- evaluating the effectiveness of an explosion suppression system;
- evaluating the scale up of an explosion suppression system to larger than tested volumes;
- development and evaluation of design tools for explosion suppression systems;
- installation, operation and maintenance instructions for an explosion suppression system.
This document is applicable only to explosion suppression systems intended for the protection of closed, or essentially closed, enclosures in which an explosion could result as a consequence of ignition of an explosible mixture, e.g. dust-air, gas(vapour)-air, dust-gas(vapour)-air and mist-air.
This document is not applicable for explosions of materials listed below, or for mixtures containing some of those materials:
- unstable materials that are liable to dissociate;
- explosive materials;
- pyrotechnic materials;
- pyrophoric materials.

Overview
The SIST EN 14373:2022/kprA1:2024 standard, developed by CEN, establishes essential requirements for explosion suppression systems intended to protect closed or nearly closed enclosures. These systems are critical safety solutions designed to prevent the escalation of explosions caused by ignitable mixtures such as dust-air, gas(vapour)-air, dust-gas(vapour)-air, and mist-air environments. The standard details the design, application, and evaluation methods for these systems, enabling consistent and effective protection against explosive hazards.
This document specifically excludes unstable, explosive, pyrotechnic, and pyrophoric materials, focusing exclusively on environments where suppression can mitigate ignition events in enclosed spaces.
Key Topics
Design Requirements
The standard outlines fundamental design criteria for explosion suppression system components ensuring reliability and compliance with safety benchmarks.Effectiveness Evaluation
It specifies rigorous test methods to assess how effectively explosion suppression systems extinguish or control explosions when triggered.Scaling-Up Procedures
Procedures are provided to evaluate the performance of suppression systems when scaled to volumes larger than those physically tested, enabling safe application in diverse industrial settings.Development of Design Tools
The document supports developing and validating analytical and computational tools for designing explosion suppression systems.Operational Guidelines
It includes instructions and best practices for the correct installation, operation, and ongoing maintenance of explosion suppression systems to maintain optimal safety levels.
Applications
SIST EN 14373:2022/kprA1:2024 is applicable in any industrial context where containment of explosive mixtures in closed enclosures presents a risk. Common industries leveraging these systems include:
- Chemical and pharmaceutical manufacturing
- Grain processing and storage facilities
- Paint and solvent production
- Metalworking plants handling combustible dust
- Petroleum refining and gas processing
Implementing explosion suppression systems compliant with this standard helps businesses significantly reduce risk by:
- Enhancing worker safety
- Protecting valuable equipment and infrastructure
- Ensuring regulatory compliance with EU Directives and regulations
- Minimizing downtime due to explosion-related incidents
Related Standards
For comprehensive explosion protection, SIST EN 14373:2022/kprA1:2024 is used alongside other pivotal standards in explosion safety, such as:
- EN 14491 – Explosion isolation systems
- EN 15089 – Explosion venting devices
- EN ISO 80079-series – Equipment for explosive atmospheres
- ATEX Directives – European guidelines for equipment and protective systems intended for use in potentially explosive atmospheres
Together, these standards form an integrated framework for effective explosion prevention, protection, and mitigation strategies across various industries.
Adhering to SIST EN 14373:2022/kprA1:2024 ensures reliable development and deployment of explosion suppression systems that meet stringent performance and safety requirements, playing a vital role in occupational safety and operational continuity in hazardous environments.
