Lead Free Solder

[N5RXS, J C Smith]

Fred:

        Replies to your question have been informative.  I have learned a
number of things from the replies.

        Let me add my spin to the lead issue.  When soldering, some
particulates become airborne.  However, most of us spend very time soldering.
 Precautions to take when soldering include having adequate ventilation in
the work area and working from the side so the smoke or vapors are not rising
in your breathing zone.

        Studies done by communications companies indicate over exposure
occurs when lead is in a molten state or when lead cable is being removed.
The old telephone frame rooms wiring blocks were the solder type.  Air
sampling in large frame rooms where technicians were constantly running
jumper wires and soldering indicated the room atmosphere was safe.

        If you melt lead to make fishing weights you may have a problem.
Soldering electrical connections in a ventilated area should be safe.
