`General Shop Safety
This lesson is designed to teach students how to identify, interpret and evaluate general
shop safety.

Upon completion of the lesson, students will be able to:
   1. Identify general shop safety rules.
   2. Associate shop safety with different machines in the shop.
   3. Design a shop layout using the given information.
   4. Evaluate their shop layout and conclude why their layout is a safe shop.

Focus/Interest Approach
Begin class by showing a few of the IMS Eye Slides to the class. Explain that these
injuries might have been avoided if they had used the correct eye protection.

Lesson Content:
Safety comes first!
    Always wear safety glasses:
        o “An ounce of prevention is worth a pound of cure” when it
           comes to eye protection
        o Always wear proper eye protection when working in the shop
    No Horseplay:
        o Most accidents are caused by carelessness
        o Caused by human error
        o Refrain from getting involved in poor shop behavior:
                scuffling                            playing with tools
                tripping                             running
                pushing                              hurrying projects
                disobeying shop rules                loud talking
    Shop Layout
        o Shop should be set up for free flowing movement.
        o The shop should have plenty of ventilation.
                Doors

                  Fans
                  Vent hoods
          o Have work tables spread out and clean.
          o Have all machines spread out so students can use all of them.
          o Have easy access to fire escapes and fire extinguishers
          o Have your lumber stored in safe place.
                  Away from flames or heated areas.
                  Do not stack it in the way.
          o Have your welders set up in a well ventilated area.
                  They should be spread out for plenty of work space.
                  Welding stands should be spread out and well covered.
          o Have Oxy-Acetylene Rig stored in a safe area.
          o Do not place obstructions in front of exits
                  Such as projects.
      Machine Use:
          o Unless you have been taught to run a machine, DON’T USE IT!
          o Turn off machines when not in use or during repair.
          o Always use the proper tool for the job.
          o Avoid wearing loose or overly baggy clothing when working with
          o Be aware of people around you at all times.
      Oxy-acetylene Safety
          o Use correct shaded lens when welding.
          o Know where fire escapes and fire extinguishers are.
          o Wear heat-resistant, nonflammable gloves.
          o Keep area and clothes free from grease or oil.
          o Do not oil or grease cylinder screws.
          o Report defective material or tools to instructor
          o Welding and cutting should be done in well ventilated areas
          o Use soap and water to check for gas leaks
      Cylinder Care
          o Store or place cylinders in safe places with secure chains around them.
          o Keep sparks and flames away
          o Always store tanks with safety caps.
          o Do not use cylinders without proper pressure regulators.
          o Do not use undue force in trying to open or close a cylinder valve.
      Hose Care
          o Oxygen hoses are green, acetylene hoses are red
          o Oxygen hose fittings have right-hand threads
          o Acetylene fittings have left-hand threads
          o Never used damaged hoses.
          o Do not allow hoses to come in contact with hot metal or where sparks
              could accumulate

                 Vent hoods
                 Fans
           o Report defective material or tools to instructor

                 It could cause electrical shock
           o Make sure the welding area is well covered to protect from flashing other

Guided Practice:
Have some scenarios set up in the shop demonstrating both safe practices in the shop and
unsafe practices. Have the students walk into the shop and we will go around talk about
the different scenarios, why or why not the situation demonstrates shop safety.

Independent Practice:
Using the given worksheet have the students design their own shop layout. The have the
students evaluate the layout and conclude why their shop layout is safe.
