PROPANE	ICSC: 0319 (November 2003)
n-Propane

CAS #: 74-98-6

UN #: 1978

EC Number: 200-827-9

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Extremely flammable. Gas/air mixtures are explosive.	NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state. Use non-sparking handtools.	Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, carbon dioxide. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Drowsiness. Unconsciousness.	Use closed system or ventilation.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin	ON CONTACT WITH LIQUID: FROSTBITE.	Cold-insulating gloves. Protective clothing.	ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .
Eyes	ON CONTACT WITH LIQUID: FROSTBITE.	Wear face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Remove all ignition sources. Ventilation. NEVER direct water jet on liquid.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 2.1
STORAGE
Fireproof. Cool.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance ODOURLESS COLOURLESS COMPRESSED LIQUEFIED GAS. Physical dangers The gas is heavier than air and may travel along the ground; distant ignition possible. The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. As a result of flow, agitation, etc., electrostatic charges can be generated. Chemical dangers	Formula: C₃H₈ / CH₃CH₂CH₃ Molecular mass: 44.1 Boiling point: -42°C Melting point: -189.7°C Relative density (water = 1): 0.5 Solubility in water, g/100ml at 20°C: 0.007 Vapour pressure, kPa at 20°C: 840 Relative vapour density (air = 1): 1.6 Flash point: -104°C Auto-ignition temperature: 450°C Explosive limits, vol% in air: 2.1-9.5 Octanol/water partition coefficient as log Pow: 2.36

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system.	Inhalation risk On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation.

Effects of short-term exposure
Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system.

Inhalation risk
On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS
MAK: 1800 mg/m³, 1000 ppm; peak limitation category: II(4); pregnancy risk group: D

ENVIRONMENT

NOTES
Check oxygen content before entering area. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
