“…Potential fire incidences must be recognised and assessed so that controls can be implemented to reduce risks (Sigmann, 2018). Handling practices and procedures should be developed for potential laboratory hazards (Hill, 2019), such as in the appropriate use of fume cupboards (NRC, 2010).…”

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.

“…The potential hazards and risks are often recorded in laboratory activities to have caused chemical explosions, radiation, as well as physical and biological exposure [1,3,8]. This led to the focus of most previous studies concerning work accidents in universities on laboratory activities [3][4][5][9][10][11]. Some other examples of hazards include fire [3,12,13], construction works [1], and natural disaster [14,15].…”

The accidents recorded during university construction projects usually affect the safety performance of the institution. This indicates it is important to recognize the hazards and construction risks at the design stage in order to have an optimal safety plan. Moreover, the university area has several organizations involved in the implementation of Occupational Health and Safety Management Systems (OHSMS). Therefore, there is a need to develop the OHSMS information system to accommodate the role of the parties involved and to disseminate information and communication more effectively. This study was conducted to develop a WBS and BIM-based safety plan for the OHSMS information systems to improve the safety performance using the case study method. The result showed that the WBS is the basic constituent of the safety plan integrated with the BIM to visualize the project in real terms in order to ensure easier identification of hazards and risks. The process involved building data security information in BIM to develop web-based information systems and the BIM-based OHSMS information system developed is expected to improve safety performance in the university area.

“…Most work accidents occur when the hazards of a working environment are not properly managed, either because they are not perceived as risks before the work starts, or because they are not fully understood. Therefore, appropriate training should be given to new employees to recognise and understand the hazards [1]. It has been reported that young workers have a higher non-fatal accident rate than older workers [2,3].…”

The purpose of occupational health and safety studies is to protect employees from work accidents and occupational diseases and to ensure that they work in a healthy environment. Most of the work accidents happen as a result of wrong storage, transportation and use of chemicals. In order to protect employees from chemical hazards and eliminate their possible risks, a risk assessment should first be carried out. Based on the results of the risk assessment, if not done before, bottles that contain hazardous chemicals must be classified and labelled according to their risk levels. The labels of bottles that contain chemical liquids must be checked and if the labels are worn or unreadable, they must be renewed. After these have been done, hazardous chemical liquids must be classified, stored and transported according to these labels. In this study, a non-contact, liquid measurement system based on microwave data is proposed to detect hazardous liquids. In order to select the most suitable algorithm for use in this measurement system, 3 different classification algorithms have been used and the performance analysis of the algorithms has made. In the study, 3 different classification processes have been applied according to the chemical properties of the liquids. It has been observed that Random Tree algorithm has achieved the best performance while Rep Tree algorithm has done the worst performance. Using this system, hazardous chemical liquids can be detected without opening the cover of the bottles that contain the liquids. Therefore, it can be used to quickly label hazardous liquids for their safe storage and transportation.
