Polyethylene glycol PEG-200 is classified as low toxicity and non-hazardous chemical, but basic industrial hygiene standards must still be followed, with particular attention to eye protection, hygroscopic storage prevention, and spill control.

Hazard Overview

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.

Handling and Personal Protection

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.

Storage Requirements

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.

Emergency Response Measures

First Aid Measures

  • Skin contact: Remove contaminated clothing and immediately flush the affected area with plenty of water and soap. If irritation persists, seek medical attention.
  • Eye contact: Immediately flush eyelids with plenty of water for at least 15 minutes. If irritation persists or vision is affected, seek medical attention immediately.
  • Inhalation: Move the person to fresh air and keep them breathing comfortably. If breathing difficulties occur, administer oxygen. If symptoms persist, seek medical attention.
  • Ingestion: Rinse mouth with water. Do not induce vomiting. Seek medical attention immediately and show the product container or label.

Firefighting Measures

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.

Spill Handling

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

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.
