Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable chemicals may be stored nearby to electrified instrumentation). Therefore, knowledge regarding electrical safety and what to do in case of emergency is essential for the laboratory personnel. Precautions can be employed when working in the laboratory to avoid electric shock and electrical fire or explosion.
