recent studies have stated that the pans offgas from manufacturing for weeks after you’ve bought them, no heating needed, so no, that’s not correct. and it was known that they offgas at only 325ºF years ago. https://www.ewg.org/research/canaries-kitchen

so no, teflon pans are bad no matter how you use them, they’re bad for the environment, they’re bad for your health, they’re bad for animals, they’re bad for babies that haven’t been born yet.
