BAFSA, the British Automatic Fire Sprinkler Association, has released a detailed technical guide titled “Using Water Mist Systems in Buildings and Structures”.

This document, published in November 2023, serves as a comprehensive resource on the application, design, and standards of water mist-based fire suppression systems.

Understanding water mist technology

Water mist systems are unique in their approach to fire suppression. They utilise fine water droplets to control, suppress, or extinguish fires.

The guide explains that unlike traditional sprinkler or gas extinguishing systems, water mist systems are highly specific to the application and the manufacturer’s technology.

Each system must be tailored to the particular hazard or occupancy it is designed to protect, based on the manufacturer’s Design, Installation, Operation, and Maintenance (DIOM) manual.

These systems are performance-based and require specific testing for each potential fire scenario.

The evolution of water mist systems

The guide traces the development of water mist systems, from early maritime applications to their expanded use in various sectors, including residential, commercial, industrial, and heritage buildings.

It outlines the importance of understanding the unique characteristics of water mist technology, particularly in relation to its application and effectiveness in different fire scenarios.

Key components and system types

The BAFSA guide provides detailed insights into the components of water mist systems, including nozzles, pumps, and control systems.

It differentiates between various types of water mist systems like open nozzle, automatic, and electronically controlled systems, each suited to different applications and fire hazards.

The document also addresses the importance of standards and certifications, ensuring that water mist systems meet rigorous safety and performance criteria.

Choosing the right system

A critical aspect of the guide is the emphasis on selecting the right water mist system for specific applications.

It underscores the necessity of following established standards and protocols and considering factors such as the fire hazard, occupancy, and environmental conditions of the intended application area.

Where to access the guide

The full guide can be accessed on BAFSA’s website, providing an invaluable resource for professionals involved in fire safety, including designers, engineers, and building managers.
