Check your venting, esp if your machines are sharing a vent to the outside.
Perhaps you have a fan that is no longer working, or a vent that someone
accidentally shut.

Also, in a past life, we had a similar problem during the onset of the
hotter weather-  line operators were setting up powerful fans to cool off,
without realizing the consequences of having a fan blowing directly into a
wave solder machine or reflow oven.  If they've done the same thing at your
place, you've probably got a few other problems as well.

Dear technetters,

Recently we have some problems with our breething air inside the building.
Some of us think its due to the outgassing of the just soldered pcb's,
others think it is the flux.
Main problem occurs in front of the soldering machines and the reflow oven.
There is now a discussion going on about the safeness of fluxes and
soldering (pastes).
My question is if someone had the same problems and what did they do to
reduce these problems?
