Industries We Protect

A hospital cannot be emptied the way an office can. Patients in ICUs, operation theatres and dialysis units are non-ambulatory, so the strategy is horizontal movement into an adjoining compartment rather than a full building evacuation. That pushes the design toward zoned addressable detection that tells staff exactly which room is in alarm, staged alerting so wards are not thrown into panic, and smoke management that keeps escape corridors usable. Medical gas manifolds, generator rooms, records stores and pathology labs each carry their own hazard and are treated separately from ward areas.

Process areas rarely accept a single protection method. Flammable liquid handling and transformer yards call for foam or water-spray systems; open production lines and loading points may need a water curtain to stop fire spreading between bays; enclosed process skids and control rooms are better served by a gas suppression system that leaves no residue. Around all of this sits a conventional hydrant ring main with monitors for external and yard cover. Getting the boundaries right — where one system stops and the next begins — is the whole job, and it is decided by walking the plant, not by copying a previous project.

Water and live switchgear do not mix, and the electronics in an LT room or server hall are often worth more than the room. These spaces are protected with clean-agent flooding systems or CO2, released into a sealed enclosure by a dedicated detection panel, usually on a cross-zoned or double-knock arrangement so a single detector cannot trigger a discharge. Getting it right depends on things outside the cylinder bank: room integrity, damper and HVAC interlocks that shut airflow before release, pressure relief, and a manual abort for occupied spaces. CO2 systems carry a life-safety risk to anyone inside, so discharge delay, warning devices and lockout during maintenance are part of the design, not an accessory.
