Is it safe to solder near Teflon tape
Soldering close to Teflon tape can cause flu-like symptoms, I have worked with Teflon pipe and tubing.
When we had to heat it, to weld it or stretch it for fittings, caution was needed and had to be careful to keep it below 500f , if higher temps were needed we did the work in a fume hood and one spring there were a lot of birds outside (mud swallows) that died because of the fumes when we were welding a bunch of segments. Birds are quite susceptible to the fumes.
If outside there is normally enough air flow but a fan above the area to push or pull the vapor away is usually enough.
Especially now I would not want flu like symptoms sad some of the guys would get careless and breathe the fumes then complain the entire next day. So use caution plenty of fresh air and you should be fine.
I usually wrap a wet towel around areas I want to prevent heat transfer to.
