How to Safely Store MEA (Monoethanolamine) Solvent?
MEA (monoethanolamine) solvent must be stored in sealed containers within a dedicated, cool, dry, and well-ventilated area. Containers should be made of corrosion-resistant materials such as stainless steel or polyethylene. Keep away from fire sources, heat sources, and incompatible substances like strong oxidizing agents and strong acids. The storage facility should be equipped with leak containment systems and neutralizing agents.
