Handling Precautions
Slight irritant to skin and eyes. Irritating in case of inhalation. Hazardous in case of ingestion. Ethylene Glycol is not compatible with oxidizing agents, strong acids, strong bases, aliphatic amines, isocyanates, chlorosulfonic acid, and oleum. Ethylene Glycol should be kept away from sources of ignition, smoking, and open flames.
Packaging
Bulk
Storage
If trace iron or color contamination is of concern, a stainless steel, aluminum, or epoxy liner storage vessel is recommended. A nitrogen blanket with slight positive pressure is recommended to prevent trace water or the accumulation of trace impurities through oxidation. The freezing point of ethylene glycol is -13°C, and heating or insulation is recommended at cold temperatures. Contact with rubber, zinc, copper, and tin are not recommended.
