NYC: Big fire (4th alarm now) across a church and several multi-unit residential buildings at 12th St and 27th Ave in Astoria.
-
This is a BIG fire, and still burning. They just called in two additional trucks. But it's starting to wind down. They just declared "probably will hold", which is the step before "under control". Over three hours so far.

Anyway, it's a very interesting and complex real-time systems optimization problem, with lives at stake. And it was solved with 19th century technology, with the basic principles unchanged to this day.

@mattblaze Very interesting! I never knew how the x-Alarm system actually worked.

@mattblaze how long until a tech bro comes and says: "wow, that system is outdated. Look at my shiny AI... We feed it with the fire location and it will tell the dispatcher who to send..."

@mattblaze I appreciate learning about this from a guy named Blaze

@carstenfranke
And then gets told where to shove it. Disaster response communities are pretty careful about this kind of thing and have a certain amount of autonomy because of the whole people dying thing.

Some terminology: There are two basic kinds of firefighting vehicles: "Engines", which carry hoses and pump water, and "trucks", which have telescoping ladders. Each is crewed by 4 or 5 firefighters. Engines are chiefly responsible for putting out the fire, while trucks are chiefly responsible for rescuing people (and getting access to high floors). In NYC, a "battalion" has a chief that supervises (generally) two engines and one truck
Each additional alarm adds roughly 4 engines and 2 trucks.
@mattblaze Fascinating thread, thank you. I had no idea this existed, although now you explain it, it makes perfect sense.

@mattblaze oh man, I hope not too many people are injured and that nobody dies.

Several firefighters injured after a collapse in the church. Now a fifth alarm (the maximum pre-determined response).
The FDNY "alarm" system addresses an interesting and difficult optimization problem in dispatching additional firefighters to large incidents. And it's largely unchanged from the 19th century. It's really quite clever.
Some background:
I loved reading this thank you. Fascinating mechanical system still effective: Another I would share with you is the dabbawalla food delivery system in Mumbai. They collect cooked food from a workers home and deliver it to them at their desk at lunchtime. After lunch they collect the containers and return them to homes. All done with numbers and markings on the containers. …/2

2/ They became necessary because the Mumbai transit system is so crowded commuters cannot carry very much. The system was designed to deliver to small offices and honeycombed streets. But deals with large offices and has been expanded to collect from restaurants. Computerisation would only work at the node points, mainly the stations, but it has been tried and slows down the sorting dramatically and led to mistakes.

@mattblaze the Battalion Chief is the person who shows up in a general purpose vehicle (typically a small SUV these days) painted like the engines/trucks. This person coordinates the firefighting staff for larger incidents.
If you watch the order of vehicles heading to a fire, you can get a sense of the type and severity without knowing anything else about it.
