Emulsifier S-185/O-5 is an industrial nonionic surfactant. According to its safety data, this product is classified as a skin irritant (Category 2), serious eye irritant (Category 2), and respiratory tract irritant (Category 3, single exposure). It is harmful if swallowed (acute toxicity Category 4) and is toxic to aquatic life with long-lasting effects (hazardous to the aquatic environment, Category 2). Therefore, the safety specifications for chemical handling must be strictly observed during use.
From a physicochemical hazard perspective, this product is not flammable, with a flash point greater than 150°C, but it should still be kept away from strong oxidizers and high-temperature heat sources. In routine operations, non-sparking tools should be used and anti-static measures taken. Burning may produce irritating or toxic fumes such as carbon monoxide and carbon dioxide. Suitable extinguishing agents include water spray, alcohol-resistant foam, dry powder, or carbon dioxide.
In terms of personal protection, operators should wear protective gloves, safety goggles, and protective masks, avoiding contact with skin, eyes, and clothing. After operation, hands and exposed body parts must be thoroughly washed. Eating, drinking, and smoking are prohibited during operation. In case of skin contact, wash immediately with plenty of running water and soap. For eye contact, lift eyelids and rinse with plenty of running water for at least 15 minutes. If ingested, do not induce vomiting; seek medical attention immediately.

In case of a leak, immediately wear appropriate personal protective equipment to prevent the spill from entering drainage systems, surface water, or groundwater. For large spills, contain and absorb with inert materials such as sand, vermiculite, etc. Collect absorbed material in closed containers and dispose of according to local regulations by a licensed waste treatment facility. Clean contaminated area with water and detergent.
If swallowed, immediately call a poison control center or seek medical attention. Rinse mouth with water. Do NOT induce vomiting unless instructed by medical personnel. This product is toxic to aquatic life; do not discharge untreated material into the environment.
