The letters seem like specialist knowledge that few people will be aware of. Phil (trigpoint ) But the letter codes are exactly what's printed in huge letters right on the extinguisher. That makes them easily verifiable, and instantly localized since you'd tag what's on the ground in your country. Class A
In the UK, the class is not printed huge letters. They main thing they are labelled with is the contents of the extinguisher, with a coloured stripe. ie red for water, blue for powder, black for CO2.
Some fire extinguishers also give more detailed specifications for the class etc. But this is usually not very obvious, you would have to look closely to spot it. Note a fire extinguisher can be suitable for several classes of fire, and it may give a rating for each. eg the specification might say: 8A 55B 75F
I think it is worth tagging both the materials in the extinguisher, and the class/rating where it is known. And probably worth using different tags for the class in each country.
eg something like this: fire_extinguisher:material=water fire_extinguisher:class:uk=8A 55B 75F _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
