3 Things You Must Never Do During a Typhoon: The First One Has Ruined Countless Families.

Every time a typhoon approaches Taiwan, all sorts of "typhoon preparation hacks" circulate across the internet. However, many of these are based on misconceptions that can actually increase danger. Instead of relying on urban legends, it is crucial to embrace scientifically sound disaster preparedness. Here are three of the most common—and dangerous—mistakes people make during a typhoon that you must avoid.

1. Do Not Open Windows to "Balance Pressure"

This is a long-standing myth. Many believe that cracking a window open during a typhoon helps balance indoor and outdoor air pressure, reducing the chance of glass breakage. In reality, this is the exact opposite of what you should do. Allowing strong gusts of wind to enter your home increases internal air pressure, which can cause severe structural damage—such as ripping off ceilings or breaking windows—and pose serious safety risks.

Correct Safety Procedures:

• Keep all windows and doors tightly closed and locked.
• Stay away from large floor-to-ceiling windows.
• If necessary, draw the curtains to minimize the risk of injury from flying glass shards.

Note: The viral "tape a cross (米 shape) on glass" tip only helps keep broken glass together; it does not prevent the glass from shattering in the first place.

2. Avoid Coastlines, Riverbanks, and Flooded Areas

During every typhoon, people risk their lives to capture "dramatic" photos of giant waves or torrential rain. This is incredibly dangerous. High winds, storm surges, and sudden tidal surges can sweep anyone into the sea in an instant.

Furthermore, flooded areas are deceptive traps:

• Hidden open manholes can cause falls.
• There is a significant risk of electrocution from submerged electrical components.
• Vehicles are highly susceptible to getting stuck or stalling.

Areas such as underpasses, mountain roads, and riverbanks are high-risk zones during heavy rain and should be avoided at all costs.

3. Do Not Trust Unverified Online Rumors

During a typhoon, social media is often flooded with misinformation, such as "guaranteed work/school cancellations," "saltwater as disaster prevention," or "fake official alerts about super typhoons." Much of this information is unsourced or consists of recycled old news. Misinformation doesn't just cause panic—it can lead people to make life-threatening mistakes.

Always rely on official sources:

• Central Weather Administration (CWA)
• National Fire Agency (NFA)
• Local government disaster response platforms

Effective typhoon safety is not about urban legends; it is about early preparation, staying indoors, and monitoring official updates. Staying in a sturdy building with emergency lighting and drinking water is far more effective than any "quick fix."
