Fire Safety After Earthquakes — “Most Post-Quake Fires Start Small—But Spread Faster Than You Can Imagine”

After major earthquakes, fires often break out due to damaged gas lines, electrical shorts, overturned stoves, and broken heating equipment. With weakened buildings and blocked roads, even small fires can turn into large-scale urban disasters. As a disaster specialist, I explain the essential steps to stay safe during post-quake fire risks.

■① Check for Fire Hazards Immediately After Shaking Stops

Once the shaking ends, act fast. Check for:

• The smell of gas
• Sparks or smoke
• Fallen heaters or stoves
• Damaged electrical wires

Early detection prevents small fires from becoming deadly.

■② Shut Off Gas and Electricity If You Suspect Damage

To reduce fire risk:

• Turn off the gas valve if you smell leaks
• Shut off breakers if wiring is damaged
• Do not use open flames
• Avoid plugging in devices until inspections are complete

One simple action can prevent an entire building from burning.

■③ Keep a Fire Extinguisher Accessible and Know How to Use It

A portable extinguisher can stop a small fire before it grows. Remember the PASS rule:

• Pull the pin
• Aim at the base of the fire
• Squeeze the handle
• Sweep side to side

Only attempt if the fire is small and escape routes are clear.

■④ Evacuate Immediately if a Fire Is Growing

Post-earthquake environments make firefighting difficult. If flames spread:

• Evacuate without hesitation
• Crawl low under smoke
• Close doors behind you to slow fire
• Move to an open area away from buildings

Smoke inhalation is the leading cause of fire-related deaths.

■⑤ Stay Away From Fire-Damaged or Leaning Buildings

After a fire:

• Do not reenter burnt structures
• Avoid walls weakened by heat
• Watch for falling debris
• Follow official safety inspections

Buildings damaged by both earthquakes and fire are extremely unstable.

■Summary

Fire safety after earthquakes requires rapid inspection, shutting off utilities, and decisive evacuation when necessary. Even small fires can escalate quickly in damaged buildings. Preparedness and immediate action protect families from one of the most underestimated post-quake dangers.
