The teacher's first responsibility is to familiarize students with basic laboratory rules of safety. Food and drink consumption should never be allowed in the presence of chemicals and biological agents. Mixing chemicals for playful experiment could result in unknown serious consequences. Even common household products, such as bleach and ammonia, could become hazardous when accidentally mixed. Therefore, students should be knowledgeable of general laboratory rules.
Teachers should familiarize students with the proper use of safety equipment. Goggles, gloves and protective clothing provide the first line of defense against accidental chemical spills and potential splashing of reagents. The second line of defense is safety showers and eyewash located in easily accessible areas. Protective clothing and wash devices provide better protection against corrosive chemicals used in laboratories once students are taught how to use them.
A good policy is for students to review each laboratory procedure prior to beginning it in class. Notes, outlines and flowcharts help students to understand the design of the method and potential risks involved. With early preparedness, teachers are capable of reviewing the method and discussing the hazards each step could contain before students begin conducting the lab. Preparedness and understanding of the task at hand prevent possible injury.
A laboratory safety program provides more benefits when students are involved in the program. It goes beyond establishing a set of rules for students to follow. Each student could become responsible for maintaining part of the safety program. For example, a group of students could take turns testing eyewash and safety showers to ensure proper function. Another group could present information concerning hazardous chemicals used during the next experiment. Students will gain from trusted responsibilities of maintaining safety in the classroom laboratory.
