Team,
Just after a little help and advice on high rise building contruction. i have heard but i am not sure as this is not my area of expertise that there are certain safety features built into highrise buildings. Most notably stairwells. Are stairwells positive pressure? Meaning if you can get to one smoke will not impede that area and will provide a fresh air source for trapped casualties trying to escape?
I guess the design trade off would be you are potetially positively ventilating the fire so if doors are left open or the fire breaches that stair column, then you risk making things worse. I have heard that positive pressure stairwells do exist but i haven't been able to confirm this.
A follow on question is, what do you advise the public regarding fire safety education? If trapped in a building do you advise heading to a window or heading to the fire stairwell. i understand in smaller buildings, you have external fire escapes but in high rise the only option is internal stairwell.
Would appreciate any help on this one team.
