When conducting a flame test with a Bunsen burner, students should follow these safety precautions to prevent injuries:
-
Wear Appropriate Personal Protective Equipment (PPE): All students should wear safety goggles to protect their eyes from potential splashes or sparks. Lab coats or aprons should also be worn to protect their skin and clothing from chemicals and heat.
-
Use Proper Lighting Techniques: Students should ensure that the Bunsen burner is lit safely using a striker or a long lighter, keeping their hands and face away from the flame. They should also ensure that the gas supply is turned off before lighting the burner to avoid gas buildup.
-
Maintain a Safe Workspace: Ensure that the area around the Bunsen burner is clear of flammable materials, such as paper, cloth, or chemicals. Students should also keep their hair tied back and avoid loose clothing that could accidentally catch fire.
Additionally, having a fire extinguisher and knowing how to use it, along with knowing the location of the nearest sink or safety shower, can further enhance safety during experiments with open flames.
