When using GP-330, focus on protecting eye/skin contact, controlling storage temperature at 5–35°C, keeping away from strong oxidizers, and operating in a ventilated environment.

Detailed Explanation

Polyether defoamer GP-330 is a nonionic surfactant with strong physiological inertness. Under normal usage conditions, it poses no significant hazards, but may cause mild mechanical irritation to skin and eyes. Conduct a process risk assessment before operation, ensure use in a well-ventilated area, and avoid prolonged direct contact. Emergency eyewash stations and safety showers should be available near the work area.

It is recommended to wear certified chemical safety goggles and impermeable gloves (nitrile or neoprene), along with standard protective work clothing. Thoroughly wash hands and exposed skin after operation. Prevent product overflow or splashing, and avoid entry into drainage systems, surface waters, or soil.

Emergency Measures

  • Skin Contact: Remove contaminated clothing, wipe off with a dry cloth first, then thoroughly wash with soap and water. Seek medical attention if irritation persists.
  • Eye Contact: Hold eyelids open and rinse with flowing water for at least 15 minutes. Seek medical attention promptly.
  • Inhalation of Thermal Decomposition Fumes: Move to fresh air, maintain breathing comfort. Seek medical attention if symptoms persist.
  • Ingestion: Do not induce vomiting. Rinse mouth with water and seek medical attention immediately.
  • High-temperature Processing: Ensure ventilation to prevent accumulation of thermal decomposition fumes; wear an organic vapor/particulate filter respirator if necessary.

Notes

Although this product has strong physiological inertness and is not flammable, thermal decomposition may produce irritating fumes such as carbon monoxide and carbon dioxide. It has low toxicity to aquatic organisms. Do not discharge directly into water bodies without treatment. Dispose of waste through qualified incineration facilities or as industrial waste in compliance with local regulations.
