Table 1 Types and causes of accidents.
From: A new approach for explosion accident prevention in chemical research laboratories at universities
Case Study 1 (Texas Tech University) | Case Study 2 (University of Hawaii) | |
|---|---|---|
Type of accident | Explosion of chemical substances | Explosion of inflammable mixed gas |
Cause of accident | The student used more than the prescribed usage limit of 100 mg of nickel hydrazine perchlorate (NHP); therefore, the powder exploded while the NHP was being stirred with a pestle | An electrostatic discharge occurred when a researcher used a pressure gauge, which ignited the hydrogen/oxygen gas mixture in the gas storage tank in which the explosive gas mixture was stored at high pressure, resulting in an explosion |
