On July 28, 2025, southem Taiwan experienced an extreme rainstorm, with over 360 mm of rainfall in just six hours in the Chiayi region. The construction site of the TSMC Chiayi AP7 advanced packaging plant suffered from severe flooding. Although the flooding was confined to construction zones and did not affect critical equipment, this sudden “flash flood" sent a strong waring to the semiconductor industry: under accelerating climate change, flood risks have become an unavoidable operational threat for high-techmanufacturing sites.
For semiconductor fabs-where cleanrooms, highly sensitive processes, and costly equipment are central-any water ingress can result in catastrophic business interruption. As a professional manufacturer of FM Approved Quick-Fit Compression Flood Barriers.Shanghai Weiwang Technology provides a best-in-class solution based on the globally recognized FM Data Sheets FMDS 1-40 (Flood) and FMDS 7-7 (Semiconductor Manufacturing Facilities).
FM Standards:The Global Benchmark for Semiconductor Flood Protection
FM's Property Loss Prevention Data Sheets (FMDS) are widely adopted across high-risk industries worldwide. For semiconductor plants, two key documents define the gold standard for flood resilience:
FMDS 7-7- Semiconductor Manufacturing Facilities: Zero Tolerance for Water intrusion
Section 1.2 of FMDS 7-7 identifies fluid leakage as a critical threat to uninterrupte doperations. The standard explicitly prohibits locating wafer fabs or critical systems within100-or 500-year flood zones (§2.3.2.1.2), reflecting a “zero tolerance" approach to flood risk-especially in cleanroom environments.
FMDS 1-40-Flood: Business Continuity Comes First
FMDS 1-40 emphasizes that the core goal of flood protection is to ensure uninterrupte doperation (§2.1).lts key recommendations include:
·500-Year Flood Protection Standard: Facilities must be protected against floods with a 0.2% annual exceedance probability (i.e., 500-year event), with an additional 0.3 to 0.6meters of freeboard (§2.2.1).
·Stricter Measures for Cleanrooms: Areas where water ingress is unacceptable must apply enhanced flood protection measures (§3.6.1).
Lessons from TSMC: Speed and Opening Protection Are Critical
The TSMC incident highlights how flash floods can occur with little warning and rapidly rising water levels. Traditional flood protection measures such as sandbags or beam-type barriers often fail to deploy in time.
More critically, openings such as loading docks, driveways, and entrances remain the most vulnerable points of any building. FMDS 1-40 §2.2.6 explicitly warns:
“lf all water entry points are not adequately protected, flood loss may be unavoidable.”
Therefore, the adoption of FM Approved flood barriers with rapid deployment capability isessential for high-tech facilities.
Solution: Designed for the Semiconductor Industry
Shanghai Weiwang Technology has developed a proprietary FM Approved Quick-Fit Compression Flood Barrier, engineered to meet the strictest FM standards and provide thefollowing three core advantages:
✅International Certification: FM Approved, Ultra-Low Leakage Rate
In accordance with FMDS 1-40 §2.2.6.2.4, FM Approved flood barriers are strongly recommended. Our products have passed FM Approvals testing, achieving a leakage rate of less than 1 L/hr/m, far superior to typical commercial products—providing reliable protection for cleanrooms and sensitive equipment.
✅Rapid Deployment System: Quick Installation During Emergencies
The tool-free quick-fit design allows facility teams to deploy the barriers within a very short response time, significantly reducing flood-related risks. This meets FMDS 1-40 $3.7 requirements for fast response and outperforms traditional beam-type systems under extreme weather scenarios.
✅Compression-Seal Technology: Active Protection with Zero Tolerance for Leakage
Using a mechanical compression mechanism, our flood barriers maintain outstanding sealing performance and structural stability even under high hydrostatic pressure. Compared to passive pressure-based seals, our active sealing technology delivers superior resilience and watertight performance.
Conclusion: Flood Protection ls Not a Cost-lt's a Strategic Investment
The TSMC Chiayi flood event reminds us that extreme weather is no longer an exception— it’s the new normal. Flood protection should be treated as a core business continuity investment, not an optional expense.
Shanghai Weiwang Technology is committed to providing FM standard-compliant flood protection solutions with exceptional performance and reliability. Our FM Approved Quick-Fit Compression Flood Barriers are the optimal solution for helping high-tech manufacturers meet FMDS 1-40 and 7-7 requirements while ensuring uninterrupted operations even during extreme climate events.
