Lab reagent accident case 1: Getting burned by stepping on potassium chlorate that had fallen to the ground. 2. Fires broke out during the process of using an organic matter spoon to weigh diacetyl peroxide. 3. During the sealed storage of a concentrated hydrogen peroxide solution, the plug may fly out, causing hydrogen peroxide to spill and catch fire (it is better to use a breathable plug). 4. When refining dibutyl peroxide with silica gel and filtering it through a Büchner funnel, an explosion occurred (due to the precipitation of peroxide on the filter bed). 5. When producing oxygen using hydrogen peroxide, the addition of manganese dioxide causes a rapid reaction that leads to the rupture of the flask. 6. When throwing items contaminated with used gasoline into the fire to burn them, unexpected intense flames are generated, causing burns. 7. When the flask is washed with propane and then placed in a drying oven for drying, the remaining propane vaporizes and causes an explosion. The door of the drying oven was blown off and flew far away. Feel free to add more!
