- Exposure to lead from soldering is NOT due to 'fumes'. The
- vapor that comes from soldering is the flux, NOT the lead or tin
- (both of which have low vapor pressure at soldering temperatures).
- Wash your hands after soldering or handling soldered objects,
- because ingestion is the important danger here.

- Tin is not toxic. Tin cans for food, tin salts in toothpaste,
- and tin in approved solder for potable water (and food handling
- machinery) have been accepted for years, and there is NO indication
- that this has been an error.
