   Introduction: What’s a band saw?

   • The Band Saw was invented by William Newberry in 1808. It is one of the most widely-used wood and metal working machines.
   • Originally for cutting wood, band saws can now cut metal if you change the blade and speed.
   • An early band saw
3. Slide 3

   Introduction: Two types of band saw

   • Here are two common types of Band Saws:
   • 1. Vertical (left)
   • Used to saw curves, lumber, irregular shapes
   • 2. Horizontal (right)
   • Use to cut long pieces, tubes
   • A vertical band saw (left) and horizontal band saw (right)
4. Slide 4

   What it Does:

   • What is a band saw used for?
   • Band Saws are able to cut a variety of materials such as metals, plastics, and wood.
   • An example of a bandsaw performing a cut
5. Slide 5

   Safety: Who is OSHA?

   • With the Occupational Safety and Health Act of 1970, Congress created the Occupational Safety a nd Health Administration (OSHA) t
   • assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance.
   • OSHA is part of the United States Department of Labor. The administrator for OSHA is the Assistant Secretary of Labor for Occupational Safety and Health. OSHA's administrator answers to the Secretary of Labor, who is a member of the cabinet of the President of the United States.

   Safety: Know your rights

   • Under federal law, you are entitled to a safe workplace.
   • employer must provide a
   • Your
   • workplace free of known health and safety hazards.
   • you have concerns, you have
   • If
   • the right to speak up about them without fear of retaliation. You also have the right to:
   • Be trained in a language you understand
   • Work on machines that are safe
   • Be provided required safety gear, such as gloves or a harness and lifeline for falls
   • Be protected from toxic chemicals
   • Request an OSHA inspection, and speak to the inspector
   • Report an injury or illness, and get copies of your medical records
   • See copies of the workplace injury and illness log
   • Review records of work-related injuries and illnesses
   • Get copies of test results done to find hazards in the workplace
7. Slide 7

   Hazards: Machine-related injuries

   • Possible machine-related injuries include:
   • Crushed fingers or hands
   • Amputations
   • Blindness
   • Blindness is a possible machine-related injury
8. Slide 8

   Hazards: Point of operation

   • The point of operation is the area on a machine where work is actually performed on the material being processed.
   • On the Horizontal Band Saw, the point of operation is either at the point where the saw blade meets the machine table or where the saw blade meets the part being cut.
   • The point of operation on a band saw
9. Slide 9

   Hazards: Power transmission device

   • Located on the top of the Horizontal Band Saw.
   • Drives the wheel that makes the saw band move.
   • Guarded and shielded to prevent any accidental contact with its moving parts.
   • The power transmission device on the band saw
10. Slide 10

    Hazards: Operating controls

    • Operating Controls house the switches and dials to operate the saw
    • Emergency Stop / off button: Shuts the machine off in an emergency if something goes wrong.
    • Green “On” button: Starts the saw.
    • Power Disconnect Button: Completely shuts the power off to the machine.
    • The operating controls on the band saw
11. Slide 11

    Hazards: Nip points and rotating parts

    • In-running nip points are commonly found among rotating or reciprocating parts. They occur in two scenarios:
    • When machine parts move toward each other
    • When machine parts run past a stationary object
    • Examples of nip points in different mechanisms
12. Slide 12

    Hazards: Flying chips and wood dust

    • Flying chips and machine coolant are likely to be thrown in different directions due to cutting action
    • An example of chips and coolant during a cut
13. Slide 13

    Hazards: What is machine guarding?

    • Machine Guard (orange part in the image) is a means of shielding employees from moving or flying parts and preventing them from accidentally coming into contact with moving pieces of equipment.
    • The orange machine guarding of a band saw
14. Slide 14

    Hazards: Preventing injuries and amputations

    • Be trained
    • Identify ON/OFF or EMERGENCY button
    • Use a blade of an appropriate size and type
    • Set the guard (open wide enough) to clear stock/workpiece
    • Secure workpiece in the vise.
    • The operating controls on a horizontal band saw
15. Slide 15

    Safe operation: Best practices

    • Identify Emergency Stop and Off switch.
    • Make sure right and left guard doors are closed.
    • Make sure all guards are in place.
    • Wear Personal Protective
    • Equipment (PPE) at all times
    • Clean up and clear work area
    • The different components of the horizontal band saw
16. Slide 16

    Hazards:

    • Lockout/Tagout
    • Lockout/tagout procedures are safeguarding methods to prevent injury due to hazardous energy sources. If you see the machines with the signs featured in the image or that are under lock and key, please stay away and do not touch or attempt to start it.
    • Examples of Lockout/tagout equipment
17. Slide 17

    Hazards: Best practices

    • Set the guard to clear stock/workpiece
    • Wear Personal Protective Equipment (PPE) at all times
    • Clean up and clear work area
