context_page_description: Machine guarding is a safety feature on or around manufacturing or other engineering equipment consisting of a shield or device covering hazardous areas of a machine to prevent contact with body parts or to control hazards like chips or sparks from exiting the machine. Machine guarding provides a means to protect humans from injury while working nearby or while operating equipment. It is often the first line of defense to protect operators from injury while working on or around industrial machinery during normal operations. In the U.S., machine guarding is referred to in OSHA's CFR 1910.212; in the U.K., machinery safety is covered mainly by PUWER."
context_section_description: Packaging Equipment or pallet wrappers have a moving load and an arm that stretches plastic wrap around the load.  Typically a three sided wire partition guard is placed around the wrapper, and a light curtain controls access to the open side where the wrapper is accessed by a lift truck.
  Robotic Welding Cells incorporate wire mesh fixed barriers outfitted with vinyl welding curtains and light curtains or pressure sensitive mats. The welding curtains mounted inside of the fixed barrier control exposure to welding flash, sparks and spatter from the welding operation. While the light curtain or pressure sensitive mats prevent welding operations while the operator is loading/unloading the weld fixtures. 
  Robotic Material Handling for pallet pack or de-palletizing could use any of the aforementioned guarding systems. Light curtains or pressure sensitive mats around the perimeter of the work area that stop the robot when an operator enters. Wire partition could be used around the work area with an interlocked gate which stops the robot when opened.
