Which of the following settings commonly uses Type B extinguishers?

Type B extinguishers are specifically designed to combat fires that involve flammable liquids and gases, such as oil, gasoline, and solvents. These types of fires are more likely to occur in environments where such materials are present, which is common in kitchens—particularly in commercial settings where cooking oils are used—and laboratories where chemicals and flammable substances are handled.

Kitchens and laboratories are both environments that often harbor these flammable substances, making Type B extinguishers essential for ensuring safety in these locations. Understanding the importance of Type B extinguishers in these settings highlights the need for proper fire safety measures and preparedness where these types of materials are used or stored.

In other environments like residential homes, office buildings, or outdoor camping sites, fires can occur, but the specific risks and types of flammable materials present are different and may require other classes of extinguishers. For instance, residential homes may deal more with Class A fires (ordinary combustibles) and sometimes Class K fires (cooking oils), while office buildings focus mainly on electrical fires and paper (Class A). In outdoor camping, the risk typically involves natural elements and possibly Class A materials such as wood, rather than the flammable liquids targeted by Type B extinguishers. Understanding
