Staircases often become choked with smoke. You have minutes, perhaps, before you are are risk for hypoxia and smoke inhalation.
Opening fire doors can undermine the safety of others if they don't get closed properly (or if you allow smoke or fire to start pouring into a floor.)
That said, it's been clearly demonstrated that developers are unwilling (or unable) to pay for proper fire safety, so all bets may be off.
- bigbubba 6y agoI would not enter a stairwell that was filled with smoke. Smoke rises, so if there is smoke in the stairwell below me, it's probably also in the stairwell on my floor as well, though there may be a small window where I get mislead. Nevertheless, in America these stairwells are designed specifically to be used for evacuations, and in my city the official advice is to GTFO as quickly as you can using a stairwell the moment you hear the (building wide) alarm or if you see smoke. So this is certainly what I would do.
- mypalmike 6y agoHaving been a participant in the attempted evacuation of a 15 story building during multiple fire drills, I'm not looking forward to ever having to evacuate for real. After 2 hours under ideal conditions, the stairwells were still clogged with people, and nobody above around the 10th floor got out.
