International Chemical Safety Cards VINYL FLUORIDE ICSC: 0598 Vinyl fluoride (inhibited) Fluoroethene Fluoroethylene C2H3F Molecular mass: 46.1 (cylinder) ICSC #    0598 CAS #     75-02-5 RTECS # YZ7351000 UN #        1860 (inhibited) October 08, 1997 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Extremely flammable. NO open flames, NO sparks, and NO smoking. 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. EXPLOSION Gas/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. In case of fire: keep cylinder cool by spraying with water. EXPOSURE  •INHALATION Dizziness. Nausea. Shortness of breath. Ventilation, local exhaust, or breathing protection. Fresh air, rest.  •SKIN ON CONTACT WITH LIQUID: FROSTBITE. Cold-insulating gloves. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes.  •EYES (See Skin). Safety goggles, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Consult an expert! Ventilation. NEVER direct water jet on liquid (extra personal protection: self-contained breathing apparatus). Fireproof. Separated from strong oxidants. Cool. Store only if stabilized. R: S: UN Hazard Class: 2.1 UN Subsidiary Risks: SEE IMPORTANT INFORMATION ON BACK ICSC: 0598 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards VINYL FLUORIDE ICSC: 0598 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS COMPRESSED LIQUEFIED GAS , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance may polymerize freely. The substance decomposes on heating and on burning producing toxic gases (hydrogen fluoride). OCCUPATIONAL EXPOSURE LIMITS: TLV not established. OSHA PEL: none NIOSH REL: TWA 1 ppm C 5 ppm use 1910.1017 NIOSH IDLH: No data ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: A harmful concentration of this gas in the air will be reached very quickly on loss of containment. EFFECTS OF SHORT-TERM EXPOSURE: The liquid may cause frostbite. Exposure may result in unconsciousness. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: This substance is probably carcinogenic to humans. PHYSICAL PROPERTIES Boiling point: -72°C Melting point: -161°C Solubility in water: none Relative vapour density (air = 1): 1.6 Flash point: Flammable Gas Auto-ignition temperature: 385°C Explosive limits, vol% in air: 2.6-21.7 ENVIRONMENTAL DATA N O T E S Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
