Firefighters are terrible at evaluating risk:
- Requiring all passengers in cars to wear helmets: would save 350 lives a year in California
- Requiring small apartment buildings to have a second staircase: saves zero lives a year in California

The dead end corridor lengths and occupancy limits in currently deemed safe double stair buildings is greater. Ruins their entire “study” with a simple diagram.

Wanted to highlight this point on travel distances & occupant loads in single stair building proposals.
This example has the same travel distance as what is already deemed safe for dead end corridors. Often w/ higher actual occupancy
Pushback against these is purely vibes-based x.com/trevoracorn/st…
God I love this diagram, despite it being an illustration of utter absurdity
Agreed. It’s also been helpful with more reasonable firefighters.
Once you see the 6 units in the dead end vs 4 in a single stair visually it makes the whole redundant stair/attack stair argument look kind of foolish. If the single stair is compromised, they’re coming in from
You can’t get out of the double loaded corridor building if that stairway is blocked either. Except in that case it’s more people that are trapped and need rescued via window or balcony.
