ASSESSMENT OF SCIENCE LABORATORY MANAGEMENT AWARENESS AND SAFETY REGULATIONS KNOWLEDGE AMONG SENIOR SECONDARY SCHOOL TEACHERS
CHAPTER ONE
INTRODUCTION
1.1 Background of the study
In teaching of Science the practical work is of great importance as it develops the confidence of doing something by one’s own self. Practical work not only enhances the knowledge about a particular phenomenon but also explains the underlying ideas about it (Cooper stock, 2009). Chemistry and chemicals have an essential place in science, and safe chemical practices are the most basic and fundamental parts of laboratory experiments. Chemical safety is the prevention of the adverse effects, both short- and long-term, to humans and the environment from the production, storage, transportation, use and disposal of chemicals. (WHO 2009).There are four main ways that is routes of exposure, for chemical substances to enter the human body: Inhalation, Absorption, Ingestion (eating, swallowing), Transfer across the placenta of a pregnant woman to unborn baby
Handling chemical substances without proper precautions exposes the students, teachers and other allied staff to the risk of absorbing harmful amounts of chemicals. It is obligatory for the school administration to provide the guidelines to the respective teachers and lab attendants about the nature, properties, classification labeling, transport and storage of chemicals so that they could disseminate the information to the students before the performance of practical task for the safe use of chemicals and to minimize the risk of chemical injuries. Governments from around the world have agreed that addressing chemical threats to children’s health should be an integral component of every country’s public health and environmental agenda.
The present study has not only figured out the contemporary knowledge of science teachers about chemical safety in Public schools but also helped to know the level of practical implications of this knowledge at real laboratory environment. This study would also help researchers to develop future chemical safety programs at school levels and to analyze and explore all those ways preventing accidents with knowledge and habit of safety.
Several studies are evident about the importance of safety measures in labs. According to the survey of Gerlovich, Whitesett, Lee & Parsa, (2001) mostly the accidents and injuries in the laboratory are caused by the broken glassware and chemical exposure. The teachers who have class sizes greater than 24 students are at greater risk of being injured (Fuller, Picucci & Collins, 2001). Overcrowding in Science Classrooms and laboratories, where equipment and chemicals are used, should be a safety concern for every teacher and student (TEA & DANA Center, 2000). In Pakistan the situation is worse because of the lack of facilities, resources and proper management so this present study was conducted not only to analyze the knowledge, attitude and practices of Science teachers regarding chemical safety in laboratory, but also to point out the deficiencies present in the system, and to remove those deficiencies proper suggestions are given so that the government, school administration and other stake holders could take steps to fulfill the gap.
