Precautions for using OS-15 (AEO-15)?

When using OS-15 (AEO-15), special attention should be paid to preventing skin and eye irritation. Protective equipment must be worn throughout the operation, and direct discharge of the product into the aquatic environment should be avoided.

Detailed Explanation

OS-15 (AEO-15) is a nonionic surfactant, appearing as a white waxy solid. Under normal use conditions, it is non-explosive, non-flammable, and non-carcinogenic, with relatively good safety. However, according to GHS classification, this product is classified as Skin irritation category 2 (H315) and Serious eye damage/eye irritation category 2 (H319), indicating clear irritancy to skin and eyes. In addition, this product also has Aquatic chronic toxicity category 3 (H412), posing long-term harmful effects on aquatic organisms. Therefore, it is strictly prohibited to directly discharge undiluted or large quantities of the product into water bodies, sewers, or the environment.

During operation, effective impermeable gloves (such as nitrile gloves) and chemical safety goggles must be worn, along with appropriate protective clothing. The workplace should maintain good ventilation to avoid inhaling vapors or mists. Eating, drinking, smoking, and storing food are prohibited. Hands and exposed skin should be thoroughly washed after operation. Operators should receive specialized training and strictly follow operating procedures.

Emergency Treatment Measures

In case of contact, immediately take the following first aid measures:

• Skin contact: Immediately remove contaminated clothing and rinse thoroughly with plenty of running water and soap for at least 15 minutes. Seek medical attention if irritation or rash occurs.
• Eye contact: Immediately lift the eyelids and rinse thoroughly with plenty of running water or saline for 15-20 minutes, then seek immediate medical attention.
• Inhalation: Move quickly to fresh air and maintain an open airway. If breathing is difficult, give oxygen; if breathing stops, perform artificial respiration immediately and seek medical attention.
• Ingestion: Rinse mouth with water, do not induce vomiting. Immediately drink 1-2 glasses of water to dilute and seek medical attention as soon as possible.

Storage Conditions

The product should be stored in a cool, dry, well-ventilated dedicated warehouse, away from fire sources and heat, and keep the container tightly closed. The storage temperature should be maintained at 5-35°C, avoiding freezing and excessive heat. If freezing occurs, thaw naturally at room temperature; do not use an open flame to heat. Avoid storage with strong oxidizers, strong acids, and strong alkalis. The storage area should be equipped with leak collection facilities (such as trays). Empty containers may contain hazardous residues and should not be used for other purposes before thorough cleaning.

Leak Treatment

For small leaks, absorb with inert adsorbent materials (such as sand, vermiculite) and collect in a sealed container for disposal. For large leaks, build dikes or dig pits to contain the spill, cover with foam to reduce vapor dispersion, and transfer to tankers or dedicated collectors using explosion-proof pumps. Prevent leaks from entering sewers, drains, or surface water bodies; use barriers if necessary.

Precautions

• Although this product does not have special combustion or explosion hazards, irritating fumes may be released in a fire. Extinguishing media may include water mist, alcohol-resistant foam, dry powder, or carbon dioxide.
• The oral LD50 in rats is greater than 2000 mg/kg, indicating low toxicity, but ingestion should still be avoided.
• The 96h LC50 for fish (zebrafish) is 1-10 mg/L, indicating high toxicity to aquatic organisms; emissions must be strictly controlled.
• After freezing, natural thawing at room temperature can restore performance. Do not use an open flame to heat, as it may damage the product structure.
