[QUOTE=brainmafia_310;2154490]rephrase ko idol, gas leak detector perform as the function similar to smoke detectors that trace chemical composition in the air which is one of the requirement ng BFP per Fire Code fo the Philippines it is a must in all centralized LPG systems. kaya nga nagtataka ako bakit umabot sa burst yung LPG inside the condo which should have been detected by both LPG Leak Detector and even the Smoke detector which is sensitive enough (for both photo and ionization type) to detect changes in the minute particles of the air (even some cooking witthout the smoke per se) eh nagaalarm sya.[/QUOTE]
