  1. Automotive Shop SafetyR. Bortignon

  2. Personal Protective Equipment • eye protectionmustbe worn in the shop at all times!

  3. Two types of eye protection you can use… • safety glasses: must be worn at all times • face shield

  4. Use ear protection… • air chisel

  5. Hand Protection

  6. Protecting Your Lungs… If you are replacing brake friction material or a clutch, vacuum the dust with a hepa filter vacuum and wash down the area with water/brake cleaner before working… DO NOT USE COMPRESSED AIR! Brake linings & clutch discs may containasbestos!

  7. Protecting Your Lungs Exhaust “donuts” & some cylinder head gaskets contain asbestos!

  8. Do’s and Don'ts • No open-toed shoes • Closed toe footwear only! • Remove any rings, watches, bracelets or long necklaces before working in the shop (can cause burns, shock, and pull you into rotating parts!) • Coveralls or a shop coat should be worn

  9. Long hair needs to be tied back!

  10. Exhaust Gases Carbon Monoxide is… • Colorless • Odorless • Deadly • When we run a vehicle in our shop, we have to protect ourselves by using theexhaust retraction system • How do you turn it on?

  11. Exhaust Retraction System

  12. Air Guns & Sockets • When using the air gun, use theblack impact sockets… • Not the chrome sockets!

  13. Dangers Under the Hood… • radiator fans (2 types)… • electric • belt driven

  14. Burn Hazards! The following items can cause burns to your hands or face… • radiator cap • coolant is >100°C • coolant is pressurized • don’t remove it unless it’s cold to the touch! • exhaust manifold • exhaust gases are >1000°C • catalytic converter • very hot

  15. Fire Hazards Flammable or combustible items… • fuel • oil/lubricants • cleaning solvent: (use rubber gloves) • WD40, paint etc. must be stored in aflammable materials cabinet not like this…

  16. Brake Fluid • Is a very special fluid with certain properties, such as… • Poisonous • Harmful to your eyes (wash with water) • Hygroscopic (absorbs moisture, which can ruin your brakes over time • Will also eat paint when left in contact with it

  17. Air Conditioning Never disconnect air conditioning lines Contact with Freon will cause burns to your skin and permanent eye damage Burning Freon gas creates Phosgene gas which causes permanent respiratory damage.

  18. Fuel Vapors & Fires • Anytime the fuel system is disconnected (fuel tank, carburetor, fuel pump, fuel injectors etc.),fuel vaporsare present. Prevent fires by… • disconnecting the negative battery terminal • keep sparks away from the fuel vapors • watch those working around you • have a fire extinguisher nearby

  19. Gasoline Safety Do not use gasoline as a solvent. Use a solvent/varsol as a cleaning agent (still flammable). Only store gasoline in approved containers and in small quantities. Use caution when transferring gasoline. Do not weld on a vehicle with a damp/leaking fuel line or fuel tank. Never start a gasoline siphon with your mouth. Never add fuel to an engine while cranking. Never look down a carburettor if the car is running.

  20. Electrical Equipment Do not use electrical equipment that has a frayed or damaged cord. Make sure all electrical equipment is off before you plug it in. Do not leave or use electrical equipment on wet floors. Do not play with drop cords. Do not overload power tools. Use caution with trouble lights - electrically hot socket; may break and start fire if contacted with gas. Unplug by pulling on plug, not the cord.

  23. Painting • Must be done in a well ventilated area • Away from flames and sparks • Never put an aerosol can in the fire, it will explode!

  24. Other Fire Hazards… • Oily, greasy or fuel soaked items must be placed in the fire-proof rag container when you are finished using them! • Change out of gas/oil soaked overalls/clothing • Keep coveralls clean to prevent spontaneous combustion

  25. Batteries • Are always to be considered dangerous • Contain acid, give off explosive gasses, and can electrocute you!

  26. Battery Safety • Keep all sparks/flames/naked flame light sources away from hydrogen gas which is produced by a charging battery. • Always have the battery charger unplugged prior to connecting or disconnecting it. • Always disconnect battery when welding on a vehicle • Do not use top of battery as a tool storage. • Use proper method for connecting or disconnecting a battery charger, jumper cables and battery cables. • Keep battery acid away from clothes, skin and vehicle paint. • Do not boost a dead 6V battery with a 12V one (you may damage the other cars electrical system) • What to do if battery explodes. • Get the person to sink and wash and rinse skin and/or eyes • Wash vehicle with water

  27. Battery Cables • *Always* disconnect the *ground (-)* cable first.. (black one) • *Connect * the ground cable *last*. Jumper Cables • *Connect* jumpers to dead battery (keep other end of cables separated). • (Red = +, Black = -) • *Connect* other end (red lead = +) of good battery and (black = -) to engine block or frame of vehicle with good battery.

  28. Grinder / Wire Wheel • Always wear eye protection. • Always keep tool rest adjusted close as possible (2mm or 1/8”). • Keep fingers away from wheel and hold small parts with vise grips. • Always use the tool rest to support the work. • Never wear gloves. • Stand to one side when starting the grinder. • Allow grinder to reach full operational speed before using. • Allow grinder to come to a stop on it’s own, do not press on the wheel to slow down the wheel.

  29. Hand tools should… • …never be left on the floor • …be kept clean of oil and dirt • …be kept clear of rotating machinery • …never be placed on top of a battery (BOOM!) • …only be used for their intended purpose

  30. Please Remember… • You should use the correct tool, and size of tool • Defective tools are to be reported to the Teacher • A pull is safer than a push

  31. Tripping & Slipping Hazards • sweep & mop shop floor as you work & at the end of the lab! • floor dry is to be used for large oil spills only • keep shop floor free of tripping hazards • storage of parts? • Done with tools?

  32. Compressed Air • do notuse compressed air to clean off clothes & skin • at 4”, 40 PSI can rupture an eardrum, cause a brain hemorrhage or death • 12psi can pop an eyeball from its socket • 4psi in the mouth can rupture a lung or intestine • compressed air entering a small wound on the hand has been known to inflate the arm to the size of a grapefruit • Near the ears can cause pressure changes and hearing loss • Never look into the “business” end! • Never point it towards your body! • Use caution when hooking up air lines • Watch for tripping hazard from air lines • Never spin bearings with compressed air

  33. Eye Wash Station Do you know where it is & how to use it?

  34. Engines (before starting) • Check that they contain oil & coolant • Check under the hood for loose tools, parts, wires, etc • Attach and turn on the exhaust extractor fan • Do Not attempt to start it if there is a gas leak • Do Not prime the carb with gas in the shop • Report anything unusual to your instructor

  35. Parking Vehicles in Automotive Shops • automatic transmission: in park with parking brake on • manual transmission: in neutral with parking brake on

  36. Moving Vehicles in & Around the Shop • Who will move vehicles? • L? • N? • Teacher? Ask Mr Jurica first. • Procedures for starting engines & moving cars in/around shop • Lock-out procedures for cars with inoperative brakes, steering etc.? • Leave the drivers side window rolled down/keys on dash (can’t lock keys inside and can hear instructions) • No radios at any time.

  37. Jacks and Safety Stands Always use safety stands when working on a raised vehicle. Make sure jacks are properly located before lifting. Ensure jack can adjust position when lifting (wheels are free to roll) Block the wheels that are touching the ground.

  38. Creeper Boards • Mechanics use them to scoot around under vehicles • Do Not leave them on the ground, stand them up when not on them • Do Not push them under a car, you may drive over it

  39. Equipment& Power Tools Receive permission to use equipment. Do not use equipment that you have not had instruction in its use. Use all safety devices provided with each piece of equipment.

  40. Hoists Permission? Clean lift area/position arms in position. Drive into correct position for vehicle balance. Block wheels ( drive on hoist ). Make sure lift bars and blocks are properly located before you start the lift. Check lift points/doors/hood to ensure no damage to the vehicle! After lifting just off of ground, rock to check stability. After work is done, clear area with a visual and verbal Raise the car slightly to disengage the safety locks Be sure all safety-locks release before lowering a car from the wheel free position.

  41. Hoist Safety

  42. This is not the end! Safety will be stressed in every lesson where it is applicable. You will be expected to act -at all times- in a safe and responsible manner in this shop. If you behave in a manner that seems likely to harm yourself or others, you will be removed from this course at once.

  43. Please note… You may not leave the school grounds, or go for a test drive during class time without your instructors permission. Only those students who hold a FULL, valid drivers license may operate a vehicle, in any manner.
