2 Regulations, Codes and Standards

Approved Document B1 (Means of Escape) and B3 (Internal Fire Spread Structure) of the Building
Regulations 2000 for England and Wales details alternative ways in which the integrity of compartments
may be maintained where ductwork penetrates fire separating elements.

Similar details are contained in Technical Standards Parts D & E (Scotland) and Technical Booklet E
(Northern Ireland). The Regulatory Reform (Fire Safety) Order 2005 replaced most fire related legislation in
England & Wales on the 1st October 2006.

Other useful documentation relating to the fire protection of buildings includes:

• Department of Health HTM 05 Series including:
HTM 05-01 Managing Healthcare Fire Safety
HTM 05-02A Guidance in Support of Functional Requirements
HTM 05-03 Operational Provisions

• DFES Building Bulletin 100 - Design for Fire Safety in Schools
• London District Surveyors Association Fire Safety Guides including Fire Safety Guide No 1 - Section 20
Building: 1997
• Fire Prevention Association (FPA) Design Guide for the Fire Protection of Buildings

The most detailed and informative guides specifically related to fire resisting ductwork are the ASFP
(Association for Specialist Fire Protection) Blue Books - British Standard & European versions.

BS 9999:2017 Code of Practice for Fire Safety in the Design Management and use of Buildings details the
four principle methods of protection as follows:

Method 1 Protection using Fire Dampers (thermally actuated)
Method 2 Protection using Fire Resisting Enclosures
Method 3 Protection using Fire Resisting Ductwork
Method 4 Protection using Fire and Smoke Dampers (automatically actuated via smoke detectors)

There are a number of Standards related to the testing of products suitable for use as fire resisting
duct systems as follows:

British Standards
BS 476 Pt24:1987 Method for the determination of the fire resistance of ventilation ducts

European Standards
BS EN 1366-1:2014 Fire resistance tests for service installation - Ventilation ducts
BS EN 1366-8:2004 Fire resistance tests for service installation - Smoke extraction ducts
BS EN 1366-9:2008 Fire resistance tests for service installations - Single compartment smoke
extraction ducts
BS EN 12101 Part 3: Specification for powered smoke and heat exhaust ventilators

International Standards
ISO6944-1:2008 Fire resistance tests - Ventilation ducts
ISO6944-2:2009 Fire resistance tests - Kitchen extract ducts
