<h3>What is fire department?</h3>
An organization that performs fire prevention, fire suppression, rescue, and hazardous materials mitigation is known as a fire department or fire brigade, often referred to as a fire authority, fire district, fire and rescue, or fire service in some locales.
The Department's personnel have received all-hazards emergency response training. Fire suppression, emergency medical response, hazardous materials response, fire prevention, and education are the Department's primary duties.
A fire department may have one or more fire stations within its borders. These stations may be manned by professional, volunteer, conscript, or on-call firemen. Volunteer and professional firefighters are mixed together in combination fire departments.
