Flame Arrester. A Flame Arrester also spelled arrestor is a device which allows gas to pass through it but stops a flame in order to prevent a larger fire or explosion. There is an enormous variety of situations in which flame arresters are applied.
Another type of spark arrestor can be either functional or decorative. It is generally a self-supporting screen or shield placed a short distance from an open fireplace flame. It serves the same purpose as an exterior screen, keeping stray burning embers from escaping from the fireplace and possibly starting a fire.
