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. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

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


•INHALATION Dizziness. Headache. Unconsciousness.
Ventilation.
Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
•SKIN ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
•EYES Redness. See Skin.
Safety goggles, 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


SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Ventilation. NEVER direct water jet on liquid. (Extra personal protection: chemical protection suit including self-contained breathing apparatus).
Fireproof if in building. Cool.

UN Hazard Class: 2.2
ICSC: 0837 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 COMPRESSED LIQUEFIED GAS

PHYSICAL DANGERS:
The vapour is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen.

CHEMICAL DANGERS:
On contact with hot surfaces or flames this substance decomposes forming toxic fumes including hydrogen bromide and hydrogen fluoride. Attacks plastic, rubber and coatings.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 1000 ppm; 6090 mg/m3 as TWA (ACGIH 1997).
MAK: 1000 ppm; 6200 mg/m3.
Peak limitation category: II(8). Pregnancy risk group: C.
(DFG 2007).
OSHA PEL: TWA 1000 ppm (6100 mg/m3)
NIOSH REL: TWA 1000 ppm (6100 mg/m3)
NIOSH IDLH: 40,000 ppm See: 75638


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 irritates the eyes. 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: -58°C
Melting point: -168°C
Relative density (water = 1): 1.5
Solubility in water: none
Vapour pressure, kPa at 20°C: 1434
Relative vapour density (air = 1): 5.1
Octanol/water partition coefficient as log Pow: 1.86

ENVIRONMENTAL
DATA

This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer.

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. Flugex 13B1, Freon 13B1, Halon 1301, Khladon 13B1, and Refrigerant 13B1 are trade names.
Transport Emergency Card: TEC (R)-644.
Card has been partially updated in March 2008: see Occupational Exposure Limits.
