I wanted to share an accident that happend to me. Luckily I wasnt hurt as I was following basic rules when dealing with new mixtures (PPE, small amount, outside, slow). I ground some copper nitrate trihydrate and mixed it with fine MgAl powder by shaking it together in a container. The total amount of the Mix was about 5g. I then let it sit a few seconds and when I picked it up again, within half a second it burst into bright Flames, I threw it instinctively on the ground and was luckily completely unhurt. I was wearing gloves, safety glasses and long sleeves and jeans. Afterwards I found black staines on the gloves, so I know they prevented me from some burns! Even though I was reading through available MSDS I could not find spontaneous combustion as potential Hazard. I share this experience so that nobody has to make this Experience again!
