PERFLUOROISOBUTYLENE ICSC: 1216
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS GAS.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.01 ppm; (Ceiling value); (ACGIH 2004).
MAK not established.
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 respiratory tract. Inhalation of this gas may cause lung oedema (see Notes). Exposure may result in death. The effects may be delayed. Medical observation is indicated.

PHYSICAL PROPERTIES
Boiling point: 7C
Density: 1.6 g/l
ENVIRONMENTAL DATA

NOTES
This substance is formed as a by-product in tetrafluoroethylene production and during thermal degradation of polytetrafluoroethylene (PTFE/Teflon(R)) at approximately 425C. The occupational exposure limit value should not be exceeded during any part of the working exposure. 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 are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Card has been partly updated in April 2005. See section Notes.
