There are a number of safety rules to keep in mind when using a Bunsen burner. The most common in a class room are:

  1. Check the rubber tubing for any cracks or tears to be sure no gas escapes.
  2. Check the gas valve screw on the bottom to be sure it does not fall out.
  3. Be sure the air valve is just slightly opened to allow enough oxygen to ignite the gas but not too much that it extinguishes the flame.
  4. Light the match prior to turning on the gas so that unlit gas doesn't escape into the air.
  5. If the flame is extinguished during the experiment immediately shut the gas valve off.
