Yes of course, but in order to use the samples in my lab I still need such sheets as a guarantee, that the powder samples can be used. So if you have any idea where I could find such (maybe some international or official standards sheets) I would be very gratefull.I am a retired degreed chemical engineer with experience in ordinance manufacture, amines and all sorts of stuff. I also reload. I have to say these MSDS sheets are intended to have no practical value other than to meet regulatory requirrements. I suppose you could use them for a sleep aid. My best advice to preppers is, "The sky is not going to fall and if the SHTF it will all be a matter of luck.
