is assumed that a full, large, medium and a small fire leads to 100 %, 75 %,
30 % and 5 % of a full scale fire respectively.
In practice, a full scale fire is defined as a fire where more than three fire
hoses were needed for extinguishing the fire, a full scale fire is considered as
a complete burnout. A large fire is in this context defined as a fire that involves
the use of two or three fire hoses for fire extinguishing and is assumed
to typically involve the majority of a house, an apartment, or at least
part of an industrial complex. A medium size fire is in this context defined
as a fire involving the use of only 1 fire hose for fire-fighting and will typically
involve a part of a single room in an apartment or house. And a small
size fire is in this context defined as a fire that was extinguished before the
arrival of the fire service, extinguished by small tools or a chimney fire.
The total number of registered fires is known for the years 1989-2010. For the
years 2007-2010 the total number of registered building fires is known with a
very high degree of detail.
Table 7.14 shows the occurrence of all types of fires (registered for 1989-
2010) and the occurrence of building fires (2007-2010) registered at DEMA.
The 1980-1988 data for all fires are estimated to be the average of 1989-2010
data. In 2007-2010 the average percentage of building fires, in relation to all
fires, was 60 %. The total numbers of building fires 1980-2006 are calculated
using this percentage. The full time series is presented in Annex 2D Table
2D-7.

The total number of building fires is quite higher this year than last year.
This is due to the addition of additional building fires and container fires in
this year’s inventory.
The building fires that occurred in the years 2007-2010 are subcategorised
into six building types; detached houses, undetached houses, apartment
buildings, industrial buildings, additional buildings and container fires.
Table 7.15 states the registered activity data for building fires for the years
2007-2010, divided in both size and building type. The calculated averages
