IMPORTANT SAFETY INSTRUCTIONS
WARNING: READ AND UNDERSTAND THIS MANUAL AND ITS SAFETY INSTRUCTIONS BEFORE USING THE
DENSITY. FAILURE TO DO SO CAN RESULT IN SERIOUS INJURY OR DEATH.
WARNING: THE MACHINE USES COMBUSTIBLE DUST.
Interlock Function
The interlock function features a safety switch integrated into the safety glass lid, ensuring that the water pressure function is
deactivated as soon as the lid is opened.
Customer Safety Program
Before using the Density, customers must have a safety program in place. The safety program should do the following:
• Label and point out hazardous equipment, materials, and procedures.
• Explain what to do in an emergency situation.
• Provide information about the hazards of equipment and materials in the form of Safety Data Sheets (SDSs). The SDSs are
provided with all materials supplied by 3D Systems
The information in this chapter supplements the customer's existing safety program. It points out safety considerations that
specifically concern the Density system.
Safety Symbols and Definitions
The following are safety symbols that are common to 3D Systems guides. Some or all of these symbols may appear in this guide
and/or in other Density documentation.
CAUTION: Indicates the possibility of loss of data or damage to equipment.
WARNING: INDICATES THE POSSIBILITY OF INJURY OR DEATH TO PERSONNEL.
Electrical Shock: High voltage electricity is accessible in the vicinity of this sign or behind the access panel.
High voltage can cause severe burns or death, as well as fires. Access panels are for service only and should be
opened only by certified service personnel or trained maintenance personnel.
Arc Flash: High energy electrical discharge between two electrically conductive materials. Take care to
avoid opening electrical enclosures unless electrical components are de-energized or specialized personal
protective equipment is worn.
Wear Eye Protection: Indicates the need for eye protection.
Wear Protective Mask: Indicates the need to wear an appropriate face mask.
Wear Protective Gloves: Wear the appropriate gloves when required. For example, when touching surfaces
that may contain or have been exposed to materials, wear nitrile gloves. Heat gloves are necessary when
touching surfaces that may be hot to ensure burns don't occur.
Flammable material: Flammable material when in the form of dust clouds. Take care when in the vicinity of or
handling flammable materials.
Pinch Point: Injury or death from crushing weight.
Note: A note signifies important information but not information of a critical content.
