Safety Considerations

• 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.
  

• Electrical checks
