6. Emergency treatment and disposal methods
a leakage contingency

cut off the fire source. Emergency personnel wearing self-contained breathing apparatus to wear general fire protective clothing. To ensure the safety of plugging. Rinse with plenty of water, diluted lotion Add to the wastewater system. If large spills, using a causeway asylum, and then to collect, transfer, recycling or waste processed sound.

two protective measures

respiratory protection : concentration in air overweight, they should wear protective masks.
eye protection : general need special protection, but suggested that under special circumstances, wearing chemical protective safety glasses.
protective clothing : wearing overalls.
hand protection : if necessary, wear protective gloves.
other : no smoking scene work. To maintain good health habits.

three, and emergency measures

contact with the skin : the pollution off clothing, with a large number of mobile water thoroughly washed.
eye contact : immediately open from top to bottom eyelid, mobile or saline irrigation water. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. Difficult to breathe oxygen. Stop breathing, artificial resuscitation immediately. Medical treatment. Fresh
income : enough to drink warm water, the symptoms and to seek medical treatment.

fire fighting methods : water mist, foam, carbon dioxide, dry, sandy soil.
