Fires that result from combustible liquids, such as kerosene, gasoline, oil and grease, are classified as Class _____.

Fires that involve combustible liquids such as kerosene, gasoline, oil, and grease are classified as Class B fires. This classification is important because it helps indicate the appropriate firefighting methods and extinguishing agents to use. Class B fires involve flammable liquids and gases, which can produce volatile vapors that make them especially dangerous. For extinguishing these types of fires, agents such as foam, carbon dioxide, or dry chemical extinguishers are typically recommended. These agents are effective because they can suppress the vapors and remove the heat, which is essential in controlling and extinguishing the fire.

In contrast, Class A fires involve ordinary combustible materials like wood, paper, and textiles, while Class C fires are electrical fires involving energized electrical equipment, and Class D fires involve combustible metals like magnesium and sodium. Understanding the classification of fires is crucial for effective fire safety and emergency response, particularly in ensuring that the correct types of extinguishing agents are used for different situations.
