2. The impact on the environment :
a health hazard

pathways : inhalation.
health hazards : contact can cause headache, nausea and vomiting, have a narcotic effect.

two, toxicology information and environmental behavior

toxicity : is low toxicity category.
acute toxicity : rats inhaled 20% x 2 hours, survival; Guinea pigs inhaled 50 ~ 80% (256 environment for inhalation), survival
hazardous characteristics : Unburning. Heating-explain highly toxic smoke.
combustion (decomposition) products : hydrogen fluoride.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods : gas chromatography
reference to the "Handbook of Analytical Chemistry" (fourth volumes, chromatography analysis), the chemical industry publishers

5. Environmental standards :
former Soviet air workshop harmful substances maximum allowable concentration 1000mg/m3

6. Emergency treatment and disposal methods :
a leakage contingency

rapid withdrawal of staff from air leakage supremacy wind and isolation and strict restrictions on access. Recommended emergency personnel wearing respirators-positive pressure self-sufficiency, wearing overalls general operations. As far as possible, cut off the source of leakage. A reasonable ventilation, accelerated proliferation. Leak containers should be properly handled, repair, testing later use.

two protective measures

respiratory protection : concentration in air material is high, since the proposed wear suction filtered gas masks (half-mask).
eye protection : general need special protection.
physical protection : general operating wear uniforms.
hand protection : Wear protective gloves general operations.
other : avoid high concentrations of respirable. Enter cans, or other restrictive space of high concentration operations, someone custody.

three, and emergency measures

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.

fire fighting methods : This Unburning. Cut off the gas source. Cooling water containers, if possible to move containers from the scene empty Department.
