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.
