Regulations: Fire Safety in Scotland

Introduction

For fire safety, Regulations relating to the materials used in the external walls of relevant buildings have been made more robust with the requirement of A1 or A2 classified products, which will not contribute to the spread of fire.  For your convenience, we have outlined stove ventilation extracts from the following regulations:

Building Standards Scotland Technical Handbook – Domestic
Fire: Mandatory Standard 2.7 – Spread on external walls

2.7.0: There is a risk of fire spread on the external walls of a building … Therefore, the construction of external walls in taller buildings should not contribute to the development of fire or contribute to vertical fire spread up the facade of the building.  The 11m storey height in clause 2.7.1 and clause 2.7.2 is based on the reach capability of a fire and rescue service ground mounted water jet where there is sufficient pressure and flow in the water main.
