Chromium fluoride (CrF3), hydrate (9CI) - Safety
Open Data Verified Data
Because of the low solubility of this product, the acute toxicity caused by chromium is low. Due to the decomposition of hydrogen fluoride and other toxic gases, we must pay attention to its toxicity, corrosive. Patients who inhale vapor should be removed from the contaminated area, placed to rest and kept warm. The eyes were washed with water for 15 min when they were stimulated. For skin contact, rinse with water and then wash thoroughly with soap. The patient was immediately sent to the hospital for treatment. See other chromic anhydride. Closed operation, strengthen ventilation. Operators must be specially trained and strictly follow the operating procedures. It is recommended that operators wear self-suction filter dust masks, wear safety full protection glasses, wear anti-corrosion work clothes and wear chemical-resistant gloves. Dust should be avoided. Avoid contact with acids. Handling should be light and light unloading, to prevent packaging and container damage. Emergency treatment equipment for leakage shall be provided. Harmful substances may remain in the empty container. Store in a cool, dry, ventilated warehouse, away from heat sources and fire. With oxidant, flammable and acids Isolation storage and transportation. Packaging and storage of polyethylene plastic bottles, each bottle of net weight lkg, or with polyethylene plastic bags lined with iron drum packaging, net weight 25kg per barrel, the package has a clear "corrosion products" signs. Risk code: other corrosion products. GB 8.3 class 83002. UN No. 1757 (solids), 8145 (liquids);IMDG CODE, P. 8.2, category 1. When a fire occurs, fire is extinguishing with water, foam and carbon dioxide, and dry sand.
