Tie dye  and safety measures

Reactive dyes  are not very dangerous. An occasional small spill on the hands is no big deal (unlike the situation with more dangerous types of dyes such as naphthols dyes and sulfer dyes . It is important to avoid drinking the dye, eating with unwashed hands after spilling dye on them, or breathing the dye powder. (It is okay to eat with dye-stained hands if the hands have been washed very thoroughly with soap and water.)
