Tom Anderson ) gurgled happily, sounding much like
they were saying :

http://www.highways.gov.uk/aboutus/d...annex_2(1).pdf

"An injury for which a person is detained in hospital as an
inpatient, or any of the following injuries whether or not they are
detained in hospital; fractures, concussion, internal injuries,
crushings, burns, severe cuts and lacerations, severe general shock
requiring medical treatment and injuries causing death 30 or more
days after the accident"

So, by dint of my (unhospitalised) burns, by the definition used for
road accidents there have been serious injury accidents in my
kitchen.

I would imagine, or rather hope, that the working definition is
slightly more nuanced than the one you quote.

How "nuanced" would you like it to be, bearing in mind this has to be a
consistent definition across the entire country and across years, even
decades, for any useful information to be gained from it?

It would clearly be nonsensical to count minor burns as serious injuries.
I can't find any detailed information about how it's done, though.

Look up a little bit. That's a Highways Agency URL. What would you like as
a more authoritative source?

The next category down is Slight Injury - "An injury of a minor character
such as a sprain, bruise or cut which are not judged to be severe, or
slight shock requiring roadside attention. This definition include injuries
not requiring medical treatment"

"Severity - Of an accident; the severity of the most severely injured
casualty (fatal, serious or slight). Of a casualty: killed, seriously
injured or slightly injured"

Oh, and you don't even have to meet any of those criteria - all it needs is
for the incident report filed by the plod at the scene to report that you
might.
