It is understood: barium stearate , white or slightly yellow amorphous powder, melting point >225℃, stimulating effect on the central nervous system, soluble in hot ethanol, benzene, toluene and other non-polar solvents, insoluble in water and ethanol. It is heated and dissolved in an organic solvent and becomes a gel when cooled, and is water-absorbent in the air. No sulfide contamination. When encountering strong acid, it decomposes into stearic acid and the corresponding barium salt.
Barium stearate safety related handling and instructions:
First aid measures:
Acute toxicity : Oral administration – rat LD50: 2506 mg/kg; Oral administration – mouse LD50: 1832 mg/kg. [3]
Skin contact: Remove and isolate contaminated clothing and shoes. For small amounts of skin contact, avoid spreading the substance over an area. Keep the patient warm and quiet.
Eye contact: If skin or eyes come into contact with this substance, flush immediately with clean water for at least 20 minutes.
Inhalation: Move patient to fresh air and seek medical attention. If the patient stops breathing, give artificial respiration. If the patient ingests or inhales the substance, do not perform mouth-to-mouth resuscitation. Use a small respirator with a one-way valve or other appropriate medical respirator. If breathing is difficult, give oxygen.
Ingestion: Inhalation, ingestion or skin contact with this substance may cause delayed reactions. Ensure that medical personnel understand the personal protection knowledge related to this substance and pay attention to their own protection.
Respiratory system protection: above the NIOSHREL concentration or the REL has not been established, at any detectable concentration: self-contained positive pressure full-facepiece respirator, air-supplied positive pressure full-facepiece respirator supplemented by auxiliary self-contained Portable positive pressure respirator. Escape: Full-face mask high-efficiency particulate air purifying respirator, self-contained escape respirator.
Health Hazards:
High concentrations or repeated exposure can cause weakness and paralysis of the limbs, heart and respiratory system.
Hazardous Characteristics:
Contact with oxidizing agents may cause fire and explosion.
Emergency response:
If the substance or contaminated fluid enters the waterway, notify downstream users of potential water contamination and notify local health and fire protection authorities. officials and pollution control authorities.
Fire extinguishing methods:
Use dry powder, alcohol-resistant foam, and carbon dioxide to extinguish fires. Use water mist to cool exposed containers from a safe distance away. If the cooling water flow does not work (the discharge volume and tone increase, the tank changes color or shows any signs of deformation), evacuate to a safe area immediately.
Storage matters:
