Fire Is A Very Significant Threat In Comparison To Any Other Danger. If A Fire Starts Anywhere And Isn’t Put Out Quickly, It Kills A Lot Of People And Damages A Lot Of Property. Because Fire Spreads Quickly From One Location To Another, It Causes A Lot Of Destruction Anywhere. In This Article, I Am Going To Give Complete Information About What Is Fire And What Are The Ways To Stop It.
In Addition, This Article Contains Comprehensive Information About The Fire Triangle. First Of All, I Will Tell You The Definition. What is fire? Fire Triangle, Fire Tetrahedron And Safety Prevention.
What is fire?
At High Temperatures, Rapid Oxidation Is What Causes Fire. It Produces Energy In The Form Of Heat, Light, And Radiation That Cannot Be Seen. In Layman’s Terms, Fire Is A Chemical Reaction In Which A Flammable Substance Rapidly Oxidizes Or Burns.
After Understanding Its Definition, It Is Very Important To Understand How Fire Starts, For This Let Us Understand Fire Triangle Kya Hai. To Ignite And Burn Anything, Fire Requires Three Elements: – Heat, Fuel And Oxygen.
What Is A Fire Triangle?
The Fire Is Put Out Or Put On Hold By Removing One Of These. Fire Occurs Naturally When The Right Mixture Of These Three Elements Is Present. The Fire Will Go Out If One Of The Three Mentioned Things Is Taken Out.
- Heat – Electricity, Smoking, Static Sparks, Open Flames (Welding, Cutting), Hot Surfaces, Friction
- Fuel – Wood, Paper, Cloths, Gasoline, Solvents, Alcohols, Propane, Butane, Hydrogen
- Oxygen: To Burn, All Flammable Materials Require Oxygen (O2). Oxygen Is Usually Available In Sufficient Quantity (21%) In The Air. At Least 16% Oxygen Must Be Present For A Fire To Burn.
For Many Years The Concept Of Fire Was Represented By The Fire Triangle Of Combustion Described Above And Represented By Fuel, Heat, And Oxygen. Further Fire Research Determined That A Fourth Element, A Chemical Chain Reaction , Was A Necessary Component Of Fire.
The Fire Triangle Was Changed To The Fire Tetrahedron To Reflect This Fourth Element. The Fire Tetrahedron Is Described As A Pyramid.
What Is Fire Tetrahedron?
Note That The New Definition Basically States That In Order For A Fire To Start, All Four Elements—Fuel, Heat, Oxygen, And A Chemical Chain Reaction—Must Be Present. Removing Any One Of These Essential Elements Will Extinguish The Fire.
Fire Extinguishing – Methods Of Extinguishing Fire
As I Told You Above, If Any One Of These Four Elements Is Removed, The Fire Will Be Extinguished. The Procedures For This Are As Follows:
- Smothering: Smothering Is The Process Of Removing Oxygen From A Fire.
- Starvation- The Process Of Removing Fuel From A Fire Is Called Starvation.
- Cooling- The Process Of Removing Heat From The Fire Is Called Cooling.
- Interference- Applying Extinguishing Agents That Stop The Chemical Chain Reaction.
Fire Classifications ?
The Classification Of Fire Is Also Very Important To Know After Knowing About Fire. Fires Are Classified On The Basis Of The Fuel They Burn. You Must Have Seen A, B, C, D Etc. Written On All Fire Extinguishers, This Means That You Can Extinguish These Types Of Fires With That Fire Extinguisher . The American System Divides Fire Into Four Categories:
1. Fires Of Class A:
These Are Fires That Happen When Common Flammable Materials Like Cloth, Wood, Paper, Rubber, And A Lot Of Plastics Catch Fire. The Most Effective Extinguishing Agent For This Is Water, And Dry Chemical Powder Is Prescribed For A, B, And C Fires.
2. Class B Fires:
These Are Fires Caused By Flammable And Combustible Liquids Like Alcohol, Solvents (Acetone), And Motor Gasoline. Fire Extinguishers That Extinguish This Type Of Fire Include: Foam, Dry Chemical, CO2, Halons.
3. Class C Fires:
Fires Involving Energized Electrical Equipment In Which The Extinguishing Agent’s Electrical Non-Conductivity Is Crucial. Water Or Any Extinguisher Containing Water Or Any Agent Mixed With Water Is Not Permitted To Be Used On Fires Involving Energized Electrical Equipment, As Water Is A Good Conductor Of Electricity, Causing A Risk Of Electrocution.
Fire Extinguishers That Extinguish This Type Of Fire Are: Dry Chemical, CO2, Halons
4. Class D Fires:
These Are Fires That Involve Metals Like: Sodium, Potassium, Magnesium Etc.
Special Types Of Fire Extinguishers Are Used To Extinguish Such Fires.
How To Do Fire Safety Prevention?
Fire Prevention Safety The Best Way To Fight Fires Is To Prevent Them. To Help Prevent Fires, The Following Measures Should Be Taken Into Consideration:
- Good Housekeeping Is The Key. Garbage Should Always Be Placed In The Proper Containers And Emptied Daily.
- Work Areas That Are Clean Are Safer Than Those That Are Messy Or Dirty.
- Those Who Smoke Should Smoke Only In Designated Areas And Never Leave Lit Cigarettes Unattended. Also, Never Smoke In Bed.
- Proper Storage And Handling Of Materials, Especially Flammable Materials.
- Keep All Flammable Liquids In Tightly Sealed Containers.
- Liquids That Are Flammable Should Be Kept Away From Heat, Flame, Or Sparks. Never Smoke Near Combustible Objects.
- Place All Waste That Is Flammable In Covered Metal Containers.
- Use Flammable Liquids Only In Well-Ventilated Areas.
- Clean Up Any Flammable Liquid Spills Right Away. Make Sure Electrical Connections Are Tight To Avoid Loose Connections That Could Cause Sparks.
- Avoid Connecting Too Much Wire To An Electrical Outlet.
Keep The Heater Away From Curtains And Furniture, And Do Not Use The Heater When Drying Clothes. - Always Use Fuses With The Proper Rating.
Conclusion
Remember That Most Of The Fires In Homes Or Factories Are Caused By Electrical Short Circuits. Therefore, You Have To Protect The Electric Equipment From Overloading And Apply The Measures Mentioned Above.
Frequently Asked Questions:
1. Fire: What Is It? Types Of Fire?
Fire Is A Process Of Rapid Oxidation At High Temperatures. It Releases Hot Gases, Light And Radiation As Invisible Forms Of Energy. In Simple Terms, Fire Is A Chemical Reaction That Involves The Rapid Oxidation Or Burning Of A Flammable Substance.
2. What Results From Fire?
Fire Is A Very Significant Threat In Comparison To Any Other Danger. If A Fire Breaks Out Anywhere And If It Is Not Extinguished In Time, It Causes A Lot Of Loss Of Life And Property. A Fire Anywhere Causes A Lot Of Destruction Because Fire Spreads From One Place To Another Very Quickly.
3. What Are The 4 Main Methods Of Extinguishing A Fire?
- Smothering- Smothering Is The Process Of Removing Oxygen From A Fire.
- Starvation- The Process Of Removing Fuel From A Fire Is Called Starvation.
