N O T E S
|
|
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.
Card has been partly updated in April 2005. See section Notes.
