Tools and Safety

1. Tools and Safety

2. General Tool Safety • Wear proper eye protection, ear protection, and protective clothing. • Secure hair and loose clothing. • Work in areas with good lighting. • Make sure all personnel are at a safe distance before using the tool. • Keep tools free of oil, grease, and foreign matter. • Use the tool for its designed use. • Secure small work in a clamp or vise. • Repair or replace damaged tools. • Report any injuries to the supervisor.

3. Tool Types • Hand Tools • Hand tools are tools that are powered by hand. • Power Tools • Power tools are tools that are electrically, pneumatically, or hydraulically powered for greater efficiency when performing service and repair tasks. • Power tools can be portable or stationary. • Portable power tools can be transported with the operator. Stationary power tools cannot be transported, and are commonly installed in a fixed position. • Power tools may cause serious injury if proper safety procedures are not followed.

4. Hand Tool Safety • Keep tools sharp and in proper working order. Look for wear that could cause an injury, such as a pitted hammer face, damaged insulation on a pliers, or splintered handle. • Point cutting tools away from the body during use. • Grind excess metal from mushroomed chisels. • Organize tools to protect and conceal sharp cutting surfaces.

5. Hand Tool Safety • Never use a hammer on another hammer. The impact of the hardened surfaces may cause the heads to shatter. • Do not carry tools in a pocket. Transport sharp tools in a holder or with the blade pointed down. • Remove fasteners by pulling the tool toward the body or pushing the tool away from the face

6. Power Tool Safety • Follow all manufacturers’ recommended operating instructions. • Use UL or CSA approved power tools that are installed in compliances with the NEC. • Do not use electrical tools on or near a wet or damp area. • Use power tools that are doubled-insulated or have a third conductor grounding terminal to provide a path for fault current. • Ensure power switch is in OFF position before connecting to power source.

7. Power Tool Safety • Ensure that all safety guards are in place before starting. • Arrange cords and hoses to prevent accidental tripping. • Stand to one side when starting and using a grinder. • Stand clear of operating power tools. Keep hands and arms away from moving parts. • Use tools designed for compressed air service. • Shut off, lock out, and tag out disconnect switches of power tools requiring service.

8. Classification of Tools • Measuring • Fastening – Wrenches • Fastening – Screwdrivers • Fastening – Pliers • Cutting • Striking/Driving • Testing • Specialty Tools

9. Measuring • Feeler Gauges • Micrometer • Telescoping Gauge • Dial Caliper • Tachometer • Ruler A B C D E F

10. Measuring Tools Feeler Gauge – To verify distance between parts. Ie. The gap in a spark plug. Micrometer - measure thickness and diameter

11. Measuring Tools Telescoping Gauge – transfer distance from parts to measurement tool Dial Caliper – measure inside, outside, and depth of parts

12. Measuring Tools Tachometer – measure engine speed in RPM Ruler – Measure linear distance

13. Fastening – Wrenches • Open End • Box End • Combination • Ratchet & Socket • Adjustable • Hex • Impact • Torque A E B F C G D H

14. Wrenches Open End – Loosen/tighten bolt or nut with contact on two flats Box End – Loosen/tighten bolt or nut; less likely to slip off than open end wretch Combination- Loosen/tighten bolt or nut with convenience of open end and box end on same wrench

15. Wrenches Ratchet and Socket – Loosen/tighten bolt or nut in tight locations Adjustable – Loosen/tighten bolt or nut in tight locations Hex – Loosen/tighten hex screws

16. Wrenches Impact – Loosen/tighten bolt or nut with air or electric power with short, rapid impulses to socket Torque – Tighten bolt or nut specified torque

17. Fastening – Screwdrivers • Standard • Phillips • Torx • Offset • Hex A B C D C A B B

18. Screwdrivers Standard – Drive slotted head fastener Phillips – Drive Phillips head fastener

19. Screwdrivers Torx – Drive Torx head fastener Offset – Drive slotted, Phillips, or Torx head fasteners in tight locations

20. Fastening – Pliers A • Slip Joint • Adjustable • Locking • Needle Nose • Snap Ring D B E C

21. Pliers Slip-Joint – Grip fasteners and parts Adjustable – Grip large fasteners and parts Locking – Lock on fasteners and/or hold parts

22. Pliers Needle Nose – Grip fasteners and/or parts in tight locations Snap Ring – Install and remove snap ring fasteners
