Fire safety advisor for factories, warehouses and buildings

Enter length × width × height or floor area, pick (or type) the business activity and the building structure. The tool infers the fire hazard class and fire resistance, checks design appraisal under Appendix III of Decree 105/2025/ND-CP (replaced by Decree 347/2026/ND-CP) and proposes a solution for each system with rough quantities.

Sources and assumptions. Basis: Law on Fire Prevention, Fighting and Rescue 55/2024/QH15; Appendix III of Decree 105/2025/ND-CP, replaced by Appendix III of Decree 347/2026/ND-CP (effective 15/09/2026). Summaries state Decree 347/2026 keeps the storey, area and volume thresholds; values come from excerpts and are marked ⚠ pending the official text. Building hazard class per QCVN 06:2022/BXD. Results guide the procedure and do not replace the appraising authority. ⚠ = code table value to be checked against the original standard. Preliminary results for material selection and budgeting; not a substitute for an approved fire protection design.

Recommended solution

ItemVerdictProposed solutionBasis
Fire safety design appraisalRequiredMeets the threshold of item 10: 2,000 m² floor (threshold 2,000) or 14,000 m³ (threshold 15,000).

Frequently asked questions

Does a 2,000 m², 7 m high timber warehouse need fire design appraisal?

Yes. A timber warehouse is class C. Item 10 of Appendix III: class A, B, C warehouses from 15,000 m³ or from 2,000 m² floor area. The volume of about 14,000 m³ is below the limit, but 2,000 m² reaches the area threshold.

Does a large steel warehouse need appraisal?

Warehouses of bare steel and metals without combustible packaging are usually class D or E, not covered by item 10, so not listed regardless of size ⚠. Areas holding plastic pipe, timber or goods in paper or plastic packaging may become class C.

If not listed, is anything required?

Yes. No appraisal certificate, but design, construction and equipment must comply with QCVN 06:2022/BXD and QCVN 10:2025/BCA (see the Required fire equipment tool), and inspections still apply to facilities under fire management.

Who carries out acceptance from 01/07/2026?

The owner organises acceptance and is responsible. Police inspection of acceptance results was abolished in favour of post-inspection ⚠.
