Fire extinguishers are active fire protection equipment that are essential to prevent small fires from becoming major disasters. Although they are not intended to fight large fires, they are effective in preventing an initial fire from spreading.

The first records of fire extinguishers date back to 1723. Since then, they have evolved to become essential in fire protection, providing a first line of defense in emergency situations.
