With gas, you are always careful. It is important to ensure environmentally and fire-safe conditions. One such condition is good ventilation. The pressure propane exerts on a tank or gas cylinder depends on the temperature. The higher the temperature of the liquid, the higher the pressure of the gas. And the lower the temperature, the lower the pressure. This means that propane bottles should be protected from heat sources. For this reason, always put your gas bottle(s) in a well-ventilated, open place outdoors. Do not cover the bottle, even with a camouflage net. And make sure that any vegetation around the bottle does not obstruct ventilation.
