BS EN 15004-4 is the fourth part in a multi-series that specifies requirements for gaseous fire-extinguishing systems, with respect to the HFC 125 extinguishant. It includes details of physical properties, specification, usage, and safety aspects.
BS EN 15004-4 is applicable for systems operating at nominal pressures of 25 bar and 42 bar, super pressurized with nitrogen. This does not preclude the use of other systems.
BS EN 15004-4 on gas extinguishing systems is relevant to:
A gas extinguishing system is a fire extinguishing system that extinguishes the fire with the help of a gaseous extinguishing agent through oxygen displacement.
BS EN 15004-4 covers guidelines on system design, including requirements on fill density, super pressurization, extinguishant quantity as well as environmental properties.
BS EN 15004-4 is helpful as the adoption of these requirements and specifications can aid in protecting safety personnel from hazards arising from:
BS EN 15004-4 is beneficial as the properties, design and performance requirements and guidelines enables you to establish efficient firefighting systems during hazardous situations, that are devoid of product failures.
