Ang mga question ko dito sa incident na ito on property management perspective are:

1. why is is the leak detector of the lpg system did not activate, IMHO it should have 2, one in the pipe chase and one near the LPG outlet of the unit.

2. considering the scale of the blast, why is it the smoke detector did not detect any changes in the air inside the unit.
- ung iba wag pilosopo na smoke detector nga eh.
- most of the detectors even during old ages can detect changes in the composition of air mixture which will trigger the alarm. which should have also avoided this catastrophic event.
- IMHO - something is definitely wrong in the administration of the building.

3. To build up that amount of LPG inside the unit it is a standar operating procedure that guards should conduct roving inspection, again, why it was not detected by roving guard.

Related to the triangle above, i believe the emergency cut-off valve of the LPG system triggers that is why there is no fire. However, the amount of the LPG is adequate enough to make that blast.

By the way, i am not from Ayala or any of its subsidiary but based on the pictures of the apartment, i think the prefab walls were constructed properly. and IMHO again this can be prevented by the maintenance/property management people.
