Partial stannate - Safety
Open Data Verified Data
meta stannic acid is a chemical powder, and its dust is harmful to human body. The main by-products of this production method are nitric oxide and industrial wastewater. Nitric oxide can be produced by water absorption; Industrial wastewater can be treated by Tianjin Research Institute of Chemical Industry. Hazard code: GB 12268-90-62001 UN NO.2814. Packaging and storage: its nature is relatively stable, the inner packaging can be used in paper bags or polyethylene plastic bags, each net weight: 20kg,50kg, etc.; The mouth of the bag is sealed with a machine; The outer packaging can be used in wooden cases or galvanized iron barrels or polyethylene plastic barrels, the lid shall be lined and fastened. Outside the package, there should be marked "moisture-proof" "anti-corrosion" text and icon identification, as well as the provisions of the text description of the goods. Store in a ventilated, dry warehouse. Waterproof, fire-proof, moisture-proof, anti-corrosion. Do not co-store with flammable and easily oxidized articles. Handling should be handled with care to avoid damage to the package, when transport to cover cloth to prevent sun and rain. Hazards and protection: Meta tin acid dust is harmful to human body. The working environment should be ventilated and clean to prevent dust accumulation in the air. Operators should have labor protection, especially to protect the respiratory system. Production and use of a large number of powder, after work to wash change clothes, protective equipment should be stored separately, often Bath. Fire can be suppressed with water or dry powder.
