Some people always think they know more than the firefighters.
The procedure for extinguishing fires is to first cover and rescue personnel and explosives, trying not to disrupt the existing combustion conditions.
Although it's burning, it's relatively stable.
Only after the rescue personnel come out, and the interior attack team ensures safety, can they start to fight the fire "violently".
If they had directly flooded the second floor with water now, without knowing the situation on the first floor, the Special Duty Squad going in to rescue the liquefied gas would have been in danger.
The water pressure going into the second floor might have caused the fire to either rush down or up.
It might even trigger intense burning and explosions.
If there's oil burning, it might even spread downwards along with the water, blocking their way out.
Everyone would face a fire inside that could change at any moment.
