Indoor Hazards: Even Safe Buildings Can Be Dangerous

Most earthquake injuries don’t come from collapsing buildings, they happen inside. Falling furniture, shattered glass, and blocked exits can all turn a “safe” space into a dangerous one.

When people think of earthquake safety, the focus is often on whether a building will remain standing. Structural collapse is indeed the most catastrophic risk, but it is not the only one. In fact, even when buildings survive an earthquake with little to no visible damage, the inside can quickly turn into a dangerous environment. Understanding and addressing these indoor hazards is an essential part of earthquake preparedness.

Why Indoor Hazards Matter

During major earthquakes, many injuries and even fatalities are not caused by collapsing structures but by falling or shifting objects inside buildings. Bookshelves, televisions, kitchen appliances, ceiling lights, and even everyday items like flowerpots or picture frames can become dangerous projectiles.

Earthquake-resistant buildings are designed to prevent collapse, but they cannot stop items inside from toppling or breaking. This means that personal safety depends not only on construction strength but also on how we prepare our living and working spaces.

Real-Life Lessons

  • Japan’s 1995 Great Hanshin-Awaji Earthquake showed that while many reinforced buildings survived, unsecured furniture caused severe injuries.

  • The 2011 Great East Japan Earthquake highlighted risks from falling objects in schools and offices, where injuries occurred despite structurally sound buildings.

  • California earthquakes have repeatedly demonstrated that televisions, computers, and heavy furniture are among the most common sources of preventable injuries.

These cases remind us that even in a safe building, people may still be at risk.

Common Indoor Dangers

  • 1. Falling Furniture – Tall cabinets, bookshelves, and wardrobes can easily tip over.

  • 2. Sliding Electronics and Appliances – TVs, microwaves, and computers may slide off stands or counters.

  • 3. Broken Glass – Windows, mirrors, and dishes can shatter, creating sharp debris.

  • 4. Obstructed Exits – Fallen furniture may block doors or hallways, making evacuation difficult.

  • 5. Ceiling Fixtures – Lights, fans, and hanging decorations can detach during strong shaking.

How to Reduce Indoor Risks

  • Fix Heavy Furniture with brackets or safety straps.

  • Secure Electronics and Appliances using non-slip mats or earthquake gel pads.

  • Keep Heavy Items Low so they are less likely to fall on someone.

  • Install Cabinet Locks to prevent dishes or glassware from flying out.

  • Clear Exit Routes regularly to ensure safe evacuation.

  • Check and Maintain Safety Devices like straps and latches to ensure long-term effectiveness.

A Combined Approach to Earthquake Safety

True earthquake preparedness is twofold:

  • 1. Structural Safety – Buildings must meet or exceed seismic design standards to prevent collapse.
  • 2. Indoor Safety – Homes, schools, and workplaces must be arranged and secured to minimize injury from falling objects.

Only by combining these approaches can we ensure that surviving an earthquake does not depend on luck alone.

Earthquake Preparedness: More Than Just Strong Walls

Earthquake safety is not just about strong buildings—it’s about safe interiors.

By recognizing the dangers posed by unsecured furniture, appliances, and objects, and by taking simple preventive steps, individuals, families, and communities can protect themselves from avoidable injuries.

True safety means protecting not only the building, but also the people and lives within it.
