Elazığ City Hospital — FM200 Gas Suppression Project

In a city hospital, fire safety is not the job of a single system but of complementary layers. Sprinklers and wet systems protect occupied areas; but in the critical technical spaces that hold data, power and imaging, water is not the solution — it is a new risk. On the Elazığ City Hospital project, A-Pro Engineering protected all of these critical spaces with FM200 (HFC-227ea) clean-agent suppression — hospital-wide, including electro-mechanical infrastructure works, turnkey.

Why Clean Agent in Hospitals?

In critical technical spaces, water extinguishes the fire while destroying expensive equipment and process continuity:

• Server and data rooms — patient records and hospital automation live on this hardware; water means permanent data and equipment loss.
• Medical-imaging (MRI/CT) control areas — devices are extremely sensitive to water and moisture.
• UPS, battery rooms and main electrical boards — in these power-continuity spaces water is ineffective and hazardous.

In these spaces FM200 extinguishes without residue, without electrical conductivity and within seconds — stopping the fire while keeping the facility operational.

Suppression in a Seismic Region: Structural Resilience

Elazığ is in a first-degree seismic zone. However well a suppression system is designed, it is useless if, during an earthquake, the pipework fractures, the cylinder bank topples or the supports fail. So on this project:

• pipework and distribution manifolds were sized to seismic support/bracing principles,
• cylinder banks were anchored and restrained against overturning,
• details were resolved so that movement and displacement would not overstress the system.

The goal is clear: the system must stay operational precisely when it is most needed — including after an earthquake.

Why FM200 (HFC-227ea)?

FM200 is an NFPA 2001 clean agent; it extinguishes by rapidly absorbing heat and breaking the chemical chain reaction, without lowering oxygen to dangerous levels:

• Fast discharge — typically reaches design concentration within 10 seconds.
• Occupied-space safety — concentration kept within the safety threshold (NOAEL).
• Residue-free — no residue, corrosion or clean-up burden; the space returns to service quickly.
• Compact storage — stored as a liquid in pressurised cylinders, suitable for tight technical spaces.

Turnkey Electro-Mechanical Delivery

A-Pro Engineering carried the project from a single source:

1. Engineering design — per-space volume and agent calculation, layout and discharge design.
2. Procurement — agent, cylinder banks, nozzles, detection and control panels.
3. Electro-mechanical works — seismically braced pipework, support systems, electrical and control wiring.
4. Installation — cylinder banks, nozzles and detection equipment.
5. Testing and commissioning — room-integrity, functional and scenario tests.

Detection and Commissioning

To prevent accidental discharge, each protected space used cross-zoned detection: suppression only activates once mutually confirming detectors verify the fire. Audible-visual alarms, a pre-discharge delay and manual release/abort stations were integrated. During commissioning, room-integrity tests verified the agent’s required hold time.

Outcome

At Elazığ City Hospital, all critical technical spaces were secured with a seismically resilient FM200 clean-agent suppression system that respects the demands of the seismic zone — delivered from a single source, from design to commissioning. Together with İkitelli City Hospital, this project reinforces A-Pro Engineering’s experience with gas suppression at city-hospital scale.
