Question

In fire extinguishers, which of the following is used?
A. $CHC{l_3}$
B. $C{S_2}$
C. $CC{l_4}$
D. $C{H_2}C{l_2}$

Answer 1

Hint: As we know that a fire extinguisher is a functioning fire security gadget utilized to stifle or regulate little flames, regularly in crisis circumstances. It isn't planned for usage on a wildfire, for example, one which has arrived at the roof, jeopardizes the client (i.e., no way out of course, smoke, blast danger, and so forth), or in any case wants the skill of a fire detachment.

Complete step by step answer:
We need to know that a fire extinguisher consists of a hand-held round and hollow weight vessel containing a specialist that can be released to stifle a fire. Fire extinguishers fabricated with non-round and hollow weight vessels likewise exist however are more uncommon.
Fire extinguishers contain various synthetic compounds, contingent upon the application. Handheld extinguishers, which are ordinarily sold at home improvement shops for use in the kitchen or carport, are pressurized with nitrogen or carbon dioxide \[\left( {C{O_2}} \right)\] to impel a surge of fire-suppressing specialist to the fire. The dynamic material might be a powder, for example, potassium bicarbonate \[\left( {KHC{O_3}} \right)\] , fluid water, a vanishing fluorocarbon or the moving specialist itself. The best and basic fluorocarbon utilized as of not long ago for this application had been bromochlorodifluoromethane \[(C{F_2}ClBr)\] , alluded to as halon \[1211\].
Carbon tetrachloride extinguisher was the fire explosive. This consisted of a glass circle loaded up with $CC{l_4}$ that was planned to be flung at the base of a fire (mid ones utilized salt-water, however $CC{l_4}$ was more compelling). Carbon tetrachloride was reasonable for fluid and electrical flames and the quenchers were fitted to engine vehicles. Carbon tetrachloride extinguishers were removed during the \[1950s\] due to the substance's harmfulness - presentation to high fixations harms the sensory system and inside organs. Moreover, when utilized on a discharge, the warmth can change $CC{l_4}$ over to phosgene gas, once utilized as a compound weapon. In a fire extinguisher, $CC{l_4}$ is used.

So, the correct answer is Option C.

Note: We must have to know that dry compound is a powder-based specialist that stifles by isolating the four pieces of the fire tetrahedron. It forestalls the substance responses including warmth, fuel, and oxygen (burning), in this manner smothering the fire. During burning, the fuel separates into free extremists, which are exceptionally responsive pieces of particles that respond with oxygen. The substances in dry synthetic dousers can stop this cycle.
