Need for Code of Behaviour : A laboratory is a potentially dangerous working environment. Cuts from broken glass, chemical or thermal burns and poisoning are three examples of lab accidents that could occur. In order to avoid such lab accidents, you must follow a set of rules commonly known as personal code of behaviour. When you work as an assistant or technician in an educational lab, you have to consider the educational element of your conduct. The students around you learn from what all they see from the teachers and the laboratory staff like you; you also have a responsibility of building in students a positive attitude to safe working practice and an awareness of potential dangers. You may also appreciate that such an educational element is not necessarily associated with the code of behaviour of laboratory staff working in industry. Hence, the lab staff in educational institutions should practise personal safety code both for avoiding the accidents and for the educational value that it offers to the students learning in the lab.
