Definition of Point of Operation

The point of operation is the area on a machine where work is actually performed on the material being processed, such as where a saw cuts, a press punches or bends metal, a drill bores or a shear slices. Because this is where the machine applies its greatest force to the workpiece, it is one of the most dangerous areas of any machine and a common source of amputations.

OSHA's general machine guarding standard, 29 CFR 1910.212(a)(3), requires the point of operation of machines whose operation exposes an employee to injury to be guarded. The guard must prevent the operator from having any part of their body in the danger zone during the operating cycle.

Key Facts About the Point of Operation

  • Machine hazards are usually grouped into three areas: the point of operation, power transmission parts and other moving parts.
  • Guarding methods include fixed guards, interlocked guards, adjustable guards, light curtains, two-hand controls and pullback devices.
  • Hand tools such as push sticks supplement guarding but don't replace it.
  • Mechanical power presses have their own point of operation rules in 29 CFR 1910.217.
  • Removing or bypassing a point of operation guard is a frequent cause of serious injury and OSHA citations.

Example of a Point of Operation

On a press brake, the point of operation is between the punch and the die where sheet metal is bent. The shop installs a light curtain so the ram stops if the operator's hands break the beam while the brake is cycling.

How to Safeguard the Point of Operation

  1. Identify the point of operation on each machine during a machine guarding assessment.
  2. Select a guard or safeguarding device that keeps hands out of the danger zone.
  3. Ensure guards can't be easily removed or bypassed.
  4. Train operators on safe feeding and ejection methods.
  5. Inspect guards before use and lock out machines before clearing jams.

Frequently Asked Questions: Point of Operation

What is a point of operation guard?

It is any guard or safeguarding device that prevents a worker's body from entering the area where the machine works on the material while the machine is running.

Are light curtains acceptable point of operation guards?

Yes, when correctly installed at the proper safety distance and integrated into a control system that reliably stops the machine before a hand can reach the danger zone.

Why is the point of operation so dangerous?

It concentrates the machine's cutting, crushing or shearing force exactly where an operator's hands tend to be when feeding or positioning material.
