2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : the decomposition products of HF and four fluorinated silicon have a stimulating effect.

two, toxicology information and environmental behavior

hazardous characteristics : high fever, or by contact with acid or acid mist emit toxic smoke.
combustion (decomposition) products : hydrogen fluoride.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
ion selective electrode (GB7484-87, the water, fluoride)

5. Environmental standards :
China (TJ36-79) Workshop harmful substances in the air that the maximum allowable concentration 1mg (F) / m3

6. Emergency treatment and disposal methods :
a leakage disposal

wearing gas masks and gloves. Clean the shovel collection in a dry cleaner in covered containers, transported to the waste disposal sites. If large spills, recycling or collection of sound waste treatment.

two protective measures

engineering control : production process confined to enhance ventilation.
respiratory protection : Workers should wear masks. If necessary, wear gas masks.
eye protection : Wear protective chemical safety glasses.
protective clothing : wearing overalls.
hand protection : Wear rubber gloves.
other : work site prohibit smoking, eating and drinking. To maintain good health habits.

three, and emergency measures

contact with the skin : contaminated clothing off and spent a lot of water flow thorough Dr Chong.
eye contact : immediately open from top to bottom eyelid and by the flow of water or saline-washed. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. Difficult to breathe oxygen. Stop breathing, artificial resuscitation immediately. Medical treatment. Fresh into
: mouthwash immediately to the blues or egg white. Medical treatment.

fire fighting methods : water, sand, dry powder, carbon dioxide.
