Span S-80 (Sorbitan monooleate) is a non-ionic surfactant, and its hazards primarily involve irritation to contact areas of the human body. According to the product safety data, this substance is classified as a skin irritant (Category 2, H315), a serious eye irritant (Category 2, H319), and may cause respiratory irritation (Category 3, H335). Fortunately, the product has no classification in terms of physical and chemical hazards, with a flash point above 149°C, making it not classified as a flammable liquid. Under normal storage conditions, fire risk is low, but it should still be kept away from high temperatures and open flames.
In daily operations, personnel must wear complete personal protective equipment, including protective gloves, protective clothing, safety goggles, and face shields. The work area should be well-ventilated to avoid inhaling product vapors or mist. After operation, thoroughly wash hands and any skin areas that may have come into contact with the product, and avoid contact with eyes, skin, and clothing. It is recommended to follow general industrial hygiene practices in the workplace and use explosion-proof ventilation and lighting equipment.
In case of emergency: if skin contact occurs, immediately rinse with plenty of soap and water; if eye contact occurs, rinse continuously with water for several minutes, removing contact lenses if present, and seek medical attention if irritation persists; if discomfort arises from inhaling vapors, move to fresh air quickly; if ingested, do not induce vomiting, rinse mouth immediately and seek medical attention. In case of spillage, use inert absorbent materials such as sand to contain and collect, and do not discharge into drains.
| Protection Area | Protective Measures | Risk Category |
|---|---|---|
| Skin | Wear chemical-resistant gloves, protective clothing | Category 2 — H315: Causes skin irritation |
| Eyes | Wear safety goggles or face shield | Category 2 — H319: Causes serious eye irritation |
| Respiratory System | Ensure good ventilation, wear respiratory protection if necessary | Category 3 — H335: May cause respiratory irritation |
| Whole Body | Thoroughly wash hands and contacted areas after operation | Avoid prolonged or repeated contact |
Although Span S-80 is not classified as a flammable liquid, as its flash point is above 149°C, it generally does not form flammable vapors at normal operating temperatures. However, it is still recommended to keep away from heat sources, sparks, and open flames. When operating in laboratories or factories, it is advised to conduct compounding and feeding operations under a fume hood or local exhaust ventilation. In case of a spill, do not rinse directly with water; use inert materials such as sand or vermiculite to absorb and collect, then seal and dispose of properly.
