|VINYLIDENE FLUORIDE||ICSC: 0687 (August 1997)|
| CAS #: 75-38-7
| UN #: 1959
|EC Number: 200-867-7
|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire. Gas/air mixtures are explosive. Explosive.||NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state. Use non-sparking handtools.||Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, carbon dioxide. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.|
|Inhalation||Use ventilation.||Fresh air, rest.|
|Skin||ON CONTACT WITH LIQUID: FROSTBITE.||Cold-insulating gloves. Protective clothing.||ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .|
|Eyes||Wear safety goggles.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Ventilation. NEVER direct water jet on liquid. Personal protection: complete protective clothing including self-contained breathing apparatus.||
According to UN GHS Criteria
|Fireproof. Separated from incompatible materials. See Chemical Dangers. Store only if stabilized.|

|PHYSICAL & CHEMICAL INFORMATION|
Physical State; Appearance
Formula: C2H2F2 / CH2=CF2
|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 500 ppm as TWA; A4 (not classifiable as a human carcinogen).
MAK: carcinogen category: 3
|High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
Vapours are uninhibited and may form polymers in the vents or flame arresters causing blockage.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Check for peroxides prior to distillation; eliminate if found.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
