Our lives are ﬁlled with hazards created by electrical power supply, lasers, chemicals, and a
diversity of equipment used in laboratories and classrooms. While studying science and engin-
eering and performing experiments, students will learn to identify hazards and to protect
themselves. Students will also learn to take care of their health and safety while working in
laboratories. A safer and healthier learning and working environment should be created so that
students have the opportunity to live safely and more healthily.
