ICSC 0685 - TRIFLUOROCHLOROETHYLENE

TRIFLUOROCHLOROETHYLENE	ICSC: 0685 (April 2002)
Chlorotrifluoroethylene Trifluorovinyl chloride

CAS #: 79-38-9

UN #: 1082

EC Number: 201-201-8

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Gas/air mixtures are 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).	Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with water spray, alcohol-resistant foam, dry powder, carbon dioxide. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Dizziness. Nausea.	Use 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		Wear safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Ventilation. Remove all ignition sources. Remove vapour with fine water spray. Personal protection: self-contained breathing apparatus.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 2.3; UN Subsidiary Risks: 2.1
STORAGE
Fireproof. Cool.
