Flame and spark arrestors

Research has shown that pressure-vacuum vents are just as effective as flame arrestors for storage tanks against internal ignitions. 

Spark arrestors are provided on the exhaust of source or fire where a hot particulate might be released (i.e., internal combustion engines, chimneys, incinerator stacks, etc ). The spark arrestor consist of a fine metal screen to prevent the particulate matter from being released from the exhaust mechanism.
