Remember to always wear closed-toed shoes in the lab. Consider wearing a lab coat to cover any loose clothing.
To reinforce safety habits, avoid touching the barrel even if the burner isn’t in use.
The gas main outlet is a threaded nozzle that tapers to a point. Look for a label on the top of its handle, such as “GAS” or “VAC,” or ask your lab instructor for help.
Whenever you put the burner away, you should make sure the needle gas valve is closed. That way, it’ll be set up for the next person to use. You want the needle valve closed when you turn on the gas supply so you’ll have complete control over how much gas you feed the burner when you ignite it.
After you’ve made sure the burner’s needle gas valve is closed, you can try turning on the gas supply outlet again. If you still hear a hissing noise, consult with your instructor to try and find the problem.
Use a flint striker or lighter with a long nozzle. Don’t use matches to light a Bunsen burner.
If you’ve never used a striker before, practice making sparks until you’re comfortable using it.
Adjust the air flow slowly to avoid blowing out your flame.
Remember to close the air ports to create a cooler flame when you’re not heating something, and never leave the lit burner unattended. [16] X Research source
Before you leave the lab, double check the gas main to ensure you’ve turned off the gas.
