5. Environmental standards :
former West Germany (1982) Occupational air 2mg/m3
maximum allowable concentration of rice to allow residues :

6. Emergency treatment and disposal methods :
a leakage disposal

isolation leakage polluted area, located around the warning signs, the proposed emergency personnel wearing self-contained breathing apparatus to wear chemical protective clothing. To direct contact with the spill with sand or other absorbent non-flammable mixture absorption, and then transferred to a safe place. We could also use a lot of water washing, dilution of sewage into the wastewater system. If large spills, recycling or collection of sound waste treatment.

two protective measures

respiratory protection : production operation or agricultural use, wear protective masks. Emergency rescue or escape, they should wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
protective clothing; Wear appropriate protective clothing.
hand protection : Wear protective gloves.
other : work site prohibit smoking, eating and drinking. After work, take a shower. Separate storage of toxic pollution by the clothes, washed reuse. Pay attention to personal hygiene.

three, and emergency measures

contact with the skin : contaminated clothing off with 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
: coverage, adequate drinking warm water, the symptoms. Medical treatment.

fire fighting methods : foam, powder, sand.
