Overview
SIST EN 15004-7:2018 is a European Standard developed by CEN that specifies requirements for fixed gaseous fire-extinguishing systems using the IG-01 extinguishant. IG-01, based on Argon, is designed for applications where automatic gas extinguishing is necessary to protect people, property, and assets. This part of the standard outlines the physical properties of IG-01, system design considerations, usage limits, and key safety aspects relevant for system designers, installers, and end-users. SIST EN 15004-7:2018 aligns with and modifies ISO 14520-12:2015 to address European requirements for fire safety and firefighting systems.
Key Topics
Applications
SIST EN 15004-7:2018-compliant IG-01 gas extinguishing systems are widely used in scenarios where rapid, residue-free fire suppression is crucial and water-based systems may cause damage. Typical applications include:
- Data centers and server rooms: Protecting electronic equipment from fire damage without risking short circuits or water damage.
- Telecommunications facilities: Safeguarding critical communication infrastructure.
- Power plants and electrical substations: Ensuring continuity of power supply by protecting switchgear, control rooms, and electrical panels.
- Archives, museums, and libraries: Preserving valuable documents and artifacts sensitive to heat, humidity, or liquid extinguishing agents.
- Chemical storage and processing areas: Providing a safe alternative where chemical reactions with traditional agents could be hazardous.
- Marine and offshore installations: Used in machinery spaces and control rooms where space and environmental concerns are paramount.
Related Standards
For enhanced system design, installation, and maintenance best practices, refer to the following associated standards:
- EN 15004-1:2017 – Fixed firefighting systems – Gas extinguishing systems – Part 1: Design, installation, and maintenance.
- ISO 14520-12:2015 – Gaseous fire-extinguishing systems – Physical properties and system design for IG-01 (as modified in this standard).
- EN 15004-2 to EN 15004-10 – Covering other extinguishant options such as FK-5-1-12, HFCs, HCFC blends, and other inert gases.
- CEN/TS 54 series – Addressing fire detection and alarm systems for integration with fire extinguishing systems.
By complying with SIST EN 15004-7:2018, designers and facility managers ensure that IG-01 gas extinguishing systems operate safely, effectively, and in line with recognized European fire safety requirements. This standard is essential for ensuring reliable protection of sensitive and high-value environments across various industries.
