How Can HPR Assets Worth Tens of Billions Pass FM Approval? End-to-End Firestopping Protection for Semiconductor Fabs

How do 10-billion HPR assets pass FM audits? Full-chain firestop protection for semiconductor Fab,

TKC has you covered!

Every wall penetration is a potential “high-speed corridor”

Semiconductor wafer fabs (Fab) are recognized as High-Value, Protected Risk (HPR) assets. Cleanrooms are densely filled with complex piping, cable trays, and exhaust systems; in the event of a fire, any non-compliant wall penetration can become a channel for fire and toxic smoke spread.

For semiconductor owners, passing the stringent audits of international insurers such as FM is not only a compliance baseline — it's the key leverage to obtain preferential insurance premium rates.

Pain points: the “construction black box” under rigorous scrutiny

Firestopping for semiconductor fabs generally faces two major challenges:

① Frequent non-standard conditions: A large number of special wall-penetration nodes not covered by drawings exist; arbitrary on-site handling easily leads to failure in FM audits;
② Breaks in the responsibility chain: Material compliance does not equate to system compliance — if the installation team lacks systematic training, human errors will directly cause the fire compartmentation to fail. Once issues are exposed, the owner and general contractor will both face huge rework costs and joint liability risks.

Full-chain solution: TKC FM4991-certified firestop contractor

As one of Asia’s rare FM globally certified installation organizations, Shanghai Tengxi provides full-chain protection for Fab projects from assessment to delivery:

Before construction｜Systematic assessment and compliance planning

On-site DRI (Designated Responsible Individual) together with the material vendor issues compliant Engineering Judgment (EJ) drawings to eliminate speculative on-site construction; non-standard nodes will be documented and governed

During construction｜FM4991 zero-tolerance quality installation

Each firestop is installed strictly according to the certified detail catalog; the DRI is on-site throughout for oversight. An independent file is created for each location: site photos, GPS coordinates, and full records of material batches

After construction｜Airtightness testing and delivery verification

Strictly carry out DoorFanTest in accordance with NFPA2001FM5-32. Issue comprehensive inspection reports for the envelope structures of cleanrooms and gaseous fire-extinguishing rooms. Perform conformity acceptance spot checks of the firestop system in accordance with ASTME2174E2393. Let the data speak, ensuring every project can withstand FM insurance audits
