Welcome to our school lab.I'm very happy to introduce our school's lab to you.
Well.before doing any experiments,there are a few laboratory safety rules that we must remember.
First off,the most important thing is conduct ourself in a responsible manner at all times in the laboratory.As you see ,the students should follow teachers'instructions carefully. If we do not understand a direction or part of a procedure, we need to ask our teacher before proceeding with the activity.
Also,students should not touch any equipment, instruments, or other materials in the laboratory area until we are instructed to do so.
When leaving the labortory, students need to put back all the instruments back into the cupboard and keep the laboratory clean and tidily.
Lastly,we also need to close all the windows and lock the doors of the lab.
After my inrtroduction,i hope you understand a bit about the safety rules of the lab in our school.
