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 and gloves. Rinse with plenty of water, diluted Add Water Wastewater System. Leak large collection shipped to recycling or waste disposal sites disposal.

two protective measures

respiratory protection : Workers should wear protective masks.
eye protection : Wear protective chemical safety glasses.
physical protection : wear protective clothing polyethylene film.
hand protection : Wear protective gloves.
other : work site prohibit smoking, eating and drinking. After work, take a shower. Pay attention to personal hygiene. Implementation of pre-employment and periodic medical examinations.

three, and emergency measures

contact with the skin : stripped of contaminated clothing, with a large number of mobile water thoroughly washed. Medical treatment.
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. Respiratory stop immediately mouth. Medical treatment. Fresh into
: coverage to persons or egg white blues. Medical treatment.

fire fighting methods : Unburning. Available around the fire extinguishing media.
