Definition:
A "fire brigade" is a group of people who are trained and equipped to put out fires. In British English, it is often used to refer to the official organization, similar to what is called a "fire department" in American English.
In a more advanced context, you might refer to the specific roles within a fire brigade, such as "firefighter," "fire chief," or "fire engine," which are important for understanding the structure of the organization.
In some contexts, "fire brigade" can also refer to a group of people temporarily organized to address a specific problem, not necessarily related to fires. For example, "We need a fire brigade to fix this problem before it gets worse."
The "fire brigade" is an essential service that helps protect communities from the dangers of fire.
