Boendesprinkler " residential sprinkler" med vattendimma

BRE i England har skrivit en guide för att underlätta för godkännande myndighet att möta frågeställningar kring vattendimma som skydd i boende miljöer, (boendesprinkler). Samtidigt har de samlat kunskap, för att sprida kunskap och slå hål på myter och missuppfattningar som finns kring vattedimma, precis som jag försöker göra med denna blogg.

I introduktionen går att läsa

This is a guide to water mist systems primarily intended for use by approving authorities, e.g.
building control bodies and fire safety officers, to detail current knowledge, improve education
about systems, to dispel myths/misunderstandings and to assist them in assessing water mist
systems in residential buildings that they may be faced with.
This guide also includes recommendations, cautions and commentary relating to the use of
water mist systems for life safety in residential building applications and suggests when it may
be appropriate to obtain specialist advice.
This guide applies to the majority of building types covered by Approved Document B6 (Fire
safety) Residential purpose groups, group 1 and the sleeping areas of group 2.
A water mist system is a fixed fire protection system, comprising components for automatic
detection and actuation, water supply delivery and water atomisation. A water mist system
discharges a spray of small water droplets.
Water mist systems are currently the subject of debate information about the overall
effectiveness of these systems for residential life safety applications is not well established.
Water mist systems have been demonstrated to be suitable and effective for the protection of
spaces on board ships and are an emerging technology for life safety building applications on
land. They have successfully been applied to protect assets, e.g. electronic equipment,
machinery spaces and deep fat fryers in buildings and now are being increasingly considered
for a range of building applications, e.g. for residential premises.
Assessment of water mist systems requires case by case review. This guide contains an
assessment checklist and pro-forma to assist building control professionals and fire safety
officers in coming to a judgement on the suitability of a particular water mist system for life
safety purposes in specific residential building applications.
Although this guide is focused on life safety applications, information and principles contained
in it may also be appropriate for water mist systems installed for property/asset protection.
However, it is recommended that insurers should be consulted for property/asset protection
This guide is not a regulatory document. It does not specifically cover water mist systems for
use in non building applications, non residential types of buildings, e.g. commercial and
industrial, object protection water mist systems or portable water mist systems.
