International Chemical Safety Cards 1,1-DICHLOROPROPANE ICSC: 0723 Propylidene chloride C3H6Cl2 / CHCl2CH2CH3 Molecular mass: 113.0 ICSC #    0723 CAS #     78-99-9 RTECS # TX9450000 UN #        1992 April 07, 1997 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Highly flammable. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Powder, water spray, foam, carbon dioxide. EXPLOSION Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT GENERATION OF MISTS!  •INHALATION Dizziness. Ventilation, local exhaust, or breathing protection. Fresh air, rest.  •SKIN Redness. Pain. Protective gloves. First rinse with plenty of water, then remove contaminated clothes and rinse again.  •EYES Redness. Pain. 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. Rinse mouth. Do NOT induce vomiting. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! 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. Personal protection: filter respirator for organic gases and vapours. Separated from strong oxidants, strong bases, food and feedstuffs . Cool. Well closed. Keep in a well-ventilated room. Do not transport with food and feedstuffs. Marine pollutant.

International Chemical Safety Cards 1,1-DICHLOROPROPANE ICSC: 0723 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance decomposes on heating producing hydrogen chloride and phosgene . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. 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 irritates the eyes and the skin. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 88°C Relative density (water = 1): 1.13 Solubility in water: none Vapour pressure, kPa at 25°C: 8.7 Relative vapour density (air = 1): 3.9 Flash point: 16°C o.c. Auto-ignition temperature: 557°C Explosive limits, vol% in air: 3.4-14.5 Octanol/water partition coefficient as log Pow: 2.3 (calc.) 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.
