This matters because you need a gallon of water to put out every 3 square feet that’s on fire. By the way, a hose spraying 300 gallons of water a minute can fill about 8 bathtubs at once! But let’s see how much fire it can put out.
How do you extinguish a forest fire?
To put out a fire, heat, fuel or oxygen must be removed. Putting dirt and water or retardant on fire removes the oxygen from the fuel. This allows a firefighter using a hand tool such as shovel, axe, rake or Pulaski to extinguish small fires.
How do you calculate how much water you need for fire fighting?
The basic formula in the schedule is: NFFi= (Ci)(Oi)(X +P)i Where NFFi = needed fire flow (NFF) in gal per min (L/min) Ci = a construction factor that depends on the construction of the structure under consideration Oi = an occupancy factor that depends on the combustibility of the occupancy (X = P)i = an exposure …
Why don t they use sea water to put out forest fires?
The salt from using ocean water would ruin the local ecosystem, making it so that no plants would grow in that forest for decades. C) The salt would also accelerate oxidation of metals that it comes in contact with causing cars to start rusting away.
What is the best Defence against fire?
As always, the best defense against a fire is to be prepared. Take a moment to look at your fire extinguisher.
How do you calculate fire flow?
Fire flow = length X width ÷ 3
This formula is most easily applied if the estimated square footage of the entire structure is used to determine an approximate fire flow for the total structure and is then reduced accordingly for various percentages of fire involvement.
How do you calculate fire load?
How to Calculate Fire Load
- Determine the weight of combustible materials in the compartment for which you wish to calculate fire load. …
- Determine the value of these materials in calories. …
- Determine the area of the compartment. …
- Multiply M by C and divide the total by A to determine the fire load.
What chemicals are in forest fires?
All smoke contains carbon monoxide, carbon dioxide and particulate matter (PM or soot). Smoke can contain many different chemicals, including aldehydes, acid gases, sulfur dioxide, nitrogen oxides, polycyclic aromatic hydrocarbons (PAHs), benzene, toluene, styrene, metals and dioxins.
How do forest fires affect rivers?
Wildfires can have immediate and long term effects on rivers, lakes, and streams. After burning vegetation, the ground’s soil becomes hydrophobic and is unable to absorb any water. This creates what is known as stormwater runoff. … These floods introduce heavy metals from ash and soil into waterways.
How humans can prevent wildfires?
10 Tips to Prevent Wildfires
- Check weather and drought conditions. …
- Build your campfire in an open location and far from flammables. …
- Douse your campfire until it’s cold. …
- Keep vehicles off dry grass. …
- Regularly maintain your equipment and vehicle. …
- Practice vehicle safety.
Is salt good for putting out fires?
If there’s no lid nearby, douse the fire with plenty of salt or baking soda. Salt will smother the fire almost as well as covering it with a lid, while baking soda chemically extinguishes it. … Avoid using flour or baking powder, which can explode in the flames instead of snuffing them out.
Why can’t California use ocean water to fight fires?
Fire can be put out with seawater, though it is not usually used to do so. Saltwater can effectively extinguish fire, but it may damage firefighting equipment and hurt plant life if used. Saltwater use creates problems for both the water distributing equipment and the surrounding environment.
