CATEGORY
PRECAUTION
Fire/Heat
• Never smoke or ignite anything around powdered
materials.
• Maintain proper clearance from materials when using
portable heating devices.
• Store flammable liquids away from materials.
• After removing a part from the print chamber, allow it to
cool to room temperature in a well-ventilated area.
• Use anti-static mats in front of SLS equipment.
Inhalation
• Avoid breathing powdered materials, when exposure to
dust or fumes is likely, wear a NIOSH- approved respirator
appropriate to the airborne concentration.
• Always provide adequate ventilation.
Shop Safety
• Train operators in SLS system procedures.
• Wear safety glasses.
• Use extreme care with all heated materials.
