Approved Document B

The requirements for fire and smoke containment with respect to “means of escape” are contained in Approved Document B to the Building Regulations (England and Wales), Section 2 of the Scottish Technical Handbooks and Technical Booklet E to the Building Regulations (Northern Ireland).

These Approved Documents are not mandatory, they are only guidance. However, they are considered to be the usual means of proving compliance with the Building Regulations.
