Safe Use of Radial Arm Saws

Tools & Equipment
English (NZ)

The Problem

Radial arm saws are powerful and versatile tools that enhance productivity and work quality. However, they rank among the most hazardous saws on a job site when misused. Accidents often stem from improper setup, defective blades, or neglecting safety features. Today, we'll address these hazards and outline the steps necessary for the safe operation of radial arm saws.

Identify the Hazards

  • Improper Setup: Saws that aren't securely anchored or properly leveled can move unexpectedly, leading to accidents.

  • Damaged or Improper Blades: Blades with broken teeth, cracks, or bends increase the risk of failure or kickback.

  • Lack of Guards: Operating without correctly installed blade guards raises the chance of contact with the spinning blade.

  • Kickback: Occurs when wood binds, encounters knots, or lacks anti-kickback devices, causing the material to be thrown back toward the operator.
    ‍
  • Foreign Objects in Material: Nails, staples, or knots in the wood can damage the blade and create hazards.

Safety Practices and Preventative Measures

  1. Pre-Use Inspection:

    • Ensure the radial arm saw is level and securely anchored to prevent movement.
    • Remove any debris around the saw, and ensure no one is positioned behind it during operation.
  2. Blade Safety:

    • Use the correct blade size and speed rating for the saw and material.
    • Inspect the blade for damage, such as broken teeth or cracks, and ensure it is properly secured.
  3. Blade Guards:

    • Confirm all guards are in place and functioning:

      • Fixed Guards: Cover the arbor and upper blade.
      • Self-Adjusting Guards: Cover the lower blade during operation.
    • Never operate the saw without guards, as this significantly increases the risk of injury.
  4. Setting the Upper Travel-Stop:

    • For repetitive cuts, set an upper travel stop to limit the saw’s movement and prevent it from traveling toward you unnecessarily.
    • Adjust the saw head so the front is slightly higher than the rear, allowing it to retreat automatically when released.
  5. Prevent Kickback:

    • Install and properly adjust anti-kickback fingers on both sides of the blade.
    • Use a riving knife to keep the cut material from pinching the blade during ripping operations.
  6. Wood Inspection:

    • Carefully inspect wood for knots, nails, staples, or any foreign objects that could damage the blade or create hazards.
    • Avoid attempting cuts on materials that may cause the saw to bind or malfunction.

Real-Life Case or Scenario

Where possible, use an actual incident that you have experienced or been involved in.

A worker failed to inspect the wood before cutting and struck a nail embedded in the material. This caused the blade to break, leading to a dangerous kickback. Fortunately, the worker avoided injury, but this incident highlights the importance of inspecting materials before cutting and maintaining your blade.

Employee Responsibilities

  • Inspect the radial arm saw, blade, and work area before use.

  • Ensure all guards and anti-kickback devices are installed and functional.

  • Never operate a saw that has been improperly set up, is unstable, or has damaged components.

  • Report defective equipment immediately to your supervisor.

Employer Responsibilities

  • Provide well-maintained radial arm saws with appropriate guards and anti-kickback devices.

  • Offer training to ensure employees understand the safe operation of radial arm saws.

  • Replace damaged equipment and ensure regular maintenance.

Discussion & Questions

  • "What steps do you take to inspect a radial arm saw before use?"
  • "Has anyone encountered a safety issue while using a radial arm saw? How did you address it?"

Encourage employees to share experiences or concerns and provide clarification as needed.

Commitment/Action Plan

Starting today, let’s commit to thorough pre-use inspections and using all safety features on radial arm saws. If you see unsafe practices, step in and remind your coworker of the proper safety procedures. Safety is everyone’s responsibility.

Wrap-Up

Radial arm saws are powerful tools that can be dangerous when mishandled. By following these safety practices and adhering to WorkSafe New Zealand standards, we can prevent accidents and ensure everyone goes home safe at the end of the day. Thank you for your attention, and let’s keep safety our priority.

Standards Overview

WorkSafe New Zealand provides guidelines for the safe use of radial arm saws, including proper guarding, anti-kickback devices, and inspection protocols. Non-compliance with these standards can lead to injuries such as lacerations, amputations, or kickback incidents.
