The antistatic agent MOA3PK-70 (alcohol ether phosphate potassium salt) is a functional chemical additive. Although it is not a flammable liquid (closed-cup flash point > 100 °C), according to the GHS classification standard, this product is classified as Skin irritant Category 2 (H315: Causes skin irritation) and Serious eye irritant Category 2A (H319: Causes serious eye irritation). Oral acute toxicity LD50 (rat) > 2000 mg/kg, which does not meet the acute toxicity classification standard, but ingestion may still cause discomfort. Therefore, personal protection must be given top priority during operation.
In terms of engineering controls, the operation area should be equipped with local exhaust or general ventilation to ensure that the concentration of substances in the air is controlled. Grounding facilities should be used during transfer or dispensing, and operations should be carried out through closed pipelines or containers to prevent electrostatic accumulation. Explosion-proof tools should be used when opening containers, and operations should be slow and gentle to prevent splashing. Eating, drinking, and smoking are strictly prohibited in the work area. Operators should receive pre-job training to fully understand the hazards and emergency handling methods of this substance.
During storage, the product should be kept in a cool, dry, and well-ventilated warehouse, away from heat sources, sparks, and open flames. The container material should be corrosion-resistant, such as stainless steel, polyethylene, or polypropylene. It must be sealed after use to prevent moisture absorption. It should be stored separately from strong oxidizers, strong acids, strong bases, and food additives. The storage area should be equipped with spill containment pallets or dikes, the ground should be impermeable, and obvious safety warning signs should be set up.
| Protected Part | Equipment Requirement |
|---|---|
| Eye Protection | Wear standard chemical safety goggles or face shields |
| Hand Protection | Wear chemical-resistant protective gloves (e.g., nitrile rubber gloves); wash hands thoroughly with soap and water after contact |
| Skin and Body Protection | Wear impermeable work clothing to avoid direct skin contact |
| Respiratory Protection | In poorly ventilated areas, wear respiratory protective equipment with appropriate filter cartridges |
Skin Contact: Immediately remove contaminated clothing and flush skin with plenty of running water and soap for at least 15 minutes. If irritation persists, seek medical attention.
Eye Contact: Immediately open eyelids and rinse slowly with running water or saline for at least 15 minutes, rotating the eyeballs periodically, and seek professional ophthalmic medical assistance as soon as possible.
Inhalation: Quickly move the patient to fresh air and keep the airway clear. If breathing is difficult, administer oxygen; if breathing stops, perform artificial respiration immediately and seek emergency medical attention.
Ingestion: Immediately rinse the mouth with water; do not induce vomiting. If conscious, drink a small amount of warm water to dilute; do not give anything by mouth to an unconscious person, and seek immediate medical attention.
Spill Handling: For small spills, cover with inert absorbent material (such as dry sand, vermiculite, or universal absorbent) and collect in a covered chemical waste container; for large spills, immediately evacuate non-essential personnel, isolate the contaminated area, block sewer inlets, contain with sand or dikes, wear full protective equipment, transfer the spilled liquid to an emergency collection container using an explosion-proof pump, treat residues with absorbent, then wash the contaminated area with plenty of water and properly dispose of the wash water.
Suitable extinguishing media include carbon dioxide, dry powder, foam, or water spray. Firefighters must wear self-contained breathing apparatus and full protective clothing, and cool containers exposed to fire with water spray to prevent thermal decomposition or rupture.
