clothing have been cleaned of material. Refer to the MSDS/SDS before using any chemicals. Repeated or prolonged skin contact
may cause sensitization. Vapor may be harmful.
FIRST AID AND PROTECTIVE EQUIPMENT
The following paragraphs provide general first aid procedures and recommendations for protective equipment to minimize the
risks from material exposure. If professional medical attention is necessary, take the Material Safety Data Sheet / Safety Data
Sheet (MSDS/SDS) for the exact material involved to the attending physician.
Skin Contact
Wear 100% nitrile gloves and lab coats to avoid skin contact. Should material come in contact with skin, wash thoroughly with
soap and cold water and immediately remove contaminated clothing and shoes. If skin is irritated, seek medical attention. Dry-
clean contaminated clothing. Discard contaminated shoes and leather products.
Eye Contact
Safety goggles should be worn to prevent accidental splashes into the eyes. If material comes in contact with the eye, flush
immediately with large amounts of water for 15 minutes, avoid sunlight, fluorescent light, and other ultraviolet light, and obtain
immediate medical attention. Eye wash facilities and a first aid kit should be readily available and close to the material.
Contact Lenses
If material splashes into the eye when contact lenses are worn, flush the eye with water immediately. Verify that flushing has
removed the contact lens from the eye. Protect eyes from light and obtain immediate medical attention. Discard contact lenses
that come into contact with liquid material.
Fume Inhalation
Remove the person to fresh air. Give artificial respiration or cardiopulmonary resuscitation (CPR) if required. If breathing is
difficult, give oxygen. Obtain immediate medical attention.

ENVIRONMENTAL CONDITIONS
TEMPERATURE
To allow optimum systems operation and optimum part quality, the temperature of the ProX 800 System's room or other
location should remain stable. The working range is 23 °C +/- 3 °C (73 °F +/- 5 °F). Any temperature fluctuation greater than 3 °C
may adversely affect parts built on the system.
The air conditioning system should maintain a temperature change of less than 1 °C per hour. The stereolithography room
should have a minimum cooling capacity of 1.4 kW. We recommend an HVAC system that changes the air two to five times per
hour. To avoid adversely affecting part quality, do not expose the ProX 800 system to direct air flow from the air conditioning
system.
Beyond the temperature range that is optimum for part quality, the system is capable of operating safely without creating a
hazard between 5 °C and 40 °C.
HUMIDITY AND ALTITUDE
The optimum humidity in the ProX 800 print chamber depends partly on the material selection, although humidity should
always be non-condensing and should not vary outside the range of 20-50% for optimum part quality with most materials.
The system can operate at higher non-condensing humidity levels but may adversely affect part quality. Review your ProX 800
material information, MSDS/SDS, product datasheet, and product labeling, for specific information on recommended humidity
levels. The ProX 800 can operate correctly up to an altitude of 1000m above mean sea level.
SOUND PRESSURE
Overall sound pressure level for this equipment will not exceed 70 dBA.
