The LEGO DUPLO Fire sets, released across various years, introduce young children to firefighting and emergency response scenarios. Notable sets include "Fire Station" (10593) from 2015, featuring a fire station building, fire truck, and multiple firefighter figures; "Fire Station" (6168) from 2009, which includes a fire station, fire truck, helicopter, and accessories for various rescue missions; and "Fire Truck" (10592) from 2015, which includes a fire truck with a ladder, firefighter figure, and accessories like a fire hose and a buildable flame. These sets aim to develop fine motor skills and encourage imaginative play through heroic firefighting adventures.
The LEGO DUPLO theme is designed for children ages 1 to 5. It features DUPLO figures which are much larger than minifigures and DUPLO blocks which are about twice the length, width, and height of a standard System brick.
