Why don't firemen drop big blocks of dry ice on fire to put them out? Wouldn't that smother the fire pretty efficiently?

Because is much easier to use liquid water?

But the volume of water you have is the volume that is useable. The dry ice sublimates and covers a much larger area than the original block's volume making it several times more efficient than water in terms of transporting volume to effected area of fire. Also in California where there's a severe drought and constant wildfires it seems like this would be a better option.

Take a wild guess what the 2nd link is.

Even if dry ice were to work like you had just described, what would happen to people that were at a lower altitude than where the dry ice was dropped. Would they not suffocate as well?
Some fire extinguishers are like dry ice so in a way they do. They use different methods to put out different types of fires.

I'm suggesting for wildfires, not house fires. Water is fine for smaller fires but a wildfire is difficult to manage with water. And I'm not saying replace water with this, you'd drop water immediately after dispersing the gas to suffocate the flame to cool the area and add a layer of moisture to prevent it from combusting again.

For certain types of fires, co2 is used. Co2 is more expensive than water however, and firemen would have to bring their own rather than just tap into the nearest hydrant.
Also, in the situation you're describing, the firemen would have little control over the co2. They couldn't target flames.
Ice is a solid and therefore much heavier than liquid water you fucking idiot.

He said dry ice so it has already been dehydrated and is therefore lighter than water, moron.
