This British Standard is an adoption of an ISO standard. You can access the ISO version here.
BS EN 15004 is a European Standard on gaseous extinguishing media and systems that are a part of fixed firefighting systems. The main objective of the BS EN 15004 series is to ensure gas extinguishing systems’ performance plays a positive role during a fire emergency.
BS EN 15004-9 is the ninth part of the multi-series specifies requirements for gaseous fire-extinguishing systems, with respect to the IG-55 extinguishant. It includes details of physical properties, specification, usage, and safety aspects
BS EN 15004-9 is applicable for systems operating at nominal pressures of 150 bar at 15 °C, 200 bar at 15 °C, and 300 bar at 15 °C. This does not preclude the use of other systems, although design data for other pressures are not available at this time.
BS EN 15004-9 on gas extinguishing systems for IG-55 extinguishant 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 15004-9 provides guidelines on system design, including physical properties of extinguishing systems, use of IG-55 systems, the safety of personnel, extinguishant quantity, and environmental properties.
BS EN 15004-9 is helpful as the adoption of these requirements and specifications can aid in protecting safety personnel from hazards arising from:
Compliance with BS EN 15004-9 is beneficial as the properties, system design, performance requirements, and environmental guidelines enable you to establish efficient firefighting systems during hazardous situations, that are devoid of product failures, and contribute to a successful fire response.
