Actually, I am sorry I got into this discussion. I don't have this problem so I don't have to deal with it, was just offering some suggestions. Did not intend to give bad advice.
Don't be, It’s a good discussion, not every one realizes the legality, or the risk. I know many beeks getting Phosphine and sulfur from different sources and using them, even though they have no clue what they are doing or the dangers. None of them have sniffers or even know the exposure limits.
.5 ppm for sulfur, and 3ppm for Phosphine require respirators. 15ppm for Phosphine and 5ppm for sulfur reguire full supplemental oxygen on them.
Yes that’s one half of 1 ppm, according to the documents I have.
