Passive Fire Protection

Comprehensive surveys and assessments of fire doors, compartmentation, and structural fire protection systems

Critical First Line of Defense

Passive fire protection (PFP) forms the foundation of your building's fire safety strategy. Our specialized surveys assess the integrity of fire-resistant barriers, ensuring they will perform as designed to contain fire and smoke, protecting escape routes and preventing fire spread.

Following high-profile incidents and regulatory changes, passive fire protection has become a critical focus area. Our surveys help you understand the condition of your PFP measures and provide clear guidance on maintaining their effectiveness.
