Health hazards: water or steam after release toxic and corrosive fumes. Heating points to explain the high toxicity of bromide fumes. The eyes, skin and mucous membranes have a strong irritant and corrosive. Two, toxicology information and environmental behavior hazardous characteristics: heating water or heat liberation and emit toxic corrosive flue gas. For many metals, particularly with the presence of moist air resistance. Combustion (decomposition) products: hydrogen bromide, phosphorus oxide. Edit this paragraph Emergency treatment and disposal methods a leakage contingency isolation leak contaminated areas, restricting access. Recommended emergency personnel wearing self-contained breathing apparatus to wear anti-acid. Do not direct contact with leakage. A small leak: Dust to avoid using cleaner shovel collection in a dry, clean, covered containers. Large Leak: plastic sheeting, canvas cover and reduce dispersion. Cleared under the guidance of experts. Two protective measures respiratory protection: its possible exposure to dust, must wear headgear electric powered air-purifying respirators and dust. Emergency rescue or evacuation,Adidas Predator Blue XI TRX FG Cleats Red for men Soccer Cleats, wear self-contained breathing apparatus. Eye protection: Respiratory Protection has been protective. Protective clothing: wear rubber acid suit. Hand protection: Wear rubber gloves acid. Other: work site prohibit smoking, eating and drinking. Overalls are not allowed to bring non-work areas. Workshop should be equipped with first aid equipment and medicines. Workers should learn self-help and mutual aid. Three, and emergency measures contact with the skin: immediately stripped of contaminated clothing, rinse with plenty of water for at least 15 minutes. Doctor. Eye contact: immediately filed eyelid, with a large number of mobile water or saline thoroughly washed at least 15 minutes. Doctor. Inhalation: rapidly from the scene to fresh air. Keep the airway patency. If breathing is difficult,2012 Adidas F50 MiCoach FG 2012 White Yellow Black Soccer Cleats, give oxygen. If not breathing, give artificial respiration. Doctor. Fresh into: oral intake of water, non-corrosive symptoms of gastric lavage. Jifu oils. Doctor. Fire fighting methods: firefighters must wear body acid firefighting suits. Extinguishing Media: dry,2013 Football Boots Soccer Cleats Shoes Adidas Adipure Cheap 11Pro XTRX FG White Black Orange , sandy soil. Do not use water.
