Question: When testing to find things that detect explosives have you ever been hurt?

Hi @568sped46. I have not had any incident so far…fingers crossed! In chemistry, the concentration you use in your chemicals is very important. I try to keep the concentrations very low to minimise the risk. Also, some very explosive chemicals like TNT (probably you’ve seen this three letters in some movies) are quite stable. They become explosive after you trigger them (by heating, pressure,…)
