[Tagging] fire extinguisher class

[Florian LAINEZ]

Hi everyone, thanks for your feedback, I can see that the topic is much
more complicated than I expected.

Let's sum up our proposals:

   1. Describe the classes fire_extinguisher_class=A
   2. Describe the local classes fire_extinguisher_class:uk=8A 55B 75F
   3. Describe the combustible fire_extinguisher_class=ordinary_combustibles
   4. Describe the kind of combustible fire_extinguisher:electrical=yes or
   fire_extinguisher=electrical
   5. Describe the type of powder fire_extinguisher_class=water
   6. Describe the written label fire_extinguisher:label=black

What I think of them:

   1. Describe the classes: they are not standard internationally and I
   think we should avoid them
   2. Describe the local classes: not suitable worldwide
   3. Describe the combustible: it requires to understand the kind of fire
   that is suitable for an extinguisher : It can be subjective as the brakets
   denote in the table here
   https://en.wikipedia.org/wiki/Fire_extinguisher#United_Kingdom
   Also we would potentially have multiple keys e.g.
   fire_extinguisher_class=ordinary_combustibles;flammable
   liquid;electricity
   4. Describe the kind of combustible: again it requires to understand the
   kind of fire that is suitable for an extinguisher
   5. Describe the type of powder: could be a good solution but the bad
   think is that we would potentially have multiple keys e.g.
   fire_extinguisher_class=water;foam;dry_powder
   6. Describe the written label: difficult to standardise

It seems that none of these solutions is perfect, which one do you think
would be the best as an international standard?

My choice would be "5. Describe the type of powder" with the following keys:

   - water
   - foam
   - dry_powder
   - co2
   - wet_chemical
   - class_D
   - halon

Again, it's the only tag that describes the object itself without
interpretation and that can be standardised. Of course it would require a
conversion table, but either way I guess we'll have to go through this
process.
Have a good day
