Two-Hand Control Systems Toolbox Talk

Two-hand control systems are used on machines where hands must stay out of the danger area during a cycle. Presses, benders, cutters, punches, shears, crimpers, and similar equipment can crush, cut, pinch, or amputate fingers if an operator reaches into the point of operation at the wrong time.

This talk focuses on using two-hand controls correctly, checking that both controls work as designed, and never bypassing the system to speed up the job. The purpose is simple: both hands stay on the controls until the hazardous motion is complete or stopped.

Why This Matters

• Two-hand controls help keep the operator’s hands away from blades, dies, jaws, rams, clamps, and pinch points.
• The system only protects workers when both controls are used correctly and at the same time.
• Bypassing one control can allow a hand to enter the danger zone during machine movement.
• Other workers may be exposed if they reach into the machine while the operator starts a cycle.
• Most serious injuries happen during setup, feeding material, clearing jams, adjusting parts, or repeating a task too quickly.

Common Hazards

• Taping, tying, wedging, clamping, or holding one control down so the machine can run with one hand.
• Standing too close to the point of operation while pressing the controls.
• Reaching into the machine before the ram, blade, jaw, die, or clamp has fully stopped.
• Using controls that are loose, sticky, damaged, slow to reset, or positioned too close to the danger area.
• Allowing helpers to feed, adjust, or remove material while the operator controls the cycle.
• Changing machine setup without checking that the controls still keep hands outside the hazard zone.
• Using rented, older, or unfamiliar equipment where the two-hand controls respond differently than expected.

Safety Checklist

Before Work Begins

• Confirm the operator is trained and authorized to use the machine and its two-hand control system.
• Inspect both controls for damage, sticking, loose mounts, missing labels, or signs of being taped, tied, or modified.
• Test the controls before production to confirm both must be pressed together for the machine to cycle.
• Check that releasing either control stops or prevents hazardous motion as designed.
• Make sure guards, barriers, light curtains, emergency stops, and other safety devices are in place and working.
• Set up material supports, stops, clamps, or guides so hands do not need to enter the point of operation.

During Work

• Keep both hands on the controls until the machine cycle is complete or hazardous motion has stopped.
• Do not tape, block, clamp, hold down, or bypass either control for any reason.
• Keep helpers and other workers out of the point of operation and pinch zone during each cycle.
• Use tools, push sticks, tongs, fixtures, or clamps to position or remove material when needed.
• Wait for the blade, ram, die, jaw, clamp, or moving part to fully stop before reaching near the work area.
• Stop the machine and follow lockout procedures before clearing jams, changing dies, adjusting guards, or performing maintenance.
• Report any control that sticks, fails to reset, cycles unexpectedly, or does not stop the motion as designed.

Crew Talking Points

• What machines on site today use two-hand controls?
• Who is authorized to operate those machines?
• What test should be done before the first cycle to confirm both controls are working correctly?
• Where are the pinch points, point of operation, and no-reach areas during the machine cycle?
• What should helpers do instead of reaching into the machine while the operator is at the controls?
• Does anyone have a question or concern about the two-hand controls, machine setup, or safe feeding process?

Stop Work If

• Either control is taped, blocked, wedged, clamped, tied down, modified, or slow to reset.
• The machine cycles with only one control pressed or cycles without both controls being pressed together.
• Releasing one control does not stop or prevent hazardous motion as designed.
• Workers need to reach into the point of operation during the machine cycle.
• Guards, barriers, emergency stops, light curtains, or other safety devices are missing or not working.
• The operator is unsure how the two-hand control system works or how to test it before use.

Final Reminder

Two-hand controls protect hands only when both controls are used the right way. Never bypass them, never reach into the machine during a cycle, and stop work if the system does not respond correctly.
