Follow normal industry safety procedures for handling and applying Teflon products. Industrial experience has clearly shown that Teflon coatings can be processed and used at elevated temperatures without hazard if adequate ventilation is used.
Oven ventilation should be available at baking temperatures of 275°C ( 525°F ) and above. Spray booth ventilation should be sufficient to capture all the overspray from powders or liquids. Before using Teflon, read the material Safety Data Sheet (MSDS) and the detailed information in the "guide" to the Safe.
