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

• Physical Properties of IG-01

  • IG-01 (Argon) is a colourless, odourless, electrically non-conductive inert gas.
  • High purity: minimum 99.9% by volume.
  • Boiling point: –185.9 °C; freezing point: –189.4 °C.
  • Non-toxic and does not produce harmful residues after discharge.
  • Zero ozone depletion potential (ODP) and zero global warming potential (GWP).

• System Design Requirements

  • Covers gaseous fire-extinguishing systems operating at nominal pressures of 160 bar, 200 bar, and 300 bar at 15 °C.
  • Fill pressures and maximum container working pressures are defined to ensure operational safety.
  • Specifies design concentrations and required extinguishing agent quantity for various hazard classes.
  • Systems must be designed to achieve targeted fire suppression concentrations, considering factors such as enclosure volume, temperature, and agent discharge time.

• Personnel Safety

  • Considers oxygen reduction risks and safety requirements for exposed personnel during and after system activation.
  • Sets thresholds for no observed adverse effect level (NOAEL) and lowest observed adverse effect level (LOAEL).
  • References EN 15004-1 for comprehensive personnel safety measures.

• Environmental Impact

  • IG-01 is environmentally benign due to its inert gas nature.
  • Ideal for use where sustainability and ecological safety are priorities.

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.
