NO open flames, NO sparks, and NO smoking. Powder, alcohol-resistant foam, water spray, carbon dioxide EXPLOSION Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE  •INHALATION Ventilation. Fresh air, rest.  •SKIN Rinse skin with plenty of water or shower.  •EYES Redness. 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 STORAGE PACKAGING & LABELLING Personal protection: self-contained breathing apparatus. Remove all ignition sources. Consult an expert! Cover the spilled material with foam blanket. Do NOT wash away into sewer. Fireproof. Separated from strong oxidants. Store in an area without drain or sewer access. UN Hazard Class: 3 UN Packing Group: II Signal: Danger Flame Highly flammable liquid and vapour Causes eye irritation SEE IMPORTANT INFORMATION ON BACK ICSC: 1697 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 PERFLUOROBUTYLETHYLENE ICSC: 1697 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible and may accumulate in lowered spaces causing a deficiency of oxygen. CHEMICAL DANGERS: On combustion, forms toxic and corrosive gases including hydrogen fluoride . Reacts with strong oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV: 100 ppm as TWA (ACGIH 2007). MAK not established. ROUTES OF EXPOSURE: INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is mildly irritating to the eyes . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES 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. ENVIRONMENTAL DATA N O T E S Environmental effects from the substance have not been investigated adequately. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
