3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :

5. Environmental standards :

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leakage polluted area, located around the warning signs, the proposed emergency personnel wearing gas masks, chemical protective clothing to wear. Do not spill direct contact with sand, dry lime or soda ash mixture, then collect and transport the waste to disposal sites. If large spills, recycling or collection of sound waste treatment.

two protective measures

respiratory protection : high concentration environment, should wear protective masks. When necessary, wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
protective clothing : wearing overalls (anti-corrosion material).
hand protection : Wear rubber gloves.
other : work, take a shower. Pay attention to personal hygiene.

three, and emergency measures

contact with the skin : the pollution off clothing, immediately wash with water for at least 15 minutes.
eye contact : immediately filed eyelid, mobile or saline irrigation water for at least 15 minutes. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. When necessary, respirators. Medical treatment. Fresh into
: coverage immediately mouthwash, or egg white to the blues. Medical treatment.

fire fighting methods : water mist, foam, carbon dioxide, sand.
