wooden ventilation shafts left, one of which,
via a connection in the ceiling of the office
floor above the shop water & sanitation/gar-
dening section, passes into the attic.^9 On his
way to the incident site Olsson has also called
for reinforcements by part time firefighters in
Allmänsta and Närby.^10
‘I want a sector on Drottninggatan, one
at the hotel, one at the department store
sports section and one on Storgatan. Anders-
son, you take command of the Drottningga-
tan sector. That’s where we’ll work primarily
with the aim of preventing the fire spreading
up through the building. Johansson will be
the sector commander at Storgatan.’^11
101, 102, 103, 104 and 106 are now
at the incident site. Part time firefighters
121 and 125 are on their way. A total of
eight firefighters and four commanders are
operative at the incident site. A further four
firefighters and one commander are on their
way to the incident site.^12 Part time firefigh-
ters from Närby, 131 and 137, four firefigh-
ters and one commander^13 are on their way
to Allmänsta fire station.
(^9) Familiarity with the object is often a
prerequisite for forming a realistic plan.
Knowledge of the parameters that in dif-
ferent ways steer the course of events is
also beneficial. In the case of a burning
building, personnel should have varying
degrees of knowledge of the fire safety
aspects of structural engineering.
(^10) It is important to, at an early stage, be
able to pick up signals indicating that a
situation may develop into something
exceptional. The provision of resources and
sustainability are important aspects and
must be dealt with during the course of an
operation, at the same time as emergency
preparedness must also be taken into
account. This is where gaining a balance
between the ongoing operation, assistance
need, risk situation in the municipality
and emergency preparedness comes into
the picture.
(^11) It can often be advantageous to divide a
large incident site up into sectors, to the pur-
pose of clarifying tasks, roles and responsi-
bility. These can be formed on the basis of
tasks or geography. The important thing is
to be clear in the allocation of authority to
different commanders. This is where decision
domains come into the picture. A decision
domain is defined in terms of certain areas of
authority in time and space. They can be for-
med in different ways depending on, among
other things, the situation.
