Resin Spill Containment
The photopolymers used in stereolithography may be hazardous if handled improperly. Repeated
skin contact with resins may cause sensitization. Consult the manufacturer’s
for information on specific resins. For further information on this and related
topics, consult the
website.
Resin should be stored in opaque, non-reactive containers, according to the guidelines given in
the MSDS included with the resin. Protect resin from sunlight and ambient room light. Resin may
be stored in RDMs with the lid securely fastened. Pouring resin back into the original containers
is acceptable, but be sure to leave several inches of air above the resin in the sealed container.
This will leave room for expansion and also inhibits spontaneous polymerization for some resins.
Always label resin by type and usage history.
Never mix different resins.
Do not dump used resin 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 resin 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 resin, which can cause
eye, skin, and respiratory irritation, as well as possible skin allergies and respiratory reactions.
