Introduction
Laboratories are essential to scientific research and experimentation, but they can also be dangerous places if proper safety precautions are not taken. With the advancement of technology and the increasing demand for scientific research, laboratories have become an essential part of many industries. However, it is important to remember that laboratories can also be dangerous places if proper safety precautions are not taken.
Since 2001, the US Chemical Safety and Hazard Investigation Board (CSB) has documented a total of 120 accidents occurring in academic research laboratories. These incidents have led to an astonishing 87 evacuations, 96 serious injuries and tragically three deaths. (1)
According to the Laboratory Safety Institute, nearly a third of researchers never even consider risk before conducting laboratory work. Even more alarmingly, almost 4 in 10 personnel surveyed had been involved in an incident or injury that was not documented to the supervisor or instructor! Academic researchers displayed the least amount of risk awareness, trailed by industry and government. A study conducted between 1966 and 1984 revealed that 81% of all accidents happened in teaching labs, 13% in research labs, and 2% in fabrication rooms. Unfortunately, only 40% of those surveyed said they would put on personal protective equipment (PPE) prior to working; additionally, 25 percent had not been instructed on the precise danger that their work entailed. Despite the potentially hazardous nature of chemical reagents, chemistry journals rarely take time to highlight their associated safety protocols. A study observed 107 references to eleven dangerous substances – none of which provided any pertinent cautionary data. Even after disastrous incidents in research labs similar situations occurred again mere years later at the same institutions. (2)
These statistics highlight the importance of taking laboratory safety seriously and implementing measures to mitigate the risks. In this article, we will take a closer look at the top 10 laboratory safety hazards and provide tips on how to mitigate them, in order to keep workers safe and prevent accidents and injuries in the laboratory.
