Public Safety
Ensuring Operational Continuity and Public Safety
Airports, rail systems, and highway tunnels combine public occupancy with electrical equipment, fuels, and restricted access. Fire protection needs to address the hazard at each location and the way detection, suppression, smoke control, and evacuation work together.
The projects below show Poseidon’s work in airport, transit, and tunnel environments. Selection and design discussions begin with the protected areas, occupancy, fire scenario, available utilities, and connections to existing safety systems.
Airports
Managing Complex Fire Hazards with Precision
Airport fire hazards range from fuel-handling areas to baggage equipment and control rooms. The fuel, equipment, occupancy, and operating conditions determine which suppression method is appropriate; a single agent is not suitable for every airport hazard.
At LAX Airport, Poseidon implemented a layered protection arrangement:
- Foam-Based Fire Suppression Systems: Foam suppression was used for the fuel-fire hazards. The foam concentrate, fuel compatibility, application rate, and discharge equipment need to be selected together to form an effective blanket.
- High-Pressure Water Mist Systems: Water mist was installed in baggage handling areas and control rooms. Suitability depends on the specific protected equipment and system design, rather than a general promise of zero equipment damage.
- Modular Fire Hose Systems: Adjustable nozzles with flow rates of 150 GPM supported the project’s response equipment. Trained teams must use the correct extinguishing medium, operating pressure, and application method for the fuel or chemical involved.
The project reduced fire-related downtime by 50%, improved compliance with NFPA 415 airport-terminal requirements, and strengthened operational resilience and passenger protection.
Rail Transit Systems
Ensuring Safety in High-Occupancy Spaces
Rail systems need fire protection suited to electrical equipment, passenger materials, confined spaces, and evacuation routes. Control rooms, train compartments, platforms, and tunnels can require different arrangements.
Poseidon’s rail protection work included:
- Clean Agent Suppression Systems: Clean agent suppression systems were used in control rooms and train compartments. The protected enclosure, agent concentration, occupancy conditions, and pre-discharge warning and release controls need to be matched to the application.
- Emergency Evacuation Lighting: Lighting in tunnels and platforms supported route identification during incidents.
- Portable Fire Blankets and Extinguishers: Fire safety equipment in staff compartments provided localized response tools for trained personnel working under the transit operator’s emergency procedures.
At the Chicago Transit Authority, Poseidon’s solutions achieved 40% faster evacuation times and reduced fire-related delays. Clean agent systems integrated with detection technologies supported safer operations for the millions of passengers using the network each year.
Highway Tunnels
Managing Fire Risks in Constrained Environments
Highway tunnels limit access and evacuation options while concentrating smoke, heat, and gases from a vehicle fire. Fire protection and emergency ventilation need to be coordinated with the tunnel layout, traffic conditions, and escape routes.
Poseidon’s solution for the Lincoln Tunnel included:
- Foam-Based Suppression Systems: Foam suppression addressed the relevant vehicle-fire hazards, with the agent and delivery arrangement matched to the fuel and intended application.
- Ventilation Systems: Fire detection was integrated with ventilation operating at airflow rates of 500 m³/min. Airflow alone does not establish safe breathing conditions; smoke movement, visibility, heat, toxic gases, and the location of escape routes also affect evacuation.
- Emergency Fire Hose Reels: Reels were positioned along the tunnel for deployment by trained personnel as part of the emergency-response arrangement.
The approach reduced response times by 35%, improved compliance with NFPA 502, and strengthened protection for motorists and emergency responders.
