High Pressure Leak Hazards 9
Operator Manual v 2.6 — April 2012 Safety Summary
2.3.2 High Pressure Leak Hazards
• Hydraulic System
Flexible hose connections and piping in hydraulic systems must be properly tightened
to prevent the release of fluids or gases under pressure. Hoses must be inspected
periodically for signs of sweating and/or blistering. Steel tubes should be tested using
dye penetrant.
• Skin Puncture Injuries
High pressure hydraulic spray can penetrate human tissue and cause severe bodily
injury. Seek immediate medical help in any event of skin puncture by fluid spray.
2.3.3 Burn Hazards
• Hot Surfaces
The mold area, auxiliary mold equipment, and injection unit heating elements have
numerous high temperature surfaces. At normal operating temperatures, contact with
these surfaces will cause severe skin burns. These areas are clearly marked with safety
signs. Wear personal protective equipment when working in these areas.
• Molten Material
Never touch process material purged or otherwise flowing from the nozzle, mold, hot
runner or feed throat area. Molten material can appear cool on the surface, but remain
very hot on the inside. Wear personal protective equipment when handling purged
material.
2.3.4 High Pressure Explosion Hazards
Pressure can build up in a nozzle or feed throat area and cause some process material to
explode. In some cases, molten material can be ejected unintentionally due to insufficient
pre-drying or degradation of process materials. These areas are clearly marked with safety
signs. Be aware of these areas. Wear appropriate personal protective equipment when
accessing these areas.
2.3.5 Electrical Hazards
Molding equipment draws high power. The electrical requirements are indicated on the
electrical nameplate on the electrical cabinet, and in the electrical schematics. Connect
equipment to a suitable power supply as specified in the electrical schematics and in
compliance with all applicable local regulations.
WARNING!
High pressure spray hazard – risk of death or serious injury. High pressure hydraulic oil
spray can penetrate human tissue and cause extensive injuries. Lock out and tag the
machine before servicing any hydraulic component.
