Because of the chlorine element, vinyl does not easily ignite. In fact, it can safely be described as self-extinguishing.
As vinyl burns, it releases hydrogen chloride, a gas produced from burning plastic. The emitted hydrogen chloride reacts with oxygen to form water vapour.
Besides water being a natural fire retardant, hydrogen chloride effectively removes oxygen from the surface of the vinyl fence. Oxygen is what sustains the combustion process. Hydrogen chloride, thus, effectively slows down the combustion process.
Hydrogen chloride is a toxic gas but it is released in such small quantities when vinyl burns that it does not pose health risks. It is far less dangerous than carbon monoxide, for example.
Thanks to vinyl’s fire resistance, if any fire started in the vicinity of your vinyl fence you will not have to worry about the fence adding ‘fuel’ to the fire. If anything, the fence will help to contain the fire ensuring it does not rage out of control.
