Concerns / watch-outs

Wok cooking requires very high heat — exactly the temperature range where PTFE coatings degrade fastest
PTFE fumes at wok temperatures (500°F+) can be dangerous to birds and irritating to humans

The worst application for a PTFE pan. Woks are meant for screaming-hot heat, which accelerates coating breakdown significantly. Carbon steel is the correct low-tox alternative here.
