Fire Regulation - Volume 1 (B4)

Fire regulations Volume 1 - Sections B4

Construction of the External Walls

• Need to have fire resistance to prevent fire spreading

External walls

• Appendix A

• 1000mm of the relevant boundary should be met, Class 0

Space Separation

• Required space between buildings and adjacent buildings

• Fire spread damage and from collapsing

Assumptions

• Dwelling houses set out the sort of fire that will likely happen (based of things that are within the house)

• The use of the building determines the likely hood of what fire you get

• Only apply with small buildings surrounded by small buildings

Boundaries

• We assume that there is a set distance of the 4 walls

• New building and old building, creates the boundaries depending on the material of the old buildings material

• The boundaries are set to prevent spreading of fire from building to building

Unprotected Areas

• Materiality, and how it affects the boundaries

• The more unprotected area a wall has, the further the boundary must be from the exterior wall

• Canopies also change the boundary, as the canopy may collapse or jumping of fire will be a risk

Things that were the key parts of the section:

-> Materiality

-> Protection
