Fire hydrant locations are confidential

Strolling around the village I saw a man working in the street. The van had a Humberside Fire and Rescue logo and the man was fixing a hydrant sign to a wall. A quick chat established that he was checking they were present and replacing imperial hydrant signs with metric ones. I asked him if any data about the location of the hydrants is available. He said he would ask someone to call me about it.

A little later I got a call from HF&R. I asked if the location of fire hydrants was available and was told in no uncertain terms that they were not. I explained about OpenStreetMap and the caller told me that OSM had no reason to add hydrants, adding that their locations are confidential. When I said that as the data is not available I would just continue to add the ones I see as part of surveys he repeated that their locations are confidential and added that they belong to Yorkshire Water, the local water company. He asked why I wanted to put hydrants into OSM and I told him that such details make a richer map.

The locations of hydrants are hardly confidential, there is a yellow sign showing where each one is. I was a bit surprised by the HF&R man's indignant reaction. It does seem that the notion of opening up data has not reached into that public body at all.

I have only added a few hydrants experimentally and stopped because it didn't seem worth the effort. I may add a few more, but not, it seems, based on HF&R data, and only under the cover of darkness.

Haha. "Confidential". I hope you laughed at him.

I'd say they have to deal with a lot of vandalism, and are afraid that a "freely available list of hydrants" would make things worse. Cue http://www.kilkennycoco.ie/eng/RSSLatestNewsAndAnnouncements/Stolen_Ringbouy_a_Stolen_Life.26012.shortcut.html which explains that vandalism costs the not-so-big town of Kilkenny 300€ a week (!).

Maybe the way to convince authorities is to explain that making the info public wont make vandalism any worse, and might actually improve things (my making the community feel like they own the props, rather than degradations being someone else's problem)

That's hilarious. But you know, if you've never even heard of the concept of licensing, or open source or whatever, I can kind of see how you might think it could be "confidential".

The bit that's harder to understand is why on earth anyone would think that *fire hydrant* locations should be "confidential". They're public safety devices after all.

Submit an FoI request.

I decided to remain polite, who knows when our paths may cross again.

Chris Hill said...

The message of Open data is a hard one for some people ti grasp.

Chris Hill said...

FoI responses are copyright, so I would still need permissionto use any data in a reply. Somehow I don't think permission would be forthcoming. :-)

Andy Mabbett said...

Once the FoI response is received (or published - do it via "What Do They Know"), you have demonstrated that the locations are nor confidential, and can lobby your local councillors who sit on your fire authority to press for use of an open licence. Or use the list as a source to check against when doing on-the-ground surveys.

In any case, what confidential items are tagged with bright yellow signage?"

Calling these locations confidential when each has a big yellow sign would be like, ooh, putting up a street sign to a secret nuclear bunker... wait, what?

A similar situation happened with UK post boxes - the post office wouldn't give out the exact location so someone built a web app where people could locate post boxes more precisely:

The dracos site was an interesting way to display the information, though it might actually break the copyright of Royal Mail as FoI replies are still copyright. It also caused a few misguided people to just add postboxes to OSM willy-nilly when actually the data was so poor it certainly needed surveys to check it. I did some postbox surveying myself.

Section 58 of the Terrorism Act 2000 apparently gives a punishment of up to 10 years for collection of information likely to be useful to terrorists.

Although I think keeping the locations of something in public streets silly, I could imagine the government using that law to stop you. Quite scary I think.

I put on events and at an event safety advisory group meeting was told by the fire and rescue officer there that i could not cover with market stalls or anything else the fire hydrants so how can one do that if they won't tell you where they are.

I operate a comprehensive real estate portal covering Nova Scotia, Canada, property. We extensive data, including municipal data. We don't have fire hydrants but I recently asked the Halifax Water Commission (who own the hydrants) for location data. To my surprise, they cited 'security concerns' for 'critical infrastructure' as the reason they wouldn't provide the data. I asked which policy or legislation prohibits the disclosure but they couldn't refer to any. Stranger than fiction but true in 2013.

My insurance company wants to know the distance of my dwelling from a fire hydrant...if I was moving to a new location that information would be helpful prior to the move.
