3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
municipal waste incinerator flue gas Identification of halogenated organic acid [published in the British] / Mowrer J.; Nordin J. / / Chemosphere.-1987, 16 (6) .- 1181 ~ 1192 "Analysis of Chemical Abstracts" 1989.3

5. Environmental standards :

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leak contaminated areas, restricting access. Recommended emergency personnel wearing self-Pressurized respirators to wear protective clothing. Do not direct contact with leakage. A small leak : Dust to avoid using cleaner shovel collection in a dry, clean, covered containers. Large Leak : plastic sheeting, canvas cover and reduce dispersion. Then the collection, recycling or shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : its possible exposure to vapor, must wear self-absorption filter respirators (full cover). Its possible exposure to dust, it is recommended to wear headgear electric powered air-purifying respirators and dust.
eye protection : Respiratory Protection has been protective.
physical protection : Cruise-wear protective clothing 52,400.
hand protection : Acid and Basic Resistance wearing rubber gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, thorough cleansing. Overalls are not allowed to bring non-work areas. Separate storage of toxic pollution by the clothes, washed standby. To maintain good health habits.

three, and emergency measures

contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed skin, for medical treatment.
eye contact : Did eyelid, mobile or saline irrigation water and medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. If breathing is difficult, give oxygen. If breathing stop immediately mouth. Medical treatment. Fresh into
: the symptoms. Gastrolavage to blues or egg white. Medical treatment.

fire fighting methods : firefighters are required to wear gas masks, body wear firefighting suits. Extinguishant : atomised water insoluble anti-bubble, carbon dioxide, sand.
