SIST EN 15276-1:2019
EN 15276-1:2019 (E)
Introduction
It has been assumed in the preparation of this document that the execution of its provisions is entrusted
to appropriately qualified and experienced people in the specification, design, installation, testing,
approval, inspection, operation and maintenance of systems and equipment, for whose guidance it has
been prepared, and who can be expected to exercise a duty of care to avoid unnecessary release of
extinguishant.
Firefighting systems covered in this document are designed to provide a supply of fixed condensed
aerosol extinguishing medium to extinguish fire.
The requirements of this document are made in the light of the best technical data known at the time of
writing but, since a wide field is covered, it has been impracticable to consider every possible factor or
circumstance that might affect implementation of the requirements.
It is important that the fire protection of a building or plant be considered as a whole. Aerosol
extinguishant systems form only a part, though an important part, of the available facilities, but it
should not be assumed that their adoption necessarily removes the need to consider supplementary
measures, such as the provision of portable fire extinguishers or other mobile appliances for first aid or
emergency use, or to deal with special hazards.
Aerosol extinguishants have been recognized as effective media for the extinction of Class A fires (solid
surface burning fires) and Class B and Class C fires according to EN 2 but it should not be forgotten, in
the planning of comprehensive schemes, that there can be hazards for which these mediums are not
suitable, or that in certain circumstances or situations there can be dangers in their use requiring
special precautions.
Advice on these matters can be obtained from the appropriate manufacturer of the aerosol generators
or the extinguishing system. Information can also be sought from the appropriate fire authority, the
health and safety authorities and insurers. In addition, reference should be made as necessary to other
standards and statutory regulations.
It is essential that fire-fighting equipment be carefully maintained to ensure instant readiness when
required. Routine maintenance is liable to be overlooked or given insufficient attention by the owner of
the system. It is, however, neglected at peril to the lives of occupants of the premises and at the risk of
crippling financial loss. The importance of maintenance cannot be too highly emphasized.
Condensed aerosol can contain traces of toxic substances like those produced by a fire, and will obscure
vision like smoke from fire. This standard requires, as a precaution, that the room is evacuated and
sealed off whenever a generator is activated — much like recommended response to fires. Precautions
include evacuation of the proximity area, criteria for re-entering and other safeguards.
