Industrial Fire Suppression Systems
Industrial fire suppression systems protect factories, manufacturing areas, plant, machinery, storage and specialist risks using suitable water mist, sprinkler or other suppression technologies. NPHS supports industrial projects from early risk and system review through installation, commissioning, documentation and planned maintenance.
Send us your drawings, fire strategy, process information or existing system records and we can review the most appropriate next step.
Industrial water mist and sprinkler systems
Industrial sites often contain several different fire risks within the same building or estate. Production areas, storage, machinery, plant rooms and electrical spaces may each need a different suppression approach.
NPHS works with main contractors, M&E contractors, consultants, facilities teams, manufacturers, property owners and asset managers across new-build, refurbishment and existing industrial sites.
We can assess water mist, conventional sprinklers and specialist suppression against the actual process, fire load, available water supply, building layout and maintenance requirements.
For mixed-risk sites, that may result in several protection zones rather than one suppression technology being applied everywhere.
Industrial suppression starts with the process and hazard
A factory floor, warehouse, machinery enclosure and electrical room should not automatically be treated as the same suppression risk.
Production & process
Heat, ignition sources, oils, solvents, combustible materials and machinery can affect both system selection and protection objectives.
Storage & logistics
Commodity type, packaging, storage configuration, racking and height can materially change sprinkler requirements.
Plant & equipment
Enclosures, ventilation, fuel sources, electrical equipment and downtime risk can point towards water mist or specialist suppression.
“Our initial check looks at building use, fire strategy, water supply, available space and the relevant standard.”

What fire suppression is suitable for factories?
The right suppression system depends on the fire hazard rather than the word “factory” on the building description.
Large production and storage areas may lend themselves to conventional sprinkler protection. Machinery, plant and enclosed risks may be suitable for water mist where appropriate system testing supports the application.
Some electrical, process or specialist hazards may require a different suppression technology altogether.
Mixed industrial premises may therefore use a zoned approach with different systems protecting different areas.
| System route | Where it may be considered |
|---|---|
| Industrial sprinklers | Factory floors, production areas, storage and wider open industrial spaces. |
| Industrial water mist | Suitable machinery, plant, enclosed equipment and process applications supported by appropriate testing. |
| Specialist suppression | Specific electrical, process, flammable-liquid or high-value risks where the chosen agent suits the hazard. |
| Zoned protection | Industrial sites containing materially different production, storage, plant and equipment risks. |
Industrial system review:
System suitability should be established against the actual hazard, relevant standards, fire strategy, insurer requirements and available technical evidence.
Where are industrial water mist systems used?
Water mist can suit selected industrial risks where fine water droplets, reduced water demand or compact pipework provide useful technical or installation benefits.
Machinery spaces
Enclosed machinery applications may suit water mist where the system has appropriate fire-test evidence for the hazard.
Plant rooms
Equipment layout, ventilation, heat release, ignition sources and maintenance access all need assessment.
Generator areas
Fuel source, enclosure conditions, ventilation and equipment configuration affect system suitability.
Turbine & equipment enclosures
Targeted water mist may be considered where the tested application matches the equipment and risk.
Process risks
Selected manufacturing processes may suit water mist where the fire hazard and system evidence support its use.
Water mist is application-specific. The proposed hazard needs to fall within appropriate test evidence and system design limits.
Sprinkler protection for factories and manufacturing sites
Automatic sprinkler systems remain an established suppression route for many industrial buildings, production areas and storage risks.
The design needs to reflect the hazard classification, building configuration, stored materials, water supply and any additional project or insurer requirements.
Hazard classification
The process and materials within the protected area influence sprinkler design requirements.
Storage configuration
Commodity, packaging, racking and storage height can materially affect protection requirements.
Water supply
Flow, pressure, pump duty and storage arrangements need to meet the selected system design.
Building layout
Compartmentation, ceiling configuration, obstructions and production equipment need coordination.
Insurer input
Industrial projects may carry insurer or client requirements beyond the basic project specification.
Maintenance access
Valves, pumps, test points and system components must remain practical to inspect after handover.
What needs to be understood before a system is designed?
Industrial fire suppression design needs information about the operation as well as the building. Process hazards, materials, storage, equipment and future access can all affect system selection.
Heat-producing machinery, sparks, fuels, oils, solvents, dusts or combustible packaging can change both the likelihood and behaviour of a fire.
Business continuity may also be significant where downtime to critical manufacturing equipment carries substantial operational cost.
The suppression design therefore needs to work around the real site, not just the architectural floor plan.
NPHS can join an industrial project wherever you need us
Clients can involve NPHS before the suppression route is fixed, during detailed design and construction, at commissioning stage or years later when an existing system needs inspection or maintenance.
Early risk review
Review building use, process risk, drawings, fire strategy, available water and potential suppression routes.
Existing specification
Take forward a defined sprinkler, water mist or specialist suppression requirement and coordinate delivery.
Installation & commissioning
Coordinate pipework, equipment, interfaces, programme, testing and project handover.
Existing industrial system
Inspect suitable installed systems, identify defects and establish an appropriate maintenance route.
You do not need to have used NPHS for the original installation to ask us to review a suitable existing suppression system.
What standards apply to industrial fire suppression?
The relevant standard depends on the selected system and the actual industrial hazard.
For conventional automatic sprinkler systems, BS EN 12845:2015+A2:2026 is the current British Standard covering design, installation and maintenance of sprinkler systems in buildings and industrial plants.
For fixed water mist systems, BS EN 14972-1:2020+A1:2025 provides the current general framework for design, installation, inspection and maintenance.
Application-specific water mist fire-test standards and evidence also need to be identified for the hazard being protected.
Fire strategy, risk assessment, insurer requirements and other project-specific criteria can also affect the final route.
| Reference | Industrial relevance |
|---|---|
| BS EN 12845:2015+A2:2026 | Automatic sprinkler system design, installation and maintenance for buildings and industrial plants. |
| BS EN 14972-1:2020+A1:2025 | General design, installation, inspection and maintenance framework for fixed land-based water mist systems. |
| Application-specific fire testing | Supports whether a particular water mist system is appropriate for the industrial hazard. |
| Fire risk assessment | Identifies workplace fire hazards, people at risk and required fire precautions. |
| Fire strategy / specification | Defines how suppression fits with the wider building and operational fire safety approach. |
| Insurer requirements | May influence sprinkler design, water supplies, protection objectives or inspection requirements. |
Industrial compliance route:
NPHS supports suppression design and delivery. Final requirements remain dependent on the project, responsible person, fire strategy, insurer and relevant approval or enforcement route.
Our industrial fire suppression process
The scope can begin with system selection or with a developed specification ready for installation.
Project review
Review drawings, process information, fire strategy, risk areas and existing suppression requirements.
System planning
Confirm the suppression route and coordinate pipework, nozzles or sprinklers, pumps, tanks and interfaces.
Installation
Deliver the agreed package around the industrial programme, access requirements and other trades.
Commissioning & handover
Complete relevant tests and provide the agreed project documentation for the building or facilities team.
Maintenance
Continue with planned inspection, servicing, defect reporting and remedial support after handover.
Fire suppression maintenance for industrial sites
Industrial suppression systems need planned inspection and maintenance so that their condition, operation and records remain under control.
Factories also change over time. Machinery moves, production lines are altered, racking changes and new services can affect suppression coverage or access.
NPHS can inspect and maintain suitable existing water mist, sprinkler and specialist suppression systems, including systems originally installed by another contractor.
System condition+
Inspect applicable pipework, heads or nozzles, valves, equipment and visible system components.
Pumps & water supplies+
Review relevant pump, tank, water-supply and control arrangements.
Building changes+
Consider whether altered machinery, storage, partitions or services may affect the existing protection.
Faults & remedials+
Record defects and identify repair, investigation or modification requirements where appropriate.
Service records+
Provide maintenance documentation for the responsible person, facilities team or asset records.
Why use NPHS for industrial fire suppression?
NPHS supports industrial projects across water mist, sprinkler and specialist suppression technologies.
Contractors and consultants can involve us during design or tender. Manufacturers and facilities teams can approach us when a live site needs installation, commissioning, inspection or maintenance support.
Our focus is on matching the suppression route to the actual industrial risk, coordinating the system with the wider project and leaving useful documentation for the people who will manage it afterwards.
That support can continue long after the original project has been handed over.

FAQs
Where are industrial water mist systems used?
Industrial water mist systems can be used for suitable machinery, plant, generator, turbine, enclosure and process risks where the proposed system has appropriate fire-test evidence for the application. Building layout, ventilation, process conditions and maintenance requirements also need review.
What fire suppression is suitable for factories?
Factories may use automatic sprinklers, water mist or specialist suppression depending on the process, materials, storage, fire load, ignition sources and building configuration. Sites containing several different risks may need a zoned approach rather than one system throughout.
Can water mist be used instead of sprinklers in an industrial building?
Water mist may be suitable for specific industrial applications where appropriate testing supports the hazard and the project requirements accept that route. It should not be treated as a universal replacement for conventional sprinklers across industrial or storage areas.
What standard applies to industrial sprinkler systems?
BS EN 12845:2015+A2:2026 is the current British Standard covering automatic sprinkler system design, installation and maintenance in buildings and industrial plants. Additional insurer, client or project requirements may also apply.
What standard applies to industrial water mist?
BS EN 14972-1:2020+A1:2025 provides the general design, installation, inspection and maintenance framework for fixed water mist systems. The proposed industrial application also needs suitable application-specific fire-test evidence.
Do industrial fire suppression systems need regular maintenance?
Yes. Inspection and maintenance requirements depend on the installed system, relevant standard, manufacturer information and site conditions. Changes to machinery, storage or building layout should also be considered because they can affect the original suppression design.
Can NPHS maintain an industrial system installed by another contractor?
NPHS can assess suitable existing fire suppression systems even where another contractor completed the original installation. Existing drawings, commissioning records, manufacturer information and previous service reports are useful when establishing the appropriate inspection and maintenance route.
What information does NPHS need for an industrial fire suppression quote?
Useful information includes building drawings, process details, machinery information, storage arrangements, ceiling heights, water-supply data, fire strategy requirements and any insurer specification. Existing-system enquiries should also include commissioning and maintenance records where available.
