International Chemical Safety Cards FURAN ICSC: 1257 FURAN Furfuran Divinylene oxide Oxacyclopentadiene C4H4O Molecular mass: 68.1 CAS # 110-00-9 RTECS # LT8524000 ICSC # 1257 UN # 2389 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Extremely flammable. 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. Use non-sparking handtools. In case of fire: keep drums, etc., cool by spraying with water.   EXPOSURE PREVENT GENERATION OF MISTS! INHALATION Cough. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention. SKIN Redness. Remove contaminated clothes. Rinse skin with plenty of water or shower. EYES Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Do not eat, drink, or smoke during work. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: self-contained breathing apparatus). Fireproof. Separated from strong oxidants, acids. Cool. Well closed. Store only if stabilized. Airtight.

International Chemical Safety Cards FURAN ICSC: 1257 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: CLEAR COLOURLESS LIQUID, TURNING BROWN UPON STANDING , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance can form explosive peroxides upon contact with air. Reacts violently with oxidants and acids causing fire and explosion hazard. Fire hazard upon exposure to heat or flame. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour and by inhalation of its aerosol, and through the skin. INHALATION RISK: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The vapour irritates the respiratory tract. Inhalation of the vapour may cause lung oedema (see Notes). EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 31.3°C Melting point: -85.6°C Relative density (water = 1): 0.94 Solubility in water: poo Relative vapour density (air = 1): 2.3 Flash point: -35°C Explosive limits, vol% in air: 2.3-14.3 Octanol/water partition coefficient as log Pow: 1.34

ENVIRONMENTAL DATA
N O T E S
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Check for peroxides prior to distillation; eliminate if found.
