🤔 How it works …….. ⁉
How do fire extinguishers work?
Fire happens when three things are in the same place at the same time:
Fuel: something to burn—such as wood or coal. Oxygen: usually from the air. Heat .
Fire-fighter involves breaking the fire triangle. which means removing either the fuel, the heat, or the oxygen.
Carbon dioxide (CO2) extinguishers contain a mixture of liquid and gaseous carbon dioxide (a nonflammable gas).
CO2 is normally a gas at room temperature and pressure. It has to be stored under high pressure to make it a liquid.
When you release the pressure, the gas expands enormously and makes a huge white jet.
CO2 attacks the fire triangle in two ways: it smothers the oxygen and, when it turns from a liquid back to a gas, it “sucks” in a massive amount of heat from its surroundings (the latent heat of vaporization), which cools whatever you spray it on by removing heat.
You’ll also find fire extinguishers classified by the types of fires you can use them on. This gives us five different kinds:
A: Green: For wood, cloth, and paper.
B: Red: For combustible and flammable liquids such as oil, gasoline, and paint.
C: Blue: For electrical equipment and tools.
D: Orange : For flammable metals.
K: Black: For animal or vegetable oils or cooking fats.
Inside, a fire extinguisher is quite like a giant aerosol can, often with two different substances inside.
One of them is a solid, liquid, or gas substance for fighting the fire.
The other one is called a propellant and is a pressurized chemical that makes the fire-fighting substance come out when you press the extinguisher handle.
😳Why❓❓❓
Choosing a black color for lawyer’s uniform!
Reason behind this is black is considered as a color of authority and dominance.
A person in black coat looks more powerful and impactful. Also black color represents submission to a certain thing, lawyers wear the black outfit to show their submission to justice. Black is a prominent color that offers a sheer elegance. It is observed that people wearing black outfits look more impactful and elegant.
Black is a colour which another can’t be painted on it. It neutral.it stands for defence and the white stands for purity this combo makes a lawyer look professional and it gives confidence to the client.
The white neckbands have their origins rooted in England. In the old English Courts, the barristers-at-law used to wear white bands as part of their uniform.
Since the Barristers were the first lawyers of Indian Courts, their dress was adopted as a symbol of advocates in our country.
The two pieces of white cloth joined together to form the advocate’s bands represent the Tablets of the Laws or Tablets of Stone.
These are the tablets that, according to the Christian belief, were used by Moses for inscribing the 10 commandments, which he received from a burning bush on Mt. Sinai.
The 10 commandments are believed to be the first example of a uniform coded law.
The shape of the band is also similar to the rounded off rectangular tablets. Thus, the white advocate’s bands represent the upholding of the laws of God and of men.
Wigs especially were supposed to bring anonymity to the Judge. Since in earlier times the people were discriminated on the basis of colour and ethnicity, standard form of wigs displayed unbiasedness and impartiality on the part of Judges that Judge did not belong to any one colour or creed but was an impartial, unbiased human being deciding the case.
