Don,
What framebuilders should be concerned about are the florides (sp?)
that are released from the brazing flux. Do not breath the stuff. Do
not braze in a draft, but it is advisable to have adaquate exhausted
ventilation. I still use Easy-flow 45 silver brazing allow because
from my experience it is still the most ideal and superior silver
allow for brazing frames. Many seem to be afraid of the cadmimium. So
be afraid. I am not. To release the Cad one must overheat the silver.
Since Cad is a heavy metal it will seek ground level. You do not want
your pet dog hanging around the shop where you are brazing; and avoid
braking while lying on the floor also. ;-) Care must be taken to wash
your hands after handeling brazing rod, which one should do no matter
what type of brazing you do. For total safety from brazing gasses I
suggest a full Haz/Mat suit with fresh air resperator, full armour
shit, and a chastity belt. Personally, I'm just careful with my
materials, know what to be careful of, and then become one with my
process and materials. Fear of the stuff is far worse than the
material in many cases. Just my opinion. In painting it is even more
important.
So Don, I do wear protection while brazing; just not the type one
would expect. But I've never spread Cadmimum to anyone else.
Brian Baylis La Mesa, CA Brazing condoms available, just ask at the deug counter.
I read somewhere that brazing releases toxic emissions, not just from the torch combustion, but from the metals and flux being heated.
1. Is this true?
2. If yes to 1, then do framebuilders protect themselves from the toxic emissions?
3. If yes to 2, how do they protect themselves?
