TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible. Heating will cause rise in pressure with risk of bursting.

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

In case of fire: keep cylinder cool by spraying with water.
EXPOSURE


•INHALATION Dizziness. Dullness. Headache. Suffocation.
Ventilation.
Fresh air, rest. Artificial respiration may be needed. Seek medical attention if you feel unwell
•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: FROSBITE.
Safety goggles or face shield .
Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
•INGESTION


SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Personal protection: self-contained breathing apparatus. Ventilation.
Fireproof if in building. Keep in a well-ventilated room.

UN Hazard Class: 2.2
Signal: Warning
Cylinder
Contains gas under pressure; may explode if heated
ICSC: 0609 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

PHYSICAL STATE; APPEARANCE:
COLOURLESS, ODOURLESS, COMPRESSED LIQUEFIED GAS .

PHYSICAL DANGERS:
The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.

CHEMICAL DANGERS:


OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:


INHALATION RISK:
On loss of containment this gas can cause suffocation by lowering the oxygen content of the air in confined areas.

EFFECTS OF SHORT-TERM EXPOSURE:
Suffocation. The liquid may cause frostbite.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: -108.1°C
Melting point: -111.8°C
Solubility in water, g/100 ml at 20°C: 0.6
(very poor)
Relative vapour density (air = 1): 4.5
Octanol/water partition coefficient as log Pow: 1.4

ENVIRONMENTAL
DATA


N O T E S

High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Transport Emergency Card: TEC (R)-20G2A
Other UN number 2591, Xenon, refrigerated liquid, hazard class 2.2.
