Americans seem to take a lot of pride in their fire brigades - their fire engines are still shiny and polished with more traditional signage and the fire fighters still wear helmets with their traditional shape.

In the United Kingdom they wear more simple uniforms and the engines are just a box shape with no bells any more - seems a shame.

Usually it's UK the has more ceremony in these kind of things.

artisanal ladders

x2. This seems like a case where there probably exists better options but the cost and friction of switching is too high. As long as the money's still coming there's no reason to look for alternatives though, especially when looking for alternatives would involve doing battle with a union over the jobs the alternatives would eliminate. Does SF really have that many more overhead power lines than other cities to warra…

Fiberglass is a terrible choice for these ladders. Most places use Aluminum or steel but that has conductivity issues with the amount of overhead powerlines in SF. They can be coated to reduce conductivity but that has other issues.

3. May chip and crack with impact forces. 4. May suddenly crack and fail when overloaded. 5. Can burn when exposed to flame.

If you get a chance to visit a Smokejumper base, I highly recommend it. One of the things you learn is that everyone on the team is required to make all of their own equipment by hand. So all of these highly trained, ex-military guys spend days on end doing nothing but sewing clothes and packing parachutes. The reasons described: - Cheaper than contracting out everything - They have a better idea of the exact specifi…

It makes sense for a job where 95% of the time is spent waiting for an emergency to react to.

All you're describing sounds way more expensive than a couple carpenters...simply being able to fix a ladder than toss it is a huge saving

Its the little details: -- For example, a 3" Fiberglass Ibeam 10 feet long is ~$200, and only rated to 140 degrees. I can't readily find a more comparable product.

-- your aluminum ladder with high temp rubber, also needs to be electrically insulated; so now you have to toss the whole ladder if the shell is breached in any little way, and probably needs to be re-certified yearly.

- a lesson from outside of the software industry. Not really, just a forgotten one. Fred Brooks described his ideal development team in The Mythical Man Month and it included a toolmaker.

That was also written before there were many commercially available tools. (Still a great book!) Perhaps tool specialist is more important today?

> There's a city-specific reason why San Francisco has stuck with wood rather than swap over to metals, and the answer lies in looking up. The high-voltage cables and wires that guide the city's (oft-maligned) public transport system Muni, and trolley cars crisscross above nearly every street, mean that ladders made of conductive elements are generally just too dangerous to use.

I wonder how it's done in European cities with their trams (the ones which don't use APS).
