How a fire code writes exits

A fire code turns a room's use and size into required exits, widths, and hardware.

From the opening

A fire code writes exits by setting the means of egress: how many ways out, how wide they are, how far a person may travel to reach one, and how doors and stairs must behave. The rules translate an expected crowd and a kind of hazard into a path that is supposed to remain usable during a fire. The opening covers occupant load sizes the exits, travel distance limits the path, and doors must open for a crowd.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
