5. Secondary risks
– During firefighting, large quantities of water contaminated by extinguishing
additives, by soot etc. may occur which has to drain from the affected rooms.
In an adverse case, it might flow into lower floors which may also be used as
storage areas, and it might not be able to drain off from a basement. Addi-
tional objects might be affected by this.
– Flue gas contains a large quantity of particles (soot) which is distributed
throughout the building via the ventilation system, transport route as well as
the smallest openings and gaps and then settles on objects. Cleaning a con-
taminated object is (if at all) only possible with a lot of effort and usually only
to an unsatisfactory extent.
– Fire residues, dampness, temperature and climatic conditions can lead to a
micro-climate which promotes within a short time the growth of mould. This
contamination is an acute danger to objects as well as for the employees in-
volved.
– After such an event, an evacuation may be necessary. If preparations have
not been made, additional risks can occur in which wrong priorities are made
or front-ranking objects are not accessible/cannot be found.
Technical systems must be set up in such a way that contamination of collections
is avoided in the event of an incident. Sensible room set-up as well as impervious
partitions for all passages must be implemented (e.g. fire damper).
After such an event, it must be ensured immediately that outside influences
(weather, climate, temperature etc.) are controlled again very quickly.
Secondary risks can partly be minimized within the scope of the emergency plan.
6. Biological pests
– Leaky building shells are a gateway for pests.
– Uncontrolled movement of objects can lead to infestation of pests such as
moths, silver fish, museum beetles, golden spider beetles, larder beetles etc.
– Dust, dirt and rubbish in badly cleaned storage areas are an ideal medium for
the development and reproduction of introduced pests.
– Unsuitable climatic conditions (e.g. damp outside walls, cool/damp basement)
can lead to unwanted growth of mould.

Introducing Integrated Pest Management (IPM) helps to prevent infestation by
pests or to recognize it early. The following aspects are included:
– Rooms and facilities which are easy to clean as a front-ranking planning goal
– Scrupulous compliance with cleanliness in the storage areas and infrastructure
rooms
– Checking all incoming and outgoing endangered objects for pest infestation as
well as treating contaminated objects
– Systematic pest monitoring in all rooms with objects and regular checks of the
stock in storage rooms
– Systematic containment of an infestation
– Quarantine for infested objects
