PEG-200 is not classified as a hazardous chemical and has high inherent safety. In terms of health, this substance has low toxicity, with an acute oral toxicity (rat) LD50 greater than 2000 mg/kg. It causes no or only very slight skin irritation (rabbit skin irritation index 0 to 0.5), and is slightly irritating to the eyes. It is not skin sensitizing (negative guinea pig maximization test result) and not genotoxic (negative Ames test). Physicochemically, this substance is non-flammable and non-explosive. Ecologically, it has low ecotoxicity, is readily biodegradable, and is not expected to bioaccumulate.
Although PEG-200 is mild in nature, appropriate personal protective equipment, including safety goggles and protective gloves, should be worn during handling. General work clothing is sufficient. Operations should be carried out in well-ventilated areas to ensure air circulation. Avoid prolonged contact with eyes and skin during handling. Do not eat, drink, or smoke. After handling, thoroughly wash hands and exposed skin, and follow good industrial hygiene practices.
PEG-200 should be stored in a cool, dry, well-ventilated warehouse. The recommended storage temperature is 15°C to 30°C. Containers must be kept tightly sealed to prevent moisture absorption (PEG-200 is somewhat hygroscopic). Keep away from incompatible materials such as strong acids and strong oxidizing agents. Corrosion-resistant storage containers, such as stainless steel, polyethylene, or carbon steel with epoxy lining, are recommended. The storage area should be equipped with spill containment facilities.
This substance is non-flammable and non-explosive, suitable for any extinguishing medium (water fog, dry powder, carbon dioxide, foam). However, in a fire, combustion or thermal decomposition may produce irritating or toxic gases. Firefighters should wear self-contained positive-pressure breathing apparatus and full protective clothing.
For small spills, use inert absorbent material to absorb and collect in a suitable container for disposal. For large spills, contain the source of the leak to prevent entry into drains or water bodies, and use pumps or appropriate tools to transfer to a spare container for recovery or disposal. When cleaning the spill area, avoid generating excessive splashing to prevent slippery surfaces. If environmental contamination has occurred, immediately notify the local environmental protection authority. Evacuate non-essential personnel and isolate the spill area.
Disposal must comply with all national, regional, and local environmental regulations. Incineration or other appropriate treatment should be carried out at authorized waste treatment facilities. Do not discharge this substance into drains, soil, or any water bodies.
