High purity industrial products boron tribromide
Warning - high purity industrial products boron tribromide in the wet air in the fierce smoke, the case of water reaction to produce boric acid, and release of hydrogen bromide gas.
In the sampling, testing, handling and other processes to pay attention to take protective measures. Contact with boron tribromide should wear glasses, masks, rubber gloves and other protection
Utensils. Do not contact with water, avoid inhalation of steam, contact with skin and mucous membranes. When a leak occurs, apply sediment or lime treatment, such as contact
Skin, should immediately rinse with plenty of water.
