Firefoam poppers explained

[Jimyoda]

The firefoam popper is a device that will extinguish all flames in its radius when it pops.

Activation
A firefoam popper is triggered in one of two ways:

• It is triggered automatically when it catches fire.
• It can be triggered manually by a colonist directed to it via the mouse right-click.

Once activated, it will spark for about two seconds before it bursts into a spray of foam extinguishing all flames in a 19 x 19 area. Pawns on fire will also be extinguished. The explosion does not damage structures or colonists. The firefoam popper destroys itself when it pops, making it a one-time use device.

Firefoam
The residual firefoam prevents fire. This provides very effective protection against inferno cannons and any other type of incendiary. To intentionally leave firefoam in place, remove the home area to prevent colonists from cleaning it up. The area would also need to be roofed because rain and snow quickly wash away firefoam, in about two game hours.

Although firefoam fireproofs an area, it makes for an ugly environment. Firefoam indoors has beauty of -25; outdoors it has beauty of -7.

Pawns passing through firefoam move about 25% slower.

Edit: Added a bit more info.

Does the firefoam popper leave behind any resources when it destroys itself upon use?

Does the firefoam popper leave behind any resources when it destroys itself upon use?

Good question.  No, it doesn't leave behind any construction materials after it pops.

Does the firefoam slow down pawns whilst they cross it?

[Jimyoda]

Does the firefoam slow down pawns whilst they cross it?

Yes. Firefoam definitely slows down pawns walking across it. Walking speed is reduced by about 25%.

hey, thx Jimyoda! I assumed firefoam poppers would hav a much smaller area of effect. maybe they  actually would be a good addition to my colony...

Never gotten A chance to use/install them.

Never gotten A chance to use/install them.

I recomend them, i keep one in each area i dont want to lose, such as battery rooms (after the first time i had a zzzt destroy a room and charbroil a pawn i installed them which is where i learned to love them) in freezers or storage areas, main crafting area of my base, outdoor wooden greenhouses that i havent been able to upgrade ect.

Things are a god send in many many cases, i even kept a few outside my base incase fires got crazy till i figured out concrete is a great fire break i also keep one at the door and in the middle of my hydroponics greenhouses, nothing ruins your day faster then a fire taking out an entire rooms worth of hydroponics.
