6. Emergency treatment and disposal methods

a leakage contingency

isolation leakage polluted area, located around the warning signs, cut off the source of fire. Recommended emergency personnel wearing self-contained breathing apparatus to wear chemical protective clothing. The use of non-sparking tools carefully So, to avoid dust, transported to the waste disposal sites. Wash leakage polluted water, diluted Add Water Wastewater System. If large spills, recycling or collection of sound waste treatment.

two protective measures

respiratory protection : Workers must wear protective masks. If necessary, wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
protective clothing : wearing antistatic dress.
hand protection : Wear gloves against chemicals.
other : work site prohibit smoking, eating and drinking. After work, take a shower. Pay attention to personal hygiene.

three, and emergency measures

contact with the skin : use soap and water thoroughly washed. Medical treatment.
eye contact : opened eyelids, mobile water rinse for 15 minutes. Medical treatment.
INHALED : from the scene to fresh air. Medical treatment. Fresh into
: adequate coverage who drink warm water, the symptoms. Medical treatment.

fire fighting methods : dry powder.
