For flammable‑liquid and high‑value machinery spaces, special‑hazard systems complement sprinklers. Foam‑water systems (balanced‑pressure pump or bladder tank proportioners) protect tank farms, loading racks, and diked areas with monitors and foam chambers sized per risk. In turbine halls and paint lines, water mist suppresses fire with minimal collateral water damage and improved visibility; fine droplet distributions enhance heat absorption and oxygen displacement in enclosed volumes. Deluge systems with quick‑opening valves provide rapid area coverage for conveyors, cable trays, and transformers.
Integration with detection is where modern designs excel. Addressable fire alarm/releasing panels supervise valve status, linear heat/cable detectors, flame detectors, and programmable logic interlocks for safe sequencing (e.g., shutdowns, E‑Stops, ventilation control). Open‑protocol gateways publish critical points—valve positions, foam concentrate levels, pump status—to the BMS for centralized visibility and maintenance planning.
Commissioning combines hydrostatic tests, proportioner calibration, discharge/aspiration tests, pump acceptance, and end‑to‑end cause‑and‑effect verification. Foam acceptance includes density and expansion checks; water‑mist acceptance confirms pressure/flow envelopes at the most demanding nozzles. With lifecycle analytics and routine performance tests, plants sustain readiness without guesswork, ensuring that high‑hazard scenarios are controlled quickly while safeguarding people, assets, and the environment.
