Structural Fire Protection
Structural fire protection is the application of passive fire protection to load-bearing elements — including steel beams, columns, and concrete structures — to maintain their structural integrity for a specified period during a fire. Methods include intumescent coatings, spray-applied cementitious products, and fire-resistant board encasement, all specified to meet the fire resistance requirements of Approved Document B or BS EN 1993-1-2.

- Passive Fire ProtectionPassive Fire ProtectionPassive fire protection (PFP) comprises the structural and material elements built into a building to contain or slow the spread of fire and smoke without requiring activation — including compartmentation, fire doors, fire stopping, cavity barriers, and structural fire protection. PFP elements must comply with Approved Document B and are assessed as part of a fire risk assessment.View definition
- CompartmentationPassive Fire ProtectionCompartmentation is the division of a building into fire-resisting cells using walls, floors, ceilings, and fire doors, designed to contain a fire within its compartment of origin for a specified period — typically 30 or 60 minutes. It is a core element of passive fire protection and is required in all non-domestic premises under Approved Document B and assessed through every fire risk assessment.View definition
- Fire Resistance RatingPassive Fire ProtectionA fire resistance rating is the tested period — typically 30, 60, 90, or 120 minutes — for which a building element maintains load-bearing capacity (R), fire integrity (E), and thermal insulation (I) when exposed to a standardised fire. Ratings are specified by Approved Document B and BS 9999 for walls, floors, doors, and structural columns depending on building type, height, and occupancy.View definition
- Approved Document BFire Regulations & StandardsApproved Document B is the UK Building Regulations guidance document covering fire safety in the design and construction of new buildings and major extensions. It sets requirements for means of escape, internal fire spread, compartmentation, external fire spread, and access for the fire and rescue service, and references British Standards — including BS 5839 and BS 5266 — for specific technical requirements.View definition
- BS 9999Fire Regulations & StandardsBS 9999 is the British Standard providing a comprehensive, risk-based code of practice for fire safety in the design, management, and use of buildings. It offers an alternative compliance route to Approved Document B, enabling greater design flexibility through detailed fire engineering analysis. BS 9999 covers compartmentation, means of escape, detection, suppression, and management procedures across the full lifetime of a building.View definition

Requirements for structural fire protection in the UK depend on the type of premises and applicable legislation, including the Regulatory Reform (Fire Safety) Order 2005 and relevant British Standards. The responsible person for a premises must ensure adequate fire safety provisions are in place.
