TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Extremely flammable.
NO open flames, NO sparks, and NO smoking.
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 .
EXPLOSION Gas/air mixtures are explosive.
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.
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE


•INHALATION Drowsiness. Unconsciousness.
Closed system and 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.
Face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION


SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Personal protection: self-contained breathing apparatus. Evacuate danger area! Consult an expert! Remove all ignition sources. Ventilation. NEVER direct water jet on liquid.
Fireproof. Cool.

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, and may accumulate in low ceiling spaces causing deficiency of oxygen. As a result of flow, agitation, etc., electrostatic charges can be generated.

CHEMICAL DANGERS:


OCCUPATIONAL EXPOSURE LIMITS:
TLV: (Aliphatic hydrocarbon gases) 1000 ppm as TWA; (ACGIH 2005).
MAK: 1000 ppm, 1800 mg/m3;
Peak limitation category: II(4); Pregnancy risk group: D;
(DFG 2006).
OSHA PEL: TWA 1000 ppm (1800 mg/m3)
NIOSH REL: TWA 1000 ppm (1800 mg/m3)
NIOSH IDLH: 2100 ppm 10%LEL See: 74986


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
On loss of containment this liquid evaporates very quickly displacing the air and causing a serious risk of suffocation when in confined areas.

EFFECTS OF SHORT-TERM EXPOSURE:
Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: -42°C
Melting point: -189.7°C
Relative density (water = 1): 0.5
Solubility in water, g/100 ml 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

ENVIRONMENTAL
DATA


N O T E S

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.
