Safety Precautions

Store in a cool, dry place away from direct sunlight. Use materials compatible with ethylene glycol, such as HDPE or stainless steel, and ensure proper ventilation during handling to minimize inhalation exposure. Personnel should wear appropriate PPE including gloves and goggles, and follow established handling procedures to prevent skin or eye contact. Keep containers tightly closed when not in use and segregate from strong oxidizers to reduce compatibility risks.

Harmonized SDS data indicate the product carries a WARNING signal with hazards including Harmful if swallowed (H302) and potential organ damage from prolonged or repeated exposure (H373). In case of exposure, follow standard first-aid guidelines: eyes—rinse cautiously with water for several minutes; skin—wash with soap and water; inhalation—move to fresh air and seek medical attention if symptoms persist; ingestion—rinse mouth and seek medical advice if unwell. In case of spill or leakage, ventilate area and contain with absorbent material, preventing entry to drains. Transport is classed as UN 3082, Environmentally Hazardous Substance, liquid, n.o.s., Class 9, PG III.
