Explanation:
The exploitation of high-value natural resources, including oil, gas, minerals and timber has often been cited as a key factor in triggering, escalating or sustaining violent conflicts around the globe. Furthermore, increasing competition over diminishing renewable resources, such as land and water, are on the rise.
Describe in which situation the following fire extinguishers are used: Water (Red Label), Powder (Purple Label) and Carbon Dioxide (Black Label). (150 words)
Answer:
Water fire extinguishers, labeled with a red label, are used on fires involving solid combustibles like paper, wood, and textiles. They work by drowning the fire, removing the heat required to continue burning. Powder fire extinguishers, labeled with a purple label, are more versatile as they can be used on different types of fires like those including flammable liquids, gases, and electrical equipment. Powder extinguishers work by suffocating the fire, interrupting the chain of chemical reactions involved in combustion. Carbon dioxide fire extinguishers, labeled with a black label, are used on fires involving electrical equipment and flammable liquids and gases. Carbon dioxide works by displacing the oxygen required for burning, extinguishing the fire. However, care must be taken when using carbon dioxide extinguishers in confined spaces as they may displace the breathable air, causing suffocation. It is important to note that fire extinguishers are not suitable for all types of fires, and a wrong choice of the extinguisher may worsen the situation.
