“…For example, chemical fume hoods should be utilized when conducting toxic experiments, in order to exhaust any generated toxic aerosols to the outdoors (Berkeley Lab, 2000;& Creighton University, n.d.). However, when the hoods are either not available or used improperly, the fumes can circulate in the lab and jeopardize the air quality (Berkeley Lab, 2000;& Chien, Chang, and Lo, 2009). Additionally, unsafe handling of the substances could also increase lab emissions (Reinhardt, Ashbrook, & Leonard, 1995).…”

Working in an academic laboratory (lab) often involves handling hazardous substances (Shariff & Norazahar, 2012). These substances are dangerous due to their toxic, flammable, explosive, carcinogenic, pathogenic or radioactive properties (Furr, 2000). Therefore, it is crucial that those working in these environments do so safely. Recently, many researchers and students from various universities in the U.S. and globally have suffered severe injuries and fatalities from lab accidents. For example, in 2008 a lab fire at the University of California Los Angeles led to the death of a student(Van Noorden, 2011). Following this and other similar accidents that transpired afterwards, an international study was conducted to understand the state of safety within the wet labs of today’s universities(Van Noorden, 2013a). The findings revealed numerous safety gaps and an overall lack of a strong and positive safety culture within the labs (Benderly, 2013;and Schröder, Huang, Ellis, Gibson, & Wayne, 2016). Since the majority of the accidents and study reports were predominantly from the U.S., it is unknown if the same safety gaps and risks also exist in the wet labs of Canadian universities. Therefore, this research study examined the state of safety within the wet laboratories of a medium-sized Canadian university. This was achieved by: 1) conducting an inventory of the labs’ hazardous substances to identify their labeling and storage conditions, 2) inspecting the labs to identify potential hazards or risky conditions, and 3) surveying lab personnel to understand how safety is perceived and practiced. The results show several safety deficiencies and a negative perception on certain safety elements among the lab personnel. As in universities in the U.S. there is an overall need to enhance thecurrent culture of safety at this Canadian university.
