On 21 July 17, after setting up the experiment in Fumehood A, the researcher noted that the hotplate with stirrer was malfunction. Thus he moved the experiment set-up to Fumehood B that has another hotplate with stirrer. At Fumehood B, he mixed the chemicals (vanadium oxide and hydrogen peroxide) in a 500 ml reagent bottle and placed it on a hotplate with stirrer (without heating). After setting the stirrer at 300 rpm, he then closed the bottle with the cap, and lowered the sash. 2-3 minutes later, he returned to Fumehood B and noted that the temperature of the hotplate with stirrer was at 88°C. When he tried to off the heating function, the reagent bottle containing the chemicals shattered. Fragmented glass pieces flew out from the opening between the sash and the bottom edge of Fumehood B. The researcher suffered several cuts and was immediately taken to the hospital for treatment. 2.
