After a Nuclear Detonation, You Will Have Fifteen Minutes to Figure Out How You Are Going to Breathe

Not fifteen minutes to run. Fifteen minutes before what the nuclear bomb blasted into the sky starts coming back down on the town you are standing in.

This is how the first fifteen minutes will go, and what comes after them. Read it slowly. Fifteen minutes is not long, and the difference between panic and being ready is knowing what is coming before it comes.

0:00

The flash.

A nuclear bomb goes off on an American city. In one flash it takes the whole city, the buildings, the highways, every person inside their day, at once. The power, the water, the phones, the hospitals, every road out, gone with it. The people who were there do not get fifteen minutes. They do not get one.

A place that took a hundred years to build stops existing before the sound of it reaches the next town. It is the worst thing a weapon has ever done, and it is over in seconds.

0:00 to 0:01

You are alive.

Wherever you are, the explosion has already ended, and it happened somewhere else.

That is the part you survive. It is not the part that decides what happens to you.

0:01

The clock starts.

Because that bomb has just blasted nuclear fallout miles into the sky, radioactive and fine enough to breathe, and it is already starting to come back down.

It will take about fifteen minutes to start settling. The wind decides where. Hundreds of miles before tomorrow, a thousand by the day after, and it does not check which towns were near the blast.

0:01 to 0:15

The only fifteen minutes that matter.

Fifteen minutes to get to safety. Fifteen minutes to seal everything you can, the windows, the doors, the vents. And fifteen minutes to work out how you are going to breathe for the next several days without poisoning yourself.

Not fifteen minutes to think about it. Fifteen minutes to already have the answer.

0:05

What most people will be doing.

Standing outside. Looking at the sky. Trying to call someone on a phone that doesn't connect. Trying to figure out what just happened.

Panicking, confused, and breathing. Most people will not understand what is happening to them until long after it has happened.

0:15

The fallout arrives.

And nothing changes that you can see, because the fallout is invisible. The sky stays blue. There is no smell, no taste, no feeling.

But from this minute on, every breath puts radioactive particles into your lungs, and it does not matter how far you are from the blast. The wind has carried the poisonous fallout to your street.

This is the moment that matters

From this minute, you are either breathing filtered air or you are not. There is no middle ground and no way to tell by feel. Every breath of unfiltered air pulls radioactive particles into your lungs, where they stay and keep giving off radiation into your cells. Once that starts, it cannot be reversed.

Hour 1 to hour 6

Nothing is coming.

The trucks stop. The stores are stripped in the first hour by the people who understood first. The drivers stay home, breathing the same air as everyone else.

Whatever is in your house right now is what you have for the three days of fallout ahead. That includes whatever you are using to breathe.

Hour 1 to hour 72

Inside you.

Once you breathe it in, the radiation attacks your cells from the inside. Your blood. Your organs. Quietly.

You will feel fine. For three days the air stays deadly and you will feel fine, and by the time the symptoms appear, the damage is irreversible.

By the time it tells you it was there, there is nothing left to do about it.

None of this is a secret

The fifteen minutes come from Homeland Security's own emergency planning for a nuclear detonation.

And Homeland Security has been warning about a nuclear attack from China or Russia, and about Iran trying to get revenge on us with nuclear warheads while it fires at our forces today.

Hour 72

Two doors on the same block.

When the three days of fallout are over, two doors on the same block open onto the same street.

Behind one, someone spent the fifteen minutes looking for something they didn't have, and the three days of fallout breathing whatever came through the walls, feeling fine until they didn't.

Behind the other, someone spent the fifteen minutes opening a closet and putting on a gas mask bought on an ordinary day months earlier. Every breath since has been clean.

Same block. Same fifteen minutes. The only difference was what was already in the closet.

So what are you going to do when the nuclear fallout comes? Because the only thing that can filter nuclear fallout out of the air is a gas mask with a nuclear-rated filter.

What the mask actually does

That's why I bought one for every person in my family.

This is the strongest gas mask on the market. It protects you from everything in the air that can hurt you. In those fifteen minutes, you take it off the shelf and put it on, and the clock stops mattering, because your lungs get nothing but clean air. The air around you is poison. The air through the filter is clean. That is the entire difference.

Nuclear-rated filter. It catches radioactive particles before they ever reach your airways.

Eat and drink with it on. It never has to come off while the air outside is still dangerous.

Anti-fog lens. You can see, the whole time.

Waterproof, dustproof, shockproof. It won't crack, won't shatter, and won't fail when you are depending on it.

Filter lasts over 50 years. You buy it once, put it in a closet, and it is ready for the rest of your life.

Staying inside won't do this job on its own. Houses breathe. Air comes in through vents, cracks and window frames, and you breathe whatever comes in with it. Sealing your home buys you time. The filter is what gets you through the 72 hours of fallout.

This is the decision point

Fifteen minutes is enough time to open a closet. It is not enough time to order anything, drive anywhere, or find a store with one left. The mask costs less than a night out, it takes up less room than a shoebox, and in those fifteen minutes it is the only thing between your lungs and three days of poison air.

The fifteen minutes start when they start

Not when you are ready. The people who get those fifteen minutes right will be the ones who finished getting ready on an ordinary day like this one, when the sky was blue for the normal reason.

Waiting is the one plan that can't work. The day the fallout becomes real, everyone will want one of these at the same time, and there will be nothing left to buy.

With all the crazy stuff going on right now and all the other wars in the world, this is not the time to take chances. It is better to have something you don't need than to need something you can't get.
