KNOWLEDGE & COMPLIANCE

Understand the
reason behind the work.

Passive fire protection is shaped by law, statutory guidance, design requirements, standards, test evidence and the ongoing duty to keep fire precautions effective.

FIRAS
Law ≠ guidance ≠ standardsThis section deliberately separates legal duties from statutory guidance and technical standards.

FIRE DOORS

What purpose does a fire door serve?

A fire-resisting doorset protects an opening in fire-resisting construction. When correctly specified, installed, closed and maintained, it can resist the passage of fire — and, where smoke control is required, help restrict smoke — for its intended performance period. It is therefore part of the building's compartmentation strategy rather than an isolated product.

Restricts fire and smoke spread
Supports protected escape routes
Maintains compartment boundaries
Protects openings in fire-resisting walls
Depends on compatible components
Requires inspection and maintenance

INFORMATION MANAGEMENT

Golden Thread

For relevant higher-risk buildings, the building-safety regime includes requirements around prescribed digital information. More generally, traceable asset IDs, drawings, photographs, inspection records, installation records and revision history make passive fire protection easier to manage and verify over time.
