Technical data enables construction and fire industry professionals to assess and specify Automist as an alternative to a domestic water mist system

Automist is designed to help compliance with building fire regulations, particularly in open plan layouts. Such products are permitted under Building Regulations as long as they
have been tested and shown to be fit for purpose. A similar framework of requirements exists for the Fire Safety Order and the Housing Act. Automist’s testing was conducted
by BRE and is framed around demonstrating a survivable set of conditions in the room of
origin of the fire, to minimise the toxic gas / low oxygen / heat exposure an escaping
person would experience.

The fire hazards that Automist was tested against were taken by BRE directly from DD8458-1 (the draft water mist standard) and BS EN 1869 (the standard for testing fire blankets on chip pans). These represent a serious fast-growing furniture fire and a kitchen oil fire and are tests well known in the industry.

The recently updated issue of Building Regulations Approved Document B has placed more emphasis on active fire protection systems rather than passive systems, such as enclosed staircases and even fire rated doors, favoured in the past and architects are finding that an Automist system incorporated in their projects can afford them increased design freedoms, integrity and flexibility.
