What a disaster I've had with a recent chemical spill. I'll start from the beginning.. My darkroom is next to my office that I work from home a few days a week. The last two days working from home I feel uncomfortable with my breathing. I chalk it up to hot weather and poor venting in my office. I then go into my darkroom to get something and find selenium toner all over my table and floor, a good 4 sq. meters fairly saturated, AND a massive stench. Obviously some of the fumes were getting into my home office and I had no idea that's why I was not feeling well for a few days, sigh. So today I spent about 3 hours cleaning it all up. I used a special fumes mask to keep from dropping dead in the process. I am not sure yet if my darkroom will always have a selenium smell now or it will eventually wear off. So far I think I got most of it. Is there anything I should be worried about now? Could the fumes for a few days deposited harmful substance on anything in the room? I still have no idea how the jug tipped over several days ago. Thanks
