1,1-DICHLOROPROPANE	ICSC: 0723 (July 1997)
Propylidene chloride

CAS #: 78-99-9

UN #: 1992

EC Number: 201-165-3

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Highly flammable. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive.	NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting.	Use water spray, foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT GENERATION OF MISTS!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Dizziness.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest.
Skin	Redness. Pain.	Protective gloves.	First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.
Eyes	Redness. Pain.	Wear safety spectacles.	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.	Rinse mouth. Do NOT induce vomiting.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Evacuate danger area! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 3; UN Subsidiary Risks: 6.1; UN Pack Group: II
STORAGE
Separated from strong oxidants, strong bases and food and feedstuffs. Cool. Well closed. Keep in a well-ventilated room.
PACKAGING
Do not transport with food and feedstuffs. Marine pollutant.

PHYSICAL & CHEMICAL INFORMATION
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 Decomposes on heating. This produces hydrogen chloride and phosgene.	Formula: C₃H₆Cl₂ / CHCl₂CH₂CH₃ Molecular mass: 113.0 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 (calculated)
