A flashback can be caused by a variety of conditions such as sustained backfire, incorrect hose purging or simply the wrong gas pressure. Most areattributable to operator errors. When a flashback occurs the flame front and pressure wave retreat into theblowpipe and hose at a very high speed. This can cause detonation within thesystem. It is essential that the regulator and more particularly the cylinder areprotected from the effect of a flashback. The well proven 36ec conforms to the requirements of BS EN 730-1.
