1. Hand and Power Tool Safety

2. DIFFERENCE BETWEEN Hand Tools AND Power Tools 4 Hand tools Have no power source, other than the physical force applied by the user. Hand- tools include anything from axes to hammers, and screwdrivers to wrenches. 4 Power Tools Require a non-human power source to function properly--e.g. External (electricity, compressed air, etc.) or Internal (battery pack, internal combustion engine, etc.).

3. 4 Both kinds of tools require specific safety precautions or rules to be followed; yet some rules will apply to both. all 4 There are some basic rules that apply to all tools used either hand or power.

4. 4 Keep all tools in good working order only 4 Use the tool only for what it is designed to do 4 Examineeach use 4 Examine the tool for damage before each use 4 Always 4 Always follow the manufacturer’s instructions when operating any tool 4 Wear proper apparel. Do not wear loose clothing, dangling objects or jewelry. Long hair must be restrained. Gloves should not be worn when operating most power tools. Check with Mr. Lobmeyer General Safety Precautions

5. 4 Appropriate personal protective equipment should be worn due to hazards that may be encountered while using portable power tools and hand tools. 4 Floors should be kept as clean and free of materials as much as possible to prevent accidental slips with or around dangerous hand tools.

6. Hand Tools misuse 4 Hand tools are non-powered. They include anything from axes to wrenches. The greatest hazards posed by hand tools result from misuse and improper maintenance.

7. Hand Tool Misuse misuse 4 The greatest hazards posed by hand tools result from misuse and improper maintenance. 4 Some examples: 4 Using a screwdriver as a chisel may cause the tip of the screwdriver to break and fly, hitting the user or others. 4 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. 4 Wrenches must not be used if the jaws are sprung, cracked or twisted 4 Impact tools such as chisels, and wedges are unsafe if they have mushroomed heads. The heads might shatter on impact, sending sharp fragments flying.

8. SAFETY RULES For SPECIFIC Hand Tools 4 Use a claw hammer for pulling nails 4Do not strike a hardened steel surface with a claw hammer 4 Do not strike one hammer against another hammer 4 Do not use a hammer as a wedge or pry-bar

9. SAFETY RULES For Hand Tools cont’d 4The greatest hazards posed by hand tools result from misuse and improper maintenance. 4Use only chisels that are sharp 4Do not use chisels with a mushroomed head 4Use only hammers that are designed for use with chisels.

10. SAFETY RULES For Hand Tools cont’d 4Always ensure the screwdriver fits the head of the screw 4Do not hold the work piece against your body while using the screwdriver 4Do not use a screwdriver as a punch, chisel, pry bar or nail puller 4Do not use a screwdriver to make a starting hole for screws

11. SAFETY RULES For Hand Tools cont’d 4Do not carry the saw by the blade 4Do not use any saw that has a dull saw blade 4Keep control of the saw by releasing downward pressure at the end of each stroke

12. Today’s Power Tools 4 Offer more power, adaptability and dependability than ever before. 4 With enhanced tool performance comes the responsibility to address power-tool safety issues. 4 Students are responsible for safety when using power tools and have a responsibility to check out a tool's safety features, then ensure that the safety precautions and common sense are followed at all times.

13. Hazards of Power Tools 4 All hazards involved in the use of power tools can be prevented by following five basic safety rules: 4 Keep all tools in good condition with regular maintenance. 4 Use the right tool for the job. 4 Examine each tool for damage before use. 4 Operate according to the manufacturer's instructions. 4 Provide and use the proper protective equipment.

14. General Safety Guidelines for Power Tools 4 Power tools can be hazardous when improperly used. 4 There are several types of power tools, based on the power source they use: 4 electric, pneumatic, liquid fuel, hydraulic, and powder- actuated. 4 Students will be trained in the use of all tools - not just power tools. They should understand the potential hazards as well as the safety precautions to prevent those hazards from occurring.

15. General Safety Guidelines for Power Tools 4 The following general precautions should be observed by power tool users: 4 Never carry a tool by the cord or hose. 4 Never yank the cord or the hose to disconnect it from the receptacle. 4 Keep cords and hoses away from heat, oil, and sharp edges. 4 Disconnect tools when not in use, before servicing, and when changing accessories such as blades, bits and cutters.

16. General Safety Guidelines for Power Tools 4 All observers should be kept at a safe distance away from the work area. 4 Secure work with clamps or a vise, freeing both hands to operate the tool. 4 Avoid accidental starting. Students should not hold a finger on the switch button while carrying a plugged-in tool.

17. General Safety Guidelines for Power Tools 4 Be sure to keep good footing and maintain good balance. 4 The proper apparel should be worn. No loose clothing, ties, or jewelry they can become caught in moving parts. 4 All portable electric tools that are damaged shall be reported to Mr. Lobmeyer and removed from use.

18. Power Tool Accessories and Attachments 4 There's a variety of accessories available for use on or with power tools. 4 Caution must be exercised when selecting and using any accessory with any power tool. 4 Choosing the wrong accessory or using an accessory incorrectly can result in serious injury. 4 Unplug tools before installing, adjusting and changing any accessory or attachment of any kind.

19. Portable Drill / Drill Press Safety Precautions 4 Check carefully for loose power cord connections and frays or damage to the cord. Replace damaged tool and extension cords immediately. 4 Be sure the chuck is tightly secured to the spindle. This is especially important on reversible type drills. 4 Tighten the bit securely as prescribed by the teacher. The chuck key must be removed from the chuck before starting the drill. A flying key can be an injury-inflicting missile.

20. Portable Drill Safety Precautions 4 Check auxiliary handles, if part of the tool. Be sure they are securely installed. Always use the auxiliary drill handle when provided. It gives you more control of the drill, especially if stalled conditions occur. Grasp the drill firmly by insulated surfaces. 4 Always hold or brace the tool securely. Brace against stationary objects for maximum control. If drilling in a clockwise -- forward -- direction, brace the drill to prevent a counterclockwise reaction. 4 Don't force a drill. Apply enough pressure to keep the drill bit cutting smoothly. If the drill slows down, relieve the pressure. Forcing the drill can cause the motor to overheat, damage the bit and reduce operator control.

21. Disc / Belt Sander Safety Rules 4 Wear safety glasses or a face shield when using the sanders. 4 Only 1 person may use each sander at a time. 4 Hold the material firmly in your hands and on the table when sanding. 4 Keep fingers away from the abrasive surfaces on the sander. 4 Sand on the downward motion side of the disc sander. 4 Clean up the sander and the floor around the sander when completed

22. Band Saw Safety Rules 4 Wear safety glasses or a face shield when using the band saw. 4 Keep fingers away from the blade and out of the blade’s path when cutting. 4 Do not allow hands across the saw line when operating the band saw. 4 When the cut is almost complete, ease up on the forward pressure.

23. Band Saw Safety Rules 4 If the blade breaks, keep clear of the blade, shut off the power, and notify the teacher. 4 When backing out of a cut stop the saw, when blade stops, pull wood out slow and carefully. 4 Clean up the band saw and the floor around the band saw when completed.
