  4. Repair Area • Any location in shop where repairs are performed • Shop stall • Small, sometimes marked off or numbered • Outside work area • Adjacent to shop overhead doors • Lift • Raises vehicle into air • Alignment rack • Use for working on steering and suspension systems

  5. Lift Safety • Ask instructor for demonstration • Get permission • Position vehicle’s center of gravity • Point of perfect balance • Follow service manual (Eagle Equipment)

  6. Lift Safety (Cont.) • Raise vehicle slowly • Keep fingers clear of moving parts • Double-check lift points • Make sure vehicle is level • Verify lift safety catch is engaged • Do not walk under lift without catch in fully locked position

  7. Lift Safety (Cont.) (Chrysler)

  8. Toolroom • Shop storage area for larger pieces of repair equipment • Shop tools • Small equipment • Supplies • All tools must be accounted for at end of class period • Follow instructor’s policies and procedures

  9. Classroom • Office-like area in school or large repair facility • Increase knowledge of auto service and repair • Used for seminars, demonstrations, and training activities

  10. Shop Safety • Every year, thousands of auto technicians are injured or killed • Broken safety rules • Constantly think of safety • Emergency exits • Designated escape routes

  11. Auto Shop Present Dangers

  12. Types of Accidents • Fires • Explosions • Asphyxiation (airborne poisons) • Chemical burns • Electric shock • Physical injuries

  13. Fires • Store gasoline and other flammables in approved containers • Never use gasoline as cleaning solvent • When disconnecting fuel line, cover it with rag to prevent squirting or leaking

  14. Fires (Cont.) • Wipe up gasoline spills immediately • Do not use oil absorbent (oil-dry) • Keep heat sources away from exposed fuel system parts • Disconnect batteries before working on fuel system parts • Keep batteries disconnected during repairs

  15. Fires (Cont.) • Properly store oily rags • Store combustibles in fire cabinet • Fire extinguishers • Know locations • How to properly use • Always use correct type

  16. Fire Classifications • Classified by burning material • Type A • Wood, paper, plastic, or cloth • Type B • Burning liquids • Type C • Electrical equipment • Type D • Burning metals

  17. Fire Extinguisher Types • Soda-acid • Type A fire only • Pressurized water • Type A fire only • Carbon dioxide • Type B or C fire only

  18. Fire Extinguisher Types (Cont.) • Foam • Type A or B fire only • Dry chemical • Multipurpose type (Type A, B, or C fire only) • Ordinary BC type (Type B or C fire only) • Dry chemical (granular-type material) • Type D fire only

  19. Explosions • Rapid, almost instant, combustion of material that causes powerful shock wave • Sources • Hydrogen gas around car batteries • Fuel tanks • Special sodium-filled engine valves • Welding tanks • Propane-filled bottles

  20. Explosions (Cont.) • Always wear proper eye and face protection when working around batteries • Prevents • Blindness • Facial cuts • Acid burns • Scars (Snap-on Tool Corp.)

  21. Asphyxiation • Caused by breathing in toxic or poisonous substances • Symptoms • Dizziness • Headaches • Vomiting • Death • Exhaust gases are poison • Proper ventilation

  22. Asphyxiation (Cont.) • Other harmful substances if inhaled • Asbestos • Parts cleaners • Paint spray • Working around airborne impurities • Wear proper respirator (Lab Safety)

  23. Chemical Burns • Burns to skin • Solvents • Battery acid • Corrosive substances • Decarbonizing throttle body cleaner • Wear proper protective gear

  24. Electric Shock • Result of electric current passing through parts of body • May cause injury or death • Never use tool that does not have functional ground prong • Never use an electric tool on wet shop floor

  25. Hybrid Safety • Hybrid vehicles use high-voltage motor-generator and HV battery pack • Operate on 300−600 volts • Always follow manufacturer's instructions and safety rules • Wear rubber electrician’s gloves • Use insulated tools • Disconnect or disable batteries during service

  26. Physical Injury • Result from hundreds of different accidents • Cuts • Broken bones • Strained back • Evaluate every repair technique • Take appropriate precautions • Use proper tool for job

  27. General Safety Rules • Wear eye protection • Avoid anyone who does not take safety seriously • Keep shop organized • Dress appropriately • Never carry sharp tools in pocket • Wear full face protection when grinding or welding
