always wear eye protection
• Use the proper tool for the job
• Follow the manufacturer’s instructions
• If unsure about use, ask a supervisor or coworker for clarification
• Insure tools are not pointed at or operated in close proximity to other individuals.
• Use spark resistant tools when working near a fuel source
• Do not use excessive force to cut/drill through hard materials
• Gasoline/Mixed Fuel Powered Tools must be off and cool when re-fueled, use only in well ventilated areas.
• If you need to use a gas/mixed fuel powered tool indoors please contact supervisor / Safety department prior to use.

Training:

• Each employee using hand and portable power tools must receive initial training and an annual refresher.

Storage:

• Drain fluids (gasoline) if equipment will be in storage for an extended period of time
• De-energize tool prior to storage (includes removing air pressure, hydraulic pressure and removing loads).
• Store electric tools in dry areas
• Store flammables in accordance with applicable regulations.

 Group Discussions:

• Has anyone in the group been injured by a power tool or had a close call? How could this injury have been prevented.
• What tools present the greatest hazard in your work environment? How can you minimize these risks?
• Are there any tools that need to be repaired or discarded? If so take time to do this immediately after the talk
