Ryan; I acquired the MSDS data sheets on two solders, the organic and the no clean. In both cases, the datasheets stated that the fumes are known to cause occasional respiratory and eye irritation, which I have observed in our shop. It also mentioned that unless the solder is ingested, which is unlikey, lead poisoning is not a risk. Keep in mind, though, that the new pastes used in SMT can easily be spread on the hands and elsewhere. I tend to be more careful with the paste for that reason.
