leaded solder without an extractor fan

lead does not vaporize at the temps used in soldering.
lead free solder also needs fume extraction. even more so actually, because it is used at slightly higher temps. even with perfect fume extraction, leaded solder can still poison you, because you touch it and then touch your face without washing your hands.
if you are prone to allergic reactions from solder fumes avoid solder with a rosin core, use synthetic flux instead.
