Not sure if this is a catch question, and bearing in mind that I am not a sprinkler specialist, but is it not still as simple as it always was, namely, for High Hazard Risks,  four categories of high piled storage, referred to as Categories l, ll,lll and lV respectively, and four categories of process hazards, which off the top of my head are referred to as type 1, 2 3 and 4. Or am I missing something about the question?

Gerneral Risk - that implies you are talking about the categories Ordinary Hazards I - IV

other than their names, what do you need to know? The BS is advised for anything other than a simple question or the answers may take up pages of this board up!

Anthony, He asked about stored good, implying that he is talking about the 4 Cats of High Hazard (Stoorage).

Thanks guys,

Let me put it another way;

Stored goods in a sprinkler protected building generally fall into 4 categories. What type of goods fit into each of the risk categories.

 i'll go for OH category 1-4 as BS5306-2 gives a table of goods stored.
As usual the 'risk' and 'hazard' are getting mixed up somewhere.
