Staying safe in the lab means knowing what dangers your students may find, and how to avoid them.
1. Fire
 Make sure all flammable materials in the lab are properly closed, and be sure to train students to the use of burners  to prevent sudden flares.
2. Heat Burns
Holding hot items without the proper tools can produce serious burns. Teacher shoud teach students how to properly use tongs, water baths, and other equipment, and stress the importance of never touching hot surfaces with a bare hand.
3. Chemical Burns
Protective gloves are essential when someone is holding chemicals. Teachers should instruct students on the importance of treating chemicals with caution, and advise them to use only approved containers for transferring and containing  irritating chemicals.
4. Cuts and Scrapes
When using sharp tools for dissection, students should receive instruction in how to safely handle the equipement. In addition, when disposing of sharp items, like broken glass, needles, or razor blades used for cutting lab materials, be sure that students know to carefully wrap these items before carrying to the trash.
5. Contamination
It's important that all students in the lab follow careful handwashing procedures. Before and after interacting with any foreign substances, students should wash their hands, and also protect their clothing and skin with lab gloves, and/or glasses. Leaving the lab with bacteria, tissue, or other potentially harmful substances on their skin or clothes can result in contamination of desks or lunch tables, causing illness.
6. Inhalation
Accidentally inhaling gases in a poorly ventilated space can cause headaches and nausea. Teachers should teach students the proper procedures for opening windows, using ventilation fans, and using equipment to measure the amount of gas emission in a room to ensure safety.
7. Spills and Breaks
Spilling liquids and dropping glass beakers is typically the result of not following procedures and rules. Teacher should give the directions for moving through each step of the lab to avoid any hurried movements, and let students know about the potential dangers that can come from spilling chemicals and breaking glass in the lab.
