The safety, health and environment (S.H.E.) management consists of many elements that are integrated based on modern scientific modes of operation to achieve a patterned and dynamic management system. Focusing on prevention and continuous improvement, the S.H.E. management possesses self-discipline, self-improvement, and self-motivation mechanism. It has been followed in experimental teachings in Experiemental Center for Chemical Technology at Tianjin University. Safety teaching is perfomed both in classroom instruction and in practical operation. In classroom lectures, students could have concentrated classes before any experimental assignments in the laboratories. The instructor gives possible aspects on experimental safety and correct ways to handle. At the same time, students can have a deep understanding of laboratory safety by analyzing typical chemical laboratory safety accidents in the world. Another task of classroom lectures is to understand the icon and meaning of safety marks" in the laboratories, the characteristics of chemicals involved in the following experiments, and the use of protective equipment including protective clothing, goggles, gloves, and even gas masks. Furthermore, the following aspects are strcitly considered in practical operation. Environment Safety The experimental area is divided into two parts, i.e. "Non-test Area" and "Test Area". Electrical Safety Each experimental device is equipped with an overload protector and a leakage protector separately to prevent electrical overload or electric shocks. Chemical Safety Detailed records are required for purchase, storage and use of chemicals. The waste chemicals are recycled or treated regularly. The exhaust gas is emitted via the ventilation pipe for treatment. Operation Safety The instructor should explain the operation points and precautions before any experiment, and monitor the students' operation to give correct instructions on spot. The experimental teaching for over 20 years has proved that keeping vigilant on S.H.E. management can guarantee the successful completion of chemical engineering experiments with safety.
