The First Hours of a Disaster

A fire, a flood, a major storm, an earthquake, an evacuation order β€” the first hours decide the most, and panic is the enemy. You can't control the disaster; you can control your next few moves.

First, if life is in danger right now: call your local emergency number (e.g. 911, 112, 999) and do exactly what local authorities and official alerts tell you. Their instructions for your situation always override anything on this page.

When disaster hits, the difference between a bad day and a tragedy is often just the order you do things in. You don't have to be brave or skilled β€” you have to be calm enough to follow a simple priority: get safe, then decide whether to stay or go, then take care of people and stay reachable. Property comes last and can always be replaced. Here's the order, and the handful of life-safety rules that matter most.

The one idea: people before property, always β€” and official local instructions before everything. Get to safety first, make the stay-or-go call on what authorities say (and go early if you go), then account for your people and keep one way to reach each other.

Get to safety first

The immediate danger depends on the disaster. Act on official alerts, but the broadly accepted basics:

Two rules that save lives: never enter floodwater on foot or by car ("Turn Around, Don't Drown"), and never assume a downed power line is dead β€” stay far back and report it.

Stay or go?

If authorities say evacuate β€” go, and go early

Don't wait to "see how bad it gets." Roads jam, conditions worsen, and the people who leave early get out safely. Take your go-bag, your people, and pets; leave the rest.

If told to shelter in place β€” do

Sometimes leaving is more dangerous than staying. Follow the instruction, get to the safest part of your building, and keep listening to official updates on a charged phone or battery radio.

Know two ways out

If you may need to leave, picture two different routes out of your area in case one is blocked, and a place to head for (a relative's, a shelter, anywhere safer).

What to grab (only if it's safe)

If you have a go-bag, take it and leave. If not, this is the short list β€” but never delay getting to safety to collect things:

Reaching people when networks fail

Text, don't call

When networks are overloaded, short text messages often get through when calls won't. Keep messages brief to save battery and bandwidth.

Use one out-of-area contact

Local lines may be down, but a friend or relative far away can act as the hub everyone checks in with. Agree on this person in advance if you can; it's far easier than everyone calling everyone.

Protect your battery, agree a meeting point

Switch to low-power mode, dim the screen, and close apps β€” your phone is your lifeline. If you're separated and can't connect, a pre-agreed meeting place outside the danger area is the fallback.

If you're staying put (storm or blackout)

Carbon monoxide is the silent killer after storms. Never run a generator, grill, camp stove, or any fuel-burning engine indoors, in a garage, or near windows β€” only well outside. It has no smell and is often fatal.

First-hours checklist

In rough order.

The close

In the first hours, you don't need a plan for everything β€” you need the right order and a few hard rules. Get yourself and your people safe before anything else. Make the stay-or-go decision on what the authorities say, and if you're leaving, leave early and light. Keep one thread of contact alive, and protect your phone like the lifeline it is. And remember the rules that quietly kill the unprepared β€” floodwater, downed lines, and fumes indoors. Everything else is replaceable. Stay calm, go in order, and you give yourself and the people you love the best possible chance.
