POLYTETRAFLUOROETHYLENE

SECTION 2: Hazards identification

EMERGENCY OVERVIEW This material when properly handled according to good working and hygienic practices is not dangerous to human health and the environment. Toxic gases may be released at temperatures of 400 oC (752 oF) and above. For short and long term exposure effects see Section 11 Toxicological data. Eye Effects: No effects requiring first aid are expected during normal use. Eye contact with thermal decomposition products causes redness, irritation, burns. Skin Effects: No effects requiring first aid are expected during normal use. Skin contact with thermal decomposition products causes redness, irritation, burns. Skin contact with molten product can cause burns. Ingestion/Oral Effects: No effects requiring first aid are expected during normal use. Inhalation Effects: No effects requiring first aid are expected during normal use. Slight inhalation of thermal decomposition products or smoking contaminated tobacco can cause ’fluorine polymer fever’ after 2 - 6 hours (allergenic alveolaritis with influenza- like symptoms: high temperature, shivering, chest pains, cough, increased pulse). Treatment is generally not necessary, symptoms disappear after 48 hours. The result of massive inhalation of thermal decomposition products (in temperatures > 450 °C) is that after a time without symptoms (4 - 24 hours), pulmonary oedema starts with the danger of suffocation.

Medical Conditions Generally Aggravated by Exposure

None anticipated during normal use. Fumes produced at elevated temperatures may aggravate pre-existing eye, skin, and respiratory conditions.
