There are significant differences in the precautions for using emulsifier OS (fatty alcohol polyoxyethylene ether/secondary alkyl sodium sulfonate) and emulsifier MS-1 (octylphenol polyoxyethylene ether maleate). Emulsifier OS is classified under GHS as skin corrosion/irritation category 2 and serious eye damage/irritation category 2. During operation, chemical safety goggles and protective gloves must be worn to avoid direct skin and eye contact. Emulsifier MS-1 has no hazard classification and is a low-risk chemical, but it is still recommended to maintain good ventilation during operation and avoid prolonged skin contact.
Both products share common requirements for operating environment management: the workplace should maintain good ventilation, eating, smoking, or drinking is prohibited in the operating area, and hands and any exposed skin should be thoroughly washed after operation. It is particularly noteworthy that emulsifier OS requires explosion-proof ventilation systems and equipment, and should be kept away from heat and ignition sources.
In terms of storage, both must be stored in a cool, dry, and well-ventilated warehouse, with containers kept sealed. Emulsifier OS must be stored separately from incompatible substances such as oxidizers and strong acids, following the first-in-first-out inventory principle. Emulsifier MS-1 should be kept away from extreme temperatures and direct sunlight, and away from strong oxidizers. Neither is classified as dangerous goods, and transport classification is non-dangerous goods.
| Precaution | Emulsifier OS | Emulsifier MS-1 |
|---|---|---|
| GHS hazard | Skin corrosion/irritation category 2; Serious eye damage/irritation category 2 | No hazard classification |
| Hazard statement | H315 Causes skin irritation; H319 Causes serious eye irritation | None |
| Personal protective equipment | Chemical safety goggles, protective gloves, work clothes (mandatory) | Recommended conventional protective gloves |
| Ventilation requirement | Explosion-proof ventilation system | Maintain good ventilation |
| Storage incompatibility | Keep away from oxidizers and strong acids | Keep away from strong oxidizers |
| Transport classification | Non-dangerous goods | Non-dangerous goods |
Emulsifier OS emergency response: In case of skin contact, immediately remove contaminated clothing and rinse with plenty of running water and soap for at least 15 minutes. In case of eye contact, hold eyelids open and rinse thoroughly with plenty of running water or saline solution for at least 15 minutes and seek medical attention immediately. If inhaled, move the person to fresh air. If ingested, rinse mouth with water, do not induce vomiting, and seek medical attention immediately. For spills, small amounts can be absorbed with inert absorbing material; for large spills, dike to prevent entry into sewers and waterways.
Emulsifier MS-1 emergency response: For skin contact, wash with soap and water. For eye contact, rinse with plenty of water for several minutes; if irritation persists, seek medical attention. If inhaled, move the person to fresh air. Small ingestions are usually harmless; for larger amounts, rinse mouth with water and consult a physician. For spills, collect into waste containers; residues can be rinsed with water; for large spills, prevent entry into waterways.
Emulsifier OS may decompose under heat in a fire, producing irritating or toxic gases. Firefighters must wear self-contained positive-pressure breathing apparatus and full fireproof clothing. Although emulsifier MS-1 is not flammable, it may also produce irritating fumes when decomposed by heat; firefighters should wear self-contained breathing apparatus and full protective gear. Both are suitable for extinguishing with water mist, dry powder, carbon dioxide, or foam.
