Polyether F-68 (Poloxamer 188) can be used safely under normal industrial hygiene conditions, but safety regulations must still be strictly followed during operation. According to GHS classification, this product falls into Skin Corrosion/Irritation Category 2, Serious Eye Damage/Eye Irritation Category 2A, and Specific Target Organ Toxicity (Single Exposure) Category 3, which may cause respiratory irritation. Its pictogram is GHS07 (Exclamation mark), and the signal word is "Warning". The main hazards include: H315 Causes skin irritation, H319 Causes serious eye irritation, and H335 May cause respiratory irritation.
Although Polyether F-68 is generally safe, operators should avoid direct contact, especially in workplaces where dust is generated. When heated or burned, the product may release carbon monoxide, carbon dioxide, and other irritating or toxic vapors, so it should be kept away from high temperatures and ignition sources. In daily operation, establishing good ventilation conditions and personal hygiene habits are the foundation for ensuring safety.
| Protection Area | Specific Requirements |
|---|---|
| Respiratory System | When dust or vapors are generated, wear an approved dust/particulate mask; use appropriate respiratory protection equipment when ventilation is insufficient. |
| Hands | Wear protective gloves certified to chemical protection standards (e.g., nitrile rubber or chloroprene gloves), and check glove integrity regularly. |
| Eyes/Face | Wear sealed chemical safety goggles or a full face shield to prevent splashes and dust contact. |
| Skin and Body | Wear appropriate chemical protective work clothes to avoid exposed skin. |
Operations should be carried out in well-ventilated areas or environments with local exhaust ventilation to reduce the accumulation of dust or vapors. Eating, drinking, or smoking is prohibited during operation. After work, thoroughly wash hands and exposed body parts with soap and plenty of water immediately. When handling, minimize mechanical agitation and dust generation, and avoid inhaling dust. Work clothes should be washed regularly and not taken out of the work area. Eyewash stations and emergency showers should be available in the workplace.
Keep containers tightly closed and store in a cool (recommended temperature below 25°C), dry, and well-ventilated area. Keep away from high temperatures, heat sources, sparks, open flames, and incompatible substances such as strong oxidizers. The storage area should have an impermeable floor and be equipped with dikes or secondary containment to prevent spill spread. Avoid prolonged exposure to humid environments to prevent product caking or degradation. Store separately according to chemical storage regulations, and do not store with food, feed, or beverages.
| Emergency Situation | Response Measures |
|---|---|
| Inhalation | Move the patient to fresh air and keep in a comfortable position; if respiratory irritation, coughing, or difficulty breathing occurs, seek immediate medical attention. |
| Skin Contact | Immediately remove contaminated clothing and wash thoroughly with plenty of soap and warm water; if skin irritation or rash occurs, seek medical attention. |
| Eye Contact | Rinse immediately with running water or saline solution for at least 15 minutes; if wearing contact lenses, remove safely after 5 minutes of rinsing and continue rinsing; if irritation persists, seek ophthalmologist care. |
| Ingestion | Rinse mouth with water, do not induce vomiting; immediately drink 1-2 glasses of water to dilute; if unwell, call a poison control center or seek medical attention immediately. |
| Spillage | Wear protective equipment, cover and collect with inert absorbent materials (sand, vermiculite, etc.), transfer to a chemical waste container; prevent entry into drains, surface water, or soil. |
