Things to Know About Passive Fire Protection in the Aviation Sector
We at BSML are passive fire protection specialists with experience supporting those in the aviation sector. Passive fire protection reduces fire spread by design rather than action. It is a quiet, but vital, layer of safety that works alongside active systems such as sprinklers, alarms and suppression equipment.
Core requirements of Passive Fire Protection
Understanding the core requirements starts with recognising the key aims. Passive systems must limit fire and smoke movement, protect structural integrity and allow safe evacuation and firefighting access. In aviation settings these aims translate into strict zoning of terminals, hangers, service tunnels and plantrooms. Materials and installation must meet civil aviation authority standards and local building regs.
Key elements and what they mean
Compartmentation keeps fire and smoke in one zone and gives evacuation routes more time. Fire rated doors and walls are chosen for performance, not appearance. Fire stopping seals around cable trays, ducts and pipe penetrations to maintain compartmentation. Structural fire protection involves applying dry linings or installing fire rated boarding to improve fire resistance.
You should:
- Regularly survey fire stopping and seals for damage or unauthorised penetrations
- Use tested materials that are certified for the aviation environment
Passive fire protection measures for aircraft infrastructure
Maintenance shops, hangars, fuelling areas and baggage systems each pose different challenges. For hangers the focus is on large open spans and rapid evacuation. For terminals it is onward spread via services and voids that matters most. We advise detailed risk assessments that map out vulnerable routes for fire and smoke.
Aviation passive protection compliance and inspection
Compliance is not just a one off task. Inspections should be scheduled and recorded. Typical checks include:
- Visual inspection of seals and barrier integrity
- Verification of fire rated door operation and signage
- Confirming materials have current certification and installation matches test conditions
Documentation matters. Keep logbooks so you can demonstrate ongoing compliance to inspectors and insurers.
Practical advice for procurement and contractors
- Specify performance criteria
- Ask for third party test evidence and insist on competent installers who follow manufacturers guidancee
- During refurbishments protect fire compartments and avoid temporary penetrations that are not sealed quickly
- Treat passive fire protections as an integral part of any building work not an afterthought
Passive fire protection is the foundation of safety in the aviation sector. It often works unseen, yet it saves time and lives when every second counts. If you need a partner to survey your passive systems or carry out works, get in touch with us today.
