1. Cover it with a lamp cap. If it is a glass lamp holder, it needs to be covered again after it is covered, and alcohol vapor is released to let air in, so as to avoid negative pressure in the cover after cooling, so that the cover cannot be opened; If it is a plastic lamp holder, it is not necessary to cover it twice, because the sealing performance of the plastic lamp holder is poor. Never blow it out with your mouth.
2. When adding alcohol, be sure to turn off the fire first, and then add it after the furnace core cools down; Check whether the alcohol storage in the alcohol box is between 20% and 80%. If the alcohol is too full, it will easily overflow and catch fire after being ignited. If the alcohol content is too small, the alcohol box is easily filled with alcohol vapor, which may explode once it is ignited after being mixed with air.
It should be noted that when using disposable alcohol stoves, it is necessary to ensure that there are no flammable materials or flammable liquids around to avoid fire accidents. At the same time, after the alcohol furnace is treated, the used lamp holders and alcohol boxes should be properly disposed to avoid environmental pollution.
