1. Slide 1

   Introduction to Drill Press Safety

   • This material was produced under Susan Harwood grant number SH-31214-SH7 Occupational Safety and Health Administration, U.S. Department of Labor. The contents in this presentation do not necessarily reflect the views or policies of the U.S. Department of Labor, nor does the mention of trade names, commercial products, or organizations imply endorsement by the U.S. Government.
2. Slide 2

   Introduction: What’s a Drill Press?

   • The Drill Press, also called the Drilling Machine, is a device for producing holes in hard substances. The drill is held in a rotating spindle and is fed into the workpiece, which is usually clamped in a vise resting on a table.
   • The components of a drill press
3. Slide 3

   Introduction: Early Drill Press

   • The first drill presses appeared in blacksmith and machine workshops more than 200 years ago. They were built for cutting metal and were powered by a hand crank.
   • An early version of the drill press
4. Slide 4

   What it Does: What is a drill press used for?

   • Drill presses are primarily used to drill or enlarge a cylindrical hole in a workpiece or part such as the ones shown in the image here. They can also be used for reaming, countersinking, counterboring, and tapping.
   • An example of holes made using the drill press
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: Preventing injuries and amputations

   • To avoid getting injured:
   • Get trained and authorized to operate the Drill Press
   • Identify OFF SWITCH, EMERGENCY STOP (as seen in picture)
   • Use a drill of an appropriate size and type
   • The emergency stop button on a drill press
9. Slide 9

   Hazards: Point of operation

   • Be aware of the point of operation, which is the area on a machine where work is performed on the material being processed. The point of operation on the Drill Press cannot be completely guarded and therefore can cause injury when the users’ hands come in contact with the drill bits.
   • A chip guard is needed for protection from the point of operation.
   • The point of operation of a drill press
10. Slide 10

    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
11. Slide 11

    Hazards: Hazard Signage

    • To prevent injuries, be aware of hazard signages next to the machinery.
    • An example of hazard signage
12. Slide 12

    Hazards: Flying chips and wood dust

    • Drilling can cause chips, sparks and wood dust to fly in different directions.
    • An example of wood dust generated by drilling
13. Slide 13

    Hazards: Power transmission device

    • The power transmission device is the component which transmits energy to the part of the machine performing the work. These components can include flywheels, pulleys, belts, connecting rods, couplings, cams, spindles, chains, cranks, and gears. Severe or even fatal injuries can occur from coming into contact with hazardous energy.
    • The power transmission of this drill press
14. Slide 14

    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
15. Slide 15

    Hazards: Best practices

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