EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation. 

Effects of short-term exposure
The substance is irritating to the respiratory tract. Inhalation of this gas may cause lung oedema. See Notes. Exposure could cause death. The effects may be delayed. Medical observation is indicated. 

Inhalation risk
A harmful concentration of this gas in the air will be reached very quickly on loss of containment. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.01 ppm as STEL 

ENVIRONMENT
 

NOTES
This substance is formed as a by-product in tetrafluoroethylene production and during thermal degradation of polytetrafluoroethylene (PTFE/Teflon(R)) at approximately 425°C.
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.
