water mist systems
There has been
much controversy over recent years about water mist systems being used for
fire suppression when design features are relaxed for building
regulations approval purposes, or other similar situations where premises
are regulated or licensed. This is due in the main to there currently
being no British Standard covering their design, installation and
Water mist systems
have been used for many years for marine applications, and have proved
extremely effective but their use in the built environment has been
limited. Many fire authorities however have been impressed by the
performance of such systems and have accepted their installation as
compensation for deviations from building regulations and other regulatory
advantage of water mist is the relatively small quantities of water used
in comparison to their sprinkler counterparts, typically only around
10%. This is an important
factor in premises such as historic buildings, libraries and document
archives where sprinklers may cause irreparable damage to valuable
disadvantages have been the high pressures normally required to generate an
effective water mist and the specialised pipe-work and control equipment
required to operate it. Maintenance has also proved to be an issue.
An innovative new
approach called 'Automist' has recently been launched by a company who won
the James Dyson award in 2009. Sir James Dyson is quoted as saying "this
simple but clever device should become a permanent safety feature in the
home. Smoke alarms are an essential part of modern life but have remained
fundamentally unchanged for 40 years. this device not only detects a fire
but can put it out as well".
The system can be
installed easily and cheaply into domestic property where it can usually
be run from a standard domestic mains water supply. In this picture the system is operating in a kitchen
where the mist
can be seen emitting from the base of the kitchen tap. Up to now the
system has only been tested on rooms up to 8m x 4m in size but will
probably develop to cover larger spaces in due course.
Automist has been
proved to be capable of rendering a normally lethal environment
survivable. In a major furniture fire, even those immobilised in the room
would have survived for the entire test period of 30 minutes. The system
is also effective on electrical and chip and fires, and can be
installed in rooms other than the kitchen, as can be seen below.
system is extremely cost-effective and will prove particularly beneficial
in many social housing situations and premises where the occupants are
vulnerable or at risk, however this type of system is undoubtedly an
extremely effective fire protection system in the domestic environment.
