Trichloroethylene (TCE) is a man-made chemical used most commonly as a solvent in manufacturing to degrease metal parts. Water Gremlin previously used TCE to help produce battery terminals that prevent batteries from leaking. However, we have eliminated TCE from our operations.
After nearly a year of research and testing, we are now now using an alternate solvent called trans-1,2-Dichloroethylene, or t-DCE. t-DCE is a non-hazardous solvent with more favorable toxicology and ozone implications than TCE. We have a comprehensive system to monitor outdoor air concentrations of t-DCE with independent laboratory results reported directly to the Minnesota Pollution Control Agency. We measure our usage of t-DCE in real time, so we can make immediate adjustments if needed.
Our search for a viable replacement for TCE took time because most TCE alternatives are flammable, which would create a safety hazard for our workers. We are pleased that t-DCE is both non-flammable and non-hazardous. Most states do not have a permissible exposure limit for t-DCE. However, Minnesota’s limit is 35 times the limit set for TCE.
