Can explosives be used to put out fires?
The blast knocks the flames off the fuel source, putting out the fire. In the case of wildfires, Doig says, an explosion could knock the fire out of intensely burning trees and onto the ground, where firefighters could more easily reach it. “As soon as the flame doesn’t have access to fuel anymore, it stops burning.”
What is the only thing that can extinguish wildfire?
Wildfire is a highly volatile material; when ignited, it can explode with tremendous force and the resulting fire burns so hot that water cannot extinguish it. Only by smothering the flames with large quantities of sand can they be put out.

Can dynamite put out a fire?
Using dynamite to “blow out” the fire by forcing the burning fuel and oxygen away from the fuel source. This was one of the earliest effective methods and is still widely used. In the 1930s mechanical jaws were developed to clamp off the pipe below the fire, but they are seldom used today.
Can a vacuum be created to extinguish fire depriving it of oxygen?
Instead of spraying out extinguishing agents at a fire, the Vacuum Extinguish Method (VEM) sucks the flames and burning materials into a vacuum chamber, where they can be safely suffocated or extinguished.
What do firefighters do to stop wildfires?
Firefighters control a fire’s spread (or put it out) by removing one of the three ingredients fire needs to burn: heat, oxygen, or fuel. They remove heat by applying water or fire retardant on the ground (using pumps or special wildland fire engines) or by air (using helicopters/airplanes).
Are there still wild fires in California?
There are three active, large fires burning in California and they have burned 202,805 acres. There has been no growth in a couple of weeks, so while they are listed as “active” because they are still burning, for our purposes they are listed as past because of the high level of containment.
Does gunpowder detonate?
Gunpowder is a low explosive: it does not detonate, but rather deflagrates (burns quickly). This is an advantage in a propellant device, where one does not desire a shock that would shatter the gun and potentially harm the operator; however, it is a drawback when an explosion is desired.
Should the Air Force bomb wildfires to put them out?
Rather than fighting wildfires in the traditional way — using aircraft to drop chemical retardants on the blaze while ground crews clear brush that fuels the flames — the Air Force should try to put them out by bombing them, wrote F-15E Strike Eagle weapons systems officer Mike Benitez in War on the Rocks Aug. 1.
Can guided bombs put out a fire?
In the piece, Benitez suggests a technique whereby guided bombs are dropped on a fire, emitting a shockwave that snuffs out airflow behind it and temporarily slows a fire’s spread. While the idea sounds like something a bomber pilot itching for extra flight time cooked up at happy hour, there is a precedent for such an operation.
Why are explosives used to put out oil and gas fires?
For years, explosives have been used to put out tough-to-tame oil and gas fires. That basically involves sending a shockwave down a well and hoping for the best. It makes good scientific sense.
What are fuel-air explosives (FAE)?
Fuel-Air Explosives [FAE] disperse an aerosol cloud of fuel which is ignited by an embedded detonator to produce an explosion.
