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 (OELs):
TLV: 1000 ppm; 6090 mg/m3 as TWA (ACGIH 1997).
MAK: 1000 ppm; 6100 mg/m3; IV (1995)
OSHA PEL: TWA 1000 ppm (6100 mg/m3)
NIOSH REL: TWA 1000 ppm (6100 mg/m3)
NIOSH IDLH: 40,000 ppm
|
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.

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.
