FEMA: don't forget to mask and social distance if taking shelter from nuclear blast

With Soviet Russian President Vladimir Putin putting his nuclear forces on high alert and not-so-subtly warning the West to not tempt him to use them, somebody decided to take a look at what FEMA suggests for citizens to do in the event of a nuclear explosion and noticed something that has now gone viral:

• Get inside the nearest building to avoid radiation. Brick or concrete are best.
• Remove contaminated clothing and wipe off or wash unprotected skin if you were outside after the fallout arrived.
• Go to the basement or middle of the building. Stay away from the outer walls and roof. 
• Try to maintain a distance of at least six feet between yourself and people who are not part of your household. If possible, wear a mask if you’re sheltering with people who are not a part of your household. Children under two years old, people who have trouble breathing, and those who are unable to remove masks on their own should not wear them.
• Stay inside for 24 hours unless local authorities provide other instructions. 
• Continue to practice social distancing by wearing a mask and by keeping a distance of at least six feet between yourself and people who not part of your household.

Wait.

Yes.

A top priority in the event of nuclear apocalypse is to mask and social distance while you take shelter with others from deadly radiation.

While some have reported that this was a recent change, according to the Wayback Machine at archive.org, social distancing and masking was added to the recommendations sometime on or around November 11, 2020, so it's not new, but it is a thing.

You can't make this stuff up.
