Hi HappygoLucky,

1. As the houses are all air conditioned the explosion due to excessive temperatures do not arise, if that is of any concern.

on 1-
if this is the case then gas explosions do not seem to be contained particularly in high rise buildings which would definitely need to be air conditioned given the weather extremes inherent in the gulf region.

neither are they contained in apartments of smaller buildings.

therefore how did you arrive at the connection between air conditioned units and explosions being compressed due to the presence of air conditioned units?
