“…Four out of five of the participants (79.2%) had never received formal training in emergency response procedures. Lack of chemical laboratory safety training has been cited as a reason for science teachers' suboptimal safety awareness (Kandel et al, 2017). This aspect was confirmed when participants in this study requested blank questionnaires to keep in their laboratories as a safety reference.…”

“…In addition to the indispensability of hands-on chemical experiments for learners in their learning of science, many studies also emphasise the importance of developing chemical safety awareness for both teachers and students (Eguna et al, 2011;Kandel et al, 2017). Sigmann (2018) points out that some laboratory activities in high school can be too risky when teachers have not been trained to conduct chemical experiments with groups of adolescents, or when laboratories lack proper emergency equipment or where there are no purpose-built laboratories to conduct the experiments.…”

“…There is wide consensus on the difference in approach to chemical safety awareness between developed countries and developing countries. While laboratory chemical safety awareness is prioritised in developed countries, it is often neglected in poorer countries (Eguna et al, 2011;Kandel, 2017). For Schenk et al, (2018), some of the challenges on CLS safety practices and awareness stem from large classes and teachers' inadequate understanding of adolescent behavioural patterns.…”

There is a scarcity of studies that focus on how South African high school physical sciences teachers are grappling with chemical laboratory safety (CLS). This is despite the fact that the Curriculum and Assessment Policy Statements in the South African school system increased emphasis on laboratory activities in the physical sciences. Department of Basic Education authorities have increased the supply of resources, including chemicals, in schools to ensure the successful implementation of the practical component. This quantitative study investigates physical sciences teachers' levels of CLS awareness through a conceptual framework developed by the United States National Research Council aimed at promoting chemical laboratory safety in developing countries. A laboratory safety survey questionnaire for teachers was administered to 72 physical sciences teachers from 72 schools in one province. The questionnaire consisted of 14 statements with a four-point Likert scale. Teacher CLS awareness was found to be generally suboptimal, especially concerning awareness of safe chemical storage and waste disposal, and emergency laboratory safety procedures. Results from the computed Pearson chi-squared tests for statistical significance suggest that teachers from better-resourced schools and those who had majored in chemistry had greater awareness than those from less wellresourced schools and those who had not majored in chemistry. Authorities could consider safety awareness training to accompany the provision of resources to schools and target those teachers who may not have majored in chemistry. Such training could include, but not be limited to, online laboratory awareness courses that exploit the use of multiple virtual tools.

“…In Nepal, a study concluded that there was improper disposal of chemical waste and the lack of monitoring the laboratory safety [16]. Likewise, Li [as cited [14]] stated that the liquid waste from all levels of school laboratories in Taiwan was around 1,691,100 liters in the year 2000 consisting of harmful wastes such as heavy metal liquid, organic liquid, acid and alkaline liquid waste.…”

Teaching and learning of chemistry involves scientific tests and experiments that take place in laboratories. It involves using hazardous chemicals and equipment posing risks and health hazards to the users. Hence, the users should be thoroughly versed with laboratory safety practices. Therefore, an attempt to understand the safety practices in chemistry laboratories in schools have been examined in this study.The data were collected administering a mixed method. Both descriptive and inferential statistical tools were used to analyse quantitative data while qualitative data were analysed thematically. Congruency of the eight predetermined themes was established by triangulating the quantitative and qualitative data using Statistical Package for Social Sciences version 21.The results indicated that the schools had good safety practices with adequate laboratory facilities and safety skills. The schools were also aware of emergency planning and chemical storage and labeling. However, schools lacked properly trained safety practitioners. It was also observed that chemicals and waste materials were disposed of without treatment. Further, it was also observed that there were shortages of safety gloves and goggles fume hood and pipette fillers.The study recommends school administrators, chemistry teachers, and laboratory assistants to procure unavailable items required for the safe conduct of chemistry laboratory activities. The study further recommends the Ministry of Education (MoE) to provide training to chemistry teachers and laboratory assistants on the safe handling of hazardous materials and on first aid techniques to address accidents.

“…In chemistry laboratories, instructors and students work with chemical substances and devices and are exposed to various risks (Kandel et al, 2017). For this reason, there is a requirement for a number of trainings and arrangements in order to minimize the harm by intervening risks that may occur in a conscious way.…”

In general chemistry laboratories of universities, faculty members and students work with chemicals and devices and they are exposed to various risks. For this reason, it is of great importance whether teacher candidates are who are the teachers of future are adequately equipped in terms of laboratory safety or not. This study was conducted on teacher candidates who participated in General Chemistry Laboratory practices in Science Teacher Education program and their opinions and knowledge levels about laboratory safety were investigated. In the study, teacher candidates were informed about the necessary precautions while working in a general chemistry laboratory in 4 courses. Then, in order to increase the awareness and responsibility of the students via the information that taught in courses, the General Chemistry Laboratory Safety questionnaire form given in the appendix was applied. The questionnaire form developed for laboratory safety was applied to 81 teacher candidates. According to the results obtained from the study, it has been found out that teacher candidates mostly find the general chemistry laboratory safety important and understand the importance of information about safety. SPSS 13.0 was used to analyze the consequences of the survey.
