	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Highly flammable. Vapour/air mixtures are explosive.	NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.	Use powder, alcohol-resistant foam, water spray, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation		Use ventilation.	Fresh air, rest.
Skin			Rinse skin with plenty of water or shower.
Eyes	Redness.	Wear safety spectacles.	Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Remove all ignition sources. Consult an expert! Personal protection: self-contained breathing apparatus. Cover the spilled material with foam. Do NOT wash away into sewer.	According to UN GHS Criteria Highly flammable liquid and vapour Causes eye irritation Transportation UN Classification UN Hazard Class: 3; UN Pack Group: II
STORAGE
Fireproof. Separated from strong oxidants. Store in an area without drain or sewer access.

PERFLUOROBUTYLETHYLENE

ICSC: 1697

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID. Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible. The vapour is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. Chemical dangers On combustion, forms toxic and corrosive gases including hydrogen fluoride (see ICSC 0283). Reacts with strong oxidants.	Formula: C₆H₃F₉/ CF₃(CF₂)₃ CH=CH₂ Molecular mass: 246.1 Boiling point: 58°C Density: 1.4 g/l Solubility in water: none Vapour pressure, kPa at 20°C: 31.7 Relative vapour density (air = 1): 8.5 Relative density of the vapour/air-mixture at 20°C (air = 1): 3.3 Flash point: -17°C c.c.

EXPOSURE & HEALTH EFFECTS

Routes of exposure

Effects of short-term exposure
The substance is mildly irritating to the eyes.

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS
TLV: 100 ppm as TWA

ENVIRONMENT
Environmental effects from the substance have not been investigated adequately.

NOTES
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
