Industrial & Manufacturing
Your warehouse or distribution center carries the highest fire-protection engineering burden of any occupancy class. Storage height, commodity class, and process hazards all drive system design — and getting the classification wrong means the system won't control a fire under its own design assumptions.
How we work with industrial & manufacturing
Industrial fire protection is not plug-and-play. The sprinkler density required for a 40-foot high-piled rack storage warehouse storing idle pallets is materially different from one storing cartoned unexpanded plastics, and different again from a manufacturing floor with flammable liquid processes. NFPA 13 Chapter 20 and IFC Chapter 32 govern high-piled storage; getting the commodity classification wrong means the system won't control a fire under its own design assumptions. Our industrial sprinkler work starts with a commodity class determination and a hydraulic calculation, not a rule-of-thumb head count.
If your facility carries FM Global insurance, you're working with a second layer of requirements on top of NFPA minimums: FM DS 8-9 for storage, FM DS 2-0 for alarm and signaling. We work directly with FM Global data sheet requirements and can coordinate pre-acceptance testing with your underwriter's field engineer — so the FM inspection isn't the first time anyone checks whether your system meets their thresholds.
Manufacturing occupancies add process-hazard complexity: flammable liquids require NFPA 30 compliance and possibly foam-water or dry-chemical suppression; welding operations trigger NFPA 51B hot-work permit programs; combustible dust creates deflagration risk addressed under NFPA 652 and 654. We handle special-hazard suppression design for these environments and can assist with NFPA 652 dust hazard analysis (DHA) documentation when your process generates combustible dust.

Frequently asked questions
How is high-piled storage defined, and why does it matter for sprinklers?
IFC §3203 defines high-piled combustible storage as solid-pile, palletized, or rack storage over 6 feet high for high-hazard commodities, or over 12 feet high for general commodities. Above those thresholds, NFPA 13 Chapter 20 and IFC Chapter 32 impose specific sprinkler discharge densities, in-rack sprinkler requirements, and fire department access requirements that are more stringent than standard warehouse design. Getting the commodity classification wrong — or defaulting to light-hazard design in a storage building — is one of the most dangerous design errors in commercial construction.
Does a distribution center need in-rack sprinklers?
It depends on commodity class and storage height. NFPA 13 Table 20.1.1 establishes whether ceiling-only protection is acceptable or whether in-rack sprinklers are required. For cartoned unexpanded plastics stored over 25 feet, in-rack sprinklers are typically required regardless of ceiling sprinkler density. The hydraulic calculation must confirm the ceiling system can meet its design criteria even with in-rack heads present. Zion performs full storage calculations from scratch — we don't rely on legacy systems that may have been designed for a different commodity mix.
What does FM Global require above and beyond NFPA?
FM Global Data Sheet 8-9 for storage occupancies typically requires specific sprinkler k-factors, maximum storage heights by commodity class, and clearances from the deflector to top of storage that NFPA 13 permits in some configurations but FM does not. FM also performs their own pre-acceptance inspection on new systems. Zion has worked on FM-insured facilities in the DFW market and can provide the FM-specific submittal documentation your underwriter's engineer will expect.
How often must a fire pump be tested in Texas?
NFPA 25 §8.3.1 requires a weekly churn test (no-flow test) for electric-drive fire pumps, and annual flow testing to verify the pump curve against the design point. Diesel-drive pumps require a 30-minute weekly run. The annual flow test must be documented and the results compared to the pump's certified curve — if the pump is degraded more than 5% from the rated curve, NFPA 25 requires evaluation and corrective action. Zion performs and documents both tests to NFPA 25 standards.
Our facility generates combustible dust. What fire protection applies?
NFPA 652 requires a Dust Hazard Analysis (DHA) for any facility that generates, processes, or handles combustible dust. NFPA 654 covers dust fire and explosion prevention for general industries. Depending on the DHA findings, the facility may need explosion suppression, deflagration venting, spark detection, or enhanced housekeeping protocols — on top of standard fire suppression. Zion can assist with the DHA documentation and design the fire protection response the analysis requires.
