What will be an ideal response?
A backfire occurs when a flame goes out with a loud snap or pop. A backfire may be caused by (1) touching the tip against the workpiece, (2) overheating the tip, (3) operating the torch when the flame settings are too low, (4) a loose tip, (5) damaged seats, or (6) dirt in the tip. The problem that caused the backfire must be corrected before relighting the torch. A backfire may cause a flashback.
