Series of Safety Presentations include:

1 = Facility

2 = Shop Equipment + Tools

3 = Vehicle Lifting

4 = Personal Protective Equipment

5 = Fire Safety + Hazmat

shop equipment and safety
Shop Equipment and Safety
  • Always be safety conscious.
  • Accidents are often the result of carelessness or ignorance.
shop equipment and safety continued
Shop Equipment and Safety(continued)
  • Reduce obvious hazards:
    • Slippery floors.
    • Obstructed walkways.
    • Frayed electrical cords.
    • Broken equipment.
machinery safety
Machinery Safety
  • Do not disturb anyone who is operating machinery.
  • Do not talk to others while you are operating machinery.
  • Use common sense.
air compressors
Air Compressors
  • Make sure a pressure relief valve is installed on the compressor.
  • Inspect air hoses and fittings before use.
compressed air safety
Compressed Air Safety
  • Never direct compressed air at yourself or others.
  • Compressed air entering the bloodstream can be FATAL.
  • Wear eye protection.
hydraulic presses
Hydraulic Presses

Be extremely careful using a press:

  • Parts can explode under the 20–50 tons of pressure applied.
hydraulic presses continued
Hydraulic Presses (continued)
  • Use safety guards.
  • Wear eye protection.
  • Watch for sudden pressure increases with no movement of the work.
question
Question
  • An engine needs to be moved. Technician A says two people can slide the engine out of the way. Technician B says that an engine crane should be used. Who is correct?
  • Technician A only
  • Technician B only
  • Both Technicians A and B
  • Neither Technician A nor B
    • B = use an engine crane (cherry picker)
welding equipment
Welding Equipment
  • Make sure appropriate helmet is worn.
  • Protective gloves and clothing are needed to protect against hot metal particles.
safety tips for technicians
SAFETY TIPS FOR TECHNICIANS

FIGURE 1-7b A commercially available hood clamp. This tool uses a bright orange tag to help remind the technician to remove the clamp before attempting to close the hood. The hood could be bent if force is used to close the hood with the clamp in place.

FIGURE 1-7a A crude but effective method is to use locking pliers on the chrome-plated shaft of a hood strut. Locking pliers should only be used on defective struts because the jaws of the pliers can damage the strut shaft.

caution

CAUTION

Electric Cooling fans can start at any time – on their own!

electrical shock
Electrical Shock
  • Most shop equipment operates on 110 or 220 volts.
  • Turn off tools before unplugging.
electrical shock continued
Electrical Shock(continued)
  • Make sure electrical cords are in good condition.
  • Plugs need to be the three-prong type.
  • Use correctly grounded three-prong sockets and extension cords to operate power tools.
slide17

The Fatal Current

Strange as it may seem, most fatal electric shocks happen to people who should know better.

Here are some electro-medical facts that should make you think twice before taking that last chance.

slide18

It's The Current That Kills

Offhand it would seem that a shock of 10,000 volts would be more deadly than 100 volts. But this is not so! Individuals have been electrocuted by currents of 110 volts and by as little as 12 volts direct current.

The real measure of shock's intensity lies in the amount of current (amperes) forced though the body, and not the voltage.

Any electrical device used on an automobile, under certain conditions, can transmit a fatal current.

slide19

It's The Current That Kills

While any amount of current over 10 milliamps (0.01 amp) is capable of producing painful to severe shock, currents between 100 and

200 mA (0.1 to 0.2 amp) are lethal.

Currents above 200 milliamps (0.2 amp), while producing severe burns and unconsciousness, do not usually cause death if the victim is given immediate attention.

slide20

It's The Current That Kills

From a practical viewpoint, after a person is knocked out by an electrical shock it is impossible to tell how much current has passed through the vital organs of his body.

Artificial respiration must be applied immediately if breathing has stopped.

battery safety
Battery Safety
  • Avoid sparks around batteries, as they contain explosive hydrogen gas.
  • Remove the battery ground cable first and connect it last.

  • All of the above
    • D = all of the above
grinding
Grinding
  • Wear full face shield.
  • Make sure the tool rest is adjusted properly.
  • Do not grind on the side of the wheel.
drilling
Drilling
  • Bits can break.
  • Chips of metal are constantly present.
  • Do not hold work in your hand.
  • Wear eye protection.
hand tools
Hand Tools
  • Make sure the tool is in good condition.
  • Pull a wrench or ratchet towards you; never push.
  • Regrind worn chisels.
knowlede check2
KNOWLEDE CHECK

Two technicians are discussing the safe use of a wrench. Technician A says that a wrench should be pulled toward you. Technician B says that a wrench should be pushed away from you. Which technician is correct?

  • Technician A only
  • Technician B only
  • Both Technicians A and B
  • Neither Technician A nor B

Answer: A

creepers

  • Don’t leave creepers on the floor – laying flat
    • Somebody could accidentally stand on it and go flying!
    • ALWAYS STORE STANDING UP
solvents
