What are the three safety rules you must always follow when using a Bunsen burner?

When using a Bunsen burner, always ensure that your hair and loose clothing are secured and away from the flame to prevent fire hazards. Always use the burner on a stable, non-flammable surface and keep flammable materials at a safe distance. Finally, never leave the burner unattended while it is lit, and always ensure that the gas is turned off when you are finished using it.
