Hazards in the chemical laboratory

Abstract

With the growth of academic institutions, the number of labs handling hazardous chemicals has increased. Although the chemicals used in academic institutions are well-known, the dosage, usage, and management of these chemicals pose significant threat to researchers at all levels. As a step towards incident prevention, a laboratory incident database was developed to record incidents at universities and secondary schools. The data consisted of 128 entries occurring during the years 2012–2015. Incidents were classified by institution type, hazard type, consequences, substance type, body parts injured and direct causes. Of 128 incidents, 65% of the incidents were taking place in universities. Chemical spills were observed to be the most recurrent hazard type contributing to 45% of the incidents following by explosions (23%) and fires (21%). The consequence which most frequently occurred in incidents was personal injury and hazmat response contributing to 22% each. It was observed that in 41% of the incidents, the body parts injured in the incident was not known or reported. Of the total 128 incidents, about 50 incidents occurred due to improper storage and handling.
