Gas lighters use butane gas as fuel. When using them, you should pay attention to the following points:
(1) There should always be gas in the lighter. Check the gas storage capacity of the lighter. Just shake the lighter and hear the sound of liquid (butane is a liquefied gas) hitting it, which means there is still gas in the lighter.
(2) When lighting and adjusting the flame, do not aim at the face or get too close to the face to avoid the flame spraying out and causing an accident.
(3) When filling the gas, do not do it near fire, and do not heat it with fire to prevent explosion.
(4) After use, the fire cover should be lowered in time to extend the use time of the gas. The outlet valve should be kept clean at ordinary times, and the dirt on the lamp head should be cleaned with a brush frequently to avoid the flame skewing phenomenon.
