3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
wastewater Triphenyl Phosphine of Determination, cattle-industry, "environmental chemicals," 8,582 5,275 (1,987)

5. Environmental standards :

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leak contaminated areas, restrict access, cut off the source of fire. Emergency personnel wearing self-contained breathing apparatus to wear chemical protective clothing. Do not direct contact with leakage. A small leak : to avoid dust, carefully scan, bag placed transfer to a safe place. Large Leak : collection, recycling or shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : high concentration environment, should wear protective masks. Emergency rescue escape, it is recommended to wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
protective clothes : wear appropriate protective clothing.
hand protection : Wear gloves against chemicals.
other : work site prohibit smoking, eating and drinking. After work, take a shower. Do not dress to a non-operational establishments, separate storage of toxic pollution by the clothes, washed reuse.

three, and emergency measures

contact with the skin : the pollution off clothing, mobile water rinse.
eye contact : eyelid filed immediately, rinse with clean water.
INHALED : from the scene to fresh air. When necessary, respirators. Medical treatment. Fresh into
: coverage to those who drink large warm water, the symptoms and to seek medical treatment.

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