Whether it is safe to cook in a PTFE-coated pan?

You might wonder if it's safe to cook in a PTFE-coated pan.The answer is yes, if you're careful.PTFE is stable at moderate temperatures,like you'd use to cook eggs or fish,but above 500 degrees Fahrenheit,it starts to degrade,and heating it further releases fumes that can make you feel sick.An empty pan can reach 500 degrees fast over high heat,but most kitchens are ventilated well enough to dissipate the fumes.
