TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

In case of fire: cool cylinder by spraying with water but avoid contact of the substance with water. Combat fire from a sheltered position.
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Burning sensation. Tightness in the chest. Cough. Laboured breathing. Shortness of breath. Symptoms may be delayed (see Notes).
Closed system and ventilation.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
•SKIN Redness. Pain. ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves.
Remove contaminated clothes. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Redness. Pain. Blurred vision.
Face shield, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION

PHYSICAL STATE; APPEARANCE:
COLOURLESS COMPRESSED LIQUEFIED GAS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground.

CHEMICAL DANGERS:
The substance decomposes on heating above 300°C, on contact with water and moisture , producing toxic and corrosive gases ( carbon monoxide and hydrogen chloride ). Reacts with aluminium, isopropyl alcohol.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 ppm as TWA; (ACGIH 2002).
EU OEL: 0.02 ppm, 0.08 mg/m3, as TWA; 0.1 ppm, 0.4 mg/m3, as STEL; (EU 2002).
OSHA PEL: TWA 0.1 ppm (0.4 mg/m3)
NIOSH REL: TWA 0.1 ppm (0.4 mg/m3) C 0.2 ppm (0.8 mg/m3) 15-minute
NIOSH IDLH: 2 ppm See: 75445


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

INHALATION RISK:
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract . Inhalation of this gas may cause lung oedema (see Notes). The effects may be delayed. Exposure at high levels may result in death. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 8°C
Melting point: -118°C
Relative density (water = 1): 1.4
Solubility in water: reaction
Vapour pressure, kPa at 20°C: 161.6
Relative vapour density (air = 1): 3.4

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 is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder). Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
