Read the actual directive, and drill down. Basically, it's up to each
nation to decide the categorization. And if you dive further down into
that, the reporting requirements may or may not give you any but the most
general geographical information, and very little to assess what the
potential hazard might be. One example I looked at, for instance stated
that certain chemicals were present onsite, but for a microchip
manufacturer that could be a single bottle on the shelf - on the other
hand, any bulk chemical processing facility might have tens of railroad
tanker cars lined up. As far as I could tell, there may not actually be any
on site, they are simply 'registered' to store it for use. Another factor
is that businesses startup and shutdown, so like all bureaucratic
procedural information, what is the plan for continuous maintenance?

information of public interest.

Other nefarious parties are also interested. So. the addresses in some
cases are only the administrative 'home office', not the exact locations,
which are to be given to the local law enforcement, fire, and other
emergency responders - which makes sense because otherwise it would provide
a ready target list for thieves and terrorists ( there is an entire federal
agency division dedicated to this in the U.S.
https://www.dhs.gov/cisa/chemical-security ).

Use the tagging ( categorization ) scheme the regulatory agency themselves
uses to classify these sites.

If you by chance mean historical sites, that presents another set of
issues. I live a couple blocks from
https://cumulis.epa.gov/supercpad/cursites/csitinfo.cfm?id=1000614  and it
is profoundly uninteresting because it has been stabilized for decades.
Much different than
https://cumulis.epa.gov/supercpad/cursites/csitinfo.cfm?id=1001114 which
has huge leaking tanks of radioactive stew that could kill a exposed human
within seconds.

> But I barely find some site tagged in practice, ...

Probably because they ran into the issues above. My inclination is that
this is a good case where OSM should be combined as a layer in Leaflet with
an available map
