Here lies a pretty cool article about a pretty cool practice demonstrating how the SFFD maintains their own equipment, to their own specifications (rather than an approximation thereof), and for less money than simply farming it out to a vendor. There might even be an applicable (to HN) lesson here on the value of employing an in-house toolmaker, whatever your profession may be.
And then there's this lot here in the comments that is completely in arms against it because le Hackernews is obviously an expert Fire Brigade, or just has an allergic reaction to civilian government agencies maintaining their own equipment versus joining the throwaway consumerist cult the rest of world has acquiesced to.
