This seems like there are varying definitions in different countries, 
but all aim at basically the same thing - potential hazards to the 
environment. How about this scheme?

hazard_class = comah:XYZ
hazard_class = seveso:XYZ

It establishes a common top-level tag and country specific / system 
specific values. This is analogous to e.g. zone:traffic and 
zone:maxspeed used on roads. The 'XYZ' values depend on the 
classification given by the respective scheme.

We could think about adding the country code to the key (like 
hazard_class:US, hazard_class=UK) to separate countries from each other, 
but this doesn't seem necessary.

I wouldn't recommend to add the scheme to the key (as in 
hazard_class:soveso), because this tends to create quite messy tags that 
are difficult to use.
