What safety precautions should be observed when using Defoamer FAG470?

Defoamer FAG470 is classified as a non-hazardous chemical with high safety, but general industrial chemical handling procedures should still be followed, with particular attention to personal protection, storage conditions, and emergency measures.

Detailed Explanation

Defoamer FAG470 is a non-ionic emulsion defoamer based on polyether-modified polysiloxane technology. According to the Safety Data Sheet (SDS), this product is not classified as a hazardous chemical under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). No hazard categories are assigned, and no pictograms, signal words, hazard statements, or precautionary statements are required. The product is non-flammable, poses no risk of spontaneous combustion or explosion, is non-oxidizing, has no known acute toxicity, skin corrosion/irritation, or serious eye damage/irritation, and is not hazardous to the aquatic environment, making it relatively safe to use.

Despite its high safety profile, it is recommended to wear appropriate personal protective equipment (PPE) such as protective gloves and safety glasses during handling to avoid contact with eyes, mucous membranes, and prolonged skin contact. Hands and other potentially contaminated areas should be washed promptly after handling. Eating, drinking, or smoking in the work area should be avoided. When handling this product, handle with care to avoid splashing or generating large amounts of mist, and ensure adequate ventilation.

Storage Requirements

Proper storage is critical to ensure product stability:

• Store in a cool, dry, and well-ventilated warehouse, away from direct sunlight and heat sources.
• Keep containers tightly sealed to prevent moisture absorption, evaporation, or external contamination.
• Recommended storage temperature is between 5°C and 40°C. Avoid freezing or prolonged exposure to high temperatures, which may affect product stability.
• Keep away from incompatible materials such as strong oxidizers, strong acids, and strong bases; store separately.
• The storage area should be equipped with appropriate spill containment equipment, and the floor should be kept clean to prevent slips and other accidents.
• Use promptly after opening.

Emergency Measures

Skin Contact

Immediately remove contaminated clothing and wash the affected area with plenty of water and soap. If irritation or discomfort occurs, seek medical attention.

Eye Contact

Immediately flush eyes with plenty of running water or saline solution for at least 15 minutes, lifting eyelids to ensure thorough rinsing. If discomfort persists, seek medical attention immediately.

Inhalation

Move the person to fresh air and keep the airway clear. If feeling unwell, seek medical attention promptly.

Ingestion

Rinse mouth with water; do not induce vomiting (unless instructed by medical personnel). Immediately bring the product label and SDS to a doctor.

Spill Handling

Stop the source of the leak. Use inert absorbent materials (e.g., sand, vermiculite) to contain and collect the spill into designated containers for disposal according to local regulations. Avoid generating dust or allowing the material to enter drains or waterways during cleanup.

Fire Fighting

Although this product is not flammable, it may decompose under fire conditions, producing harmful fumes. Firefighters should wear self-contained breathing apparatus and full protective clothing. Use water spray, foam, dry powder, or carbon dioxide extinguishing agents, and extinguish the fire based on the nature of surrounding materials.

Notes

• Gently stir the product before use to ensure uniformity.
• It is recommended to add the product continuously using a metering pump to the foam generation area for optimal effectiveness.
• The specific dosage should be determined through small-scale tests based on actual conditions and foam level.
• Avoid freezing during storage, as freezing may cause emulsion breakage and loss of effectiveness.
• Use promptly after opening to avoid prolonged exposure to air.
