A glass fire extinguisher is primarily used for what type of fires?

A glass fire extinguisher, also known as a class K extinguisher, is specifically designed for combating fires that involve cooking oils and greases, which are commonly found in commercial kitchens. These types of fires can be particularly challenging to extinguish with traditional methods due to the high temperatures and flammability of cooking oils.

Class K extinguishers work by using a wet chemical agent that reacts with the oil to create a soap-like substance, effectively cooling and suffocating the fire while preventing re-ignition. This makes them the appropriate choice for any scenario involving fats and oils, such as those found in fryers or grills.

In contrast, other types of fires, such as electrical fires, wood fires, or metal fires, require different fire suppression agents and techniques that are more suitable for their unique combustion processes. This specificity is crucial for ensuring the safety and effectiveness of firefighting efforts in commercial environments, where diverse fire risks are present.
