Arrestors allow gas and vapor to flow through but prevent backflow of flames to avoid larger fires and explosions. In the event of a flame making it to the arrestor, the flame cell element absorbs heat to prevent the flame from propagating further upstream.

The geometry, size length of piping and piping systems are important to consider when selecting a flame

arrestor. It is possible that the level of turbulence generated by combinations of these factors may render

a flame arrestor incapable of quenching a flame front. Studies have noted that a correlation of the

performance of a flame arrestor and piping size is not always possible. It may be necessary to have tests 

performed for the particular size of flame arrestor proposed for use.
