Safety considerations
Vol. 27 #2, November 2000

Following are some safety considerations when running an extruder:
  • Safety gates and guards should be in place.
  • Wear safety glasses at all times.
  • Wear hearing protection, if required.
  • Keep the floor free of pellets as they act as ball bearings and can cause a bad fall.
  • Avoid standing opposite the die, melt pipe and head flanges, as they can unexpectedly squirt hot polymer especially during the heat up and start up stages.
  • Avoid standing downstream from head or flange bolts and rupture disk, especially at start up. An over-pressure condition can cause a bolt to break and shoot out like a bullet. Contamination can cause rapid screen pack plugging, which the over-pressure and shutdown circuits may not safely detect.
  • Keep hands and metal items out of the feed throat. To break a pellet bridge or resin jam, use a plastic or wood rod.
  • When checking an open vent, wear a full face, clear, polycarbonate shield.
