The photopolymers used in stereolithography may be hazardous if handled improperly . Repeated skin contact with materials may cause 

sensitization. Consult the manufacturer’s Global Harmonized Standards/Safety Data Sheet (GHS/SDS) for information on specific 
materials . For further information on this and related topics, consult the 3D Systems – Materials website at 

Material should be stored in their original containers, according to the guidelines given in the GHS/SDS included with the material . 
Protect material from sunlight and ambient room light . 

Do not dump used material down any drains . Follow disposal rules established by company, local, state, and federal authorities .

Your company has the responsibility to define what constitutes a major spill. Personnel who are involved in cleaning up major spills 
of material should wear NIOSH/MSHA approved respirators designed for use with organic chemical vapors . In addition, each person 
should wear protective goggles, rubber boots, and 100% nitrile gloves to minimize exposure to material, which can cause eye, skin, and 
respiratory irritation, as well as possible skin allergies and respiratory reactions .

Any spilled material should be absorbed on inert absorbent material and placed into containers for transfer to an approved waste 
disposal site . After cleaning up the spill, individuals should wash thoroughly with soap and COLD water . Dry-clean contaminated clothing . 
Discard contaminated shoes and leather products . Avoid exposure to sunlight until skin and clothing have been cleaned of material . 
Refer to the GHS/SDS before using any chemicals . Repeated or prolonged skin contact may cause sensitization . Vapor may be harmful .

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 Global Harmonized Standards/Safety Data Sheet (GHS/SDS) 
for the exact material involved to the attending physician .

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 .

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 3D printer system.

If material splashes into eyes when contact lenses are worn, flush eyes immediately with water. Verify that flushing has removed the 
contact lens from the eye(s) . Protect eyes from light and obtain immediate medical attention . Discard contact lenses that come into 
contact with liquid material .

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 .
