Editor's Notes
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Welcome to the Hand and Power Tools presentation. This presentation has been specifically developed to promote understanding of hand and power tools. Please make sure you are comfortable and able to concentrate as we work our way through this presentation.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) We have very specific learning objectives for you during this presentation. Our objectives are to: Provide information required by the OSHA Standards for Hand and Power Tools as found in 29 CFR 1910 Subpart P. Equip you with the knowledge to identify the hazards associated with hand and portable power tools. Effectively communicate the specific precautions that should be taken with each type of hand and portable power tool.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Our presentation today will involve the following agenda: Section One will discuss general safety precautions for using hand and power tools. Section Two will review the proper use of hand tools. Section Three will review the various types of power tools and the hazards associated with each type, and finally; Section Four will discuss your responsibilities
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Section 1 is an overview of the hazards associated with the use of tools.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Anthropologists would suggest that the use of tools is one of the characteristics that separates us from the rest of the animal kingdom. Indeed, tools are such a common part of our lives that it is difficult to remember that they may pose hazards. All tools are manufactured with safety in mind but, tragically, a serious accident often occurs before steps are taken to search out and avoid or eliminate tool-related hazards. In the process of removing or avoiding the hazards, workers must learn to recognize the hazards associated with the different types of tools and the safety precautions necessary to prevent injuries.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) All hazards involved in the use of tools can be prevented by following five basic safety rules: Keep all tools in good condition with regular maintenance. Use the right tool for the job. Examine each tool for damage before use. Operate according to the manufacturer's instructions. Provide and use the proper protective equipment. Employees and employers have a responsibility to work together to establish safe working procedures. If a hazardous situation is encountered, it should be brought to the attention of the proper individual immediately. Employees using tools must also be provided with any personal protective equipment necessary to protect them from the hazards of falling, flying, abrasive, and splashing objects, and from harmful dusts, fumes, mists, vapors, or gases.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Section 2 will be a discussion about hand tools.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Hand tools are non-powered. They include anything from saws to wrenches. The greatest hazards posed by hand tools result from misuse and improper maintenance. Some examples would include: 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 or an axe is loose, splintered, or cracked, the head of the tool may fly off and strike the user or another worker. Impact tools such as chisels, wedges, or drift pins are unsafe if they have mushroomed heads. The heads might shatter on impact, sending sharp fragments flying. The employer is responsible for the safe condition of tools and equipment used by employees, but the employees have the responsibility for properly using and maintaining tools.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Appropriate personal protective equipment, such as safety goggles, gloves, etc., should be worn to protect against hazards that may be encountered while using portable power tools and hand tools. Safety requires that floors be kept as clean and dry as possible to prevent accidental slips with or around dangerous hand tools. Sparks produced by iron and steel hand tools can be a dangerous ignition source around flammable substances. Spark-resistant tools made from brass, plastic, aluminum, or wood will eliminate this possible source of ignition.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) In Section 3, we will review power tools.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Power tools are classified by their power source, which include: Electric Pneumatic Fuel-powered, and Hydraulic Employees must be trained in the use of all tools - including power tools. They should understand the potential hazards as well as the safety precautions to prevent those hazards from occurring. Power tools can be dangerous when improperly used. The power source of a tool will give some clues as to the safety precautions required. Let’s review each type of power tool.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) The following general precautions should be observed by power tool users: Never carry a tool by the cord or hose. Never yank the cord or the hose to disconnect it from the receptacle. Keep cords and hoses away from heat, oil, and sharp edges. Disconnect tools when not in use, before servicing, and when changing accessories such as blades, bits and cutters. All observers should be kept at a safe distance away from the work area. Secure work with clamps or a vise, freeing both hands to operate the tool. Avoid accidental starting. The worker should not hold a finger on the switch button while carrying a plugged-in tool. Tools should be maintained with care. They should be kept sharp and clean for the best performance. Follow instructions in the user's manual for lubricating and changing accessories. Be sure to keep good footing and maintain good balance. The proper apparel should be worn. Loose clothing, ties, or jewelry can become caught in moving parts.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) There are two different kinds of safety devices that are used with portable power tools; safety switches and guards. It is important that the operating controls on all handheld power tools be located to minimize the possibility of accidental operation. Let’s talk about the power switch. Safety switches are designed to prevent employee injury by automatically turning off the equipment when the employee is not using the powered tool. The most common type of safety switch is a constant pressure switch. These switches are designed to shut off power to the tool when the pressure on the switch is released. Some tools may, in addition, have a lock-on control provided it can be turned off by a single motion.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) The hazardous moving parts of a power tool must be safeguarded. Guards should be provided, as necessary, to protect the operator and others from the: Point of operation In-running nip points Rotating parts Flying chips and sparks Safety guards must never be removed For example, portable circular saws must be equipped with guards. An upper guard must cover the entire saw blade. A retractable lower guard must cover the teeth of the saw, except when it makes contact with the work material. The lower guard must automatically return to the covered position when the tool is withdrawn from the work.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Employees using electric tools must be aware of several dangers. The most serious is the possibility of electrocution. Other hazards include burns and slight shocks which can lead to injuries or even heart failure. Under certain conditions, even a small amount of current can result in fibrillation of the heart and eventual death. A shock also can cause the user to fall off a ladder or other elevated work surface. To protect the user from shock, tools must be either grounded with a three-wire cord, double insulated, or powered by a low-voltage isolation transformer. Let’s take a look at double insulated tools.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Hand-held tools manufactured with non-metallic cases are called double-insulated. If approved, they do not require grounding under the National Electrical Code. Although this design method reduces the risk of grounding deficiencies, a shock hazard can still exist. Such tools are often used in areas where there is considerable moisture or wetness. Although the user is insulated from the electrical wiring components, water can still enter the tool's housing. Ordinary water is a conductor of electricity. If water contacts the energized parts inside the housing, it provides a path to the outside, bypassing the double insulation. When a person holding a hand tool under these conditions contacts another conductive surface, an electric shock occurs. If a power tool, even when double-insulated, is dropped into water, the employee should resist the initial human response to grab for the equipment without first disconnecting the power source.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Another potential hazard is using extension cords with portable tools. In construction, these cords suffer a lot of wear and tear. When a person handling a damaged extension cord contacts exposed wires while contacting a conductive surface, serious electrical shock can result, causing a fall, physical injury, or death. Since neither insulation nor grounding protects you from these conditions, use other protective measures. One acceptable method is a ground-fault circuit interrupter.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Let’s review the general safety practices for using electric tools: Electric tools should be operated within their design limitations. Gloves and safety footwear are recommended during use of electric tools. When not in use, tools should be stored in a dry place. Electric tools should not be used in damp or wet locations. Work areas should be well lighted.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Powered abrasive grinding, cutting, polishing, and wire buffing wheels create special safety problems because they may throw off flying fragments. 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. When conducting a sound test, tap the wheel gently with a light non-metallic instrument. A sound and undamaged wheel will give a clear metallic tone or "ring." If it sounds cracked or dead, the wheel could fly apart during use. Therefore, it must not be used. To prevent the wheel from cracking, the user should be sure it fits freely on the spindle. The spindle nut must be tightened enough to hold the wheel in place, without distorting the flange. Follow the manufacturer's recommendations. Care must be taken to assure that the spindle wheel will not exceed the abrasive wheel specifications.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) 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. 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. When using a powered grinder: Always use eye protection. Always turn off the power when not in use. Never clamp a hand-held grinder in a vise.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Pneumatic tools are tools powered by compressed air and include chippers, drills, hammers, and sanders. There are several dangers encountered with the use of pneumatic tools. The main danger is getting hit by one of the tool's attachments or by a fastener the worker is using with the tool. Eye protection is required and face protection is recommended for employees working with pneumatic tools. Noise is another hazard. Working with noisy tools such as jackhammers requires proper, effective use of hearing protection. When using pneumatic tools, employees must check to see that they are fastened securely to the hose to prevent them from becoming disconnected. A short wire or positive locking device attaching the air hose to the tool will serve as an added safeguard. A safety clip or retainer must be installed to prevent attachments from being unintentionally shot from the barrel. Screens must be set up to protect nearby workers from being struck by flying fragments around chippers, riveting guns, staplers, or air drills. Compressed air guns should never be pointed toward anyone. Users should never "dead-end" compressed air guns against themselves or anyone else.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) Fuel powered tools can be dangerous due to the flammable fuels used and heat that is generated. Most fuels present an ignition source that could lead to fire if not managed correctly. In addition, employees must always be cognizant of hot areas on the equipment such as mufflers or engine parts. Failure to recognize these areas can lead to burns or other injuries. In light of these facts, always remember that fuel powered tools should be operated only by trained employees.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) With respect to Fuel Powered Tool Safety, it is important to remember the following: Always turn off the engine prior to initiating a refueling event. This will minimize any ignition sources. Make sure the equipment you are using has been properly serviced and is being appropriately maintained. If a spill or leak occurs, clean it up immediately to avoid a fire hazard, and finally, Remember to always wear appropriate personal protective equipment such as gloves and hearing protection.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) A hydraulic tool is a tool operated or effected by the action of water or other fluid of low viscosity. The fluid used in hydraulic power tools must be an approved fire-resistant fluid and must retain its operating characteristics at the most extreme temperatures to which it will be exposed. The manufacturer's recommended safe operating pressure must not be exceeded for: Hoses Valves Pipes Filters and Other fittings
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) In Section 4, we will review your responsibilities as a user of hand and portable power tools.
- Recommended Facilitator Notes: (read the following text out-loud to participants while showing this slide) All hazards involved in the use of tools can be prevented by following five basic safety rules: Keep all tools in good condition with regular maintenance. Use the right tool for the job. Examine each tool for damage before use. Operate according to the manufacturer's instructions. Provide and use the proper protective equipment. Employees and employers have a responsibility to work together to establish safe working procedures. If a hazardous situation is encountered, it should be brought to the attention of the proper individual immediately.
