Loud explosion rocks Serendra

Methane gas explosion malamang na naman ito. walang signs of a grenade explosion..... But, paano nag trigger? ung mga LPG centralized meron yan safety device, a valve would immediately shut it off once a leak is detected.

IMO, still possible pag ang valve eh passing, tuloy tuloy ang bigay nang gas sa linya.

Sir, ilan psi ba bago mag trigger yan? hindi ba konting gas leak lang, mag trigger na ung valve to close it? or else walang use itong safety device na nilalagyan. prarang ganyan yan eh:

depende sa setting kung ilang pressure pag relief valve yan

sa picture idol retz yung pressure gauge sinusukat nya ba yun pressure nung linya? ano yung valve na yan sir? pressure reducing valve ba yan or relief. valve?
