Bit of a drift but when I was working in quarries we used ammonium nitrate mixed with diesel as a cheap, fairly powerful explosive. A couple of sticks of gelignite at the bottom of a bore hole to give a clean shear at the base then amfo, as we called it, to give the push needed to blow a few metres of granite clear of the quarry face. I never heard the slightest concern voiced about the safety of handing ammonium nitrate and even when mixed with diesel it needed a blast from the gelignite to set it off.
A handful sprinkled on the lawn was an economical source of nitrate fertiliser!
