New edition of Approved Document B: Fire Safety - Volumes 1 & 2
This new edition of ADB replaces the 2006 edition and includes the amendments issued in November & December last year.
Approved Document B of the Building Regulations covers fire safety matters within and around buildings. Published in two volumes, Volume 1 deals solely with dwellings, including blocks of flats, while Volume 2 deals with all other types of building covered by the Building Regulations.
They come into effect on 30 August 2019.
The aim of these volumes are to set out guidelines that need to be followed in order to prevent the spread of fire over linings, such as walls or ceilings. Each volume also states what materials can be used and what British Standards each should conform to, to ensure that they provide the required level of protection.
The new edition of Approved Document B incorporates the following amendments:
- November 2018 which took affect on 21 December 2018
- December 2018 which took affect on 21 January 2019.
Full details on the above amendment booklets can be found here.
