Fire extinguishers are active fire protection equipment, essential to prevent small fires from turning into major catastrophes. Although they are not intended to combat large-scale fires, they are effective in preventing an initial fire from spreading.

History of Fire Extinguishers

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

Types of Fire Extinguishers and Their Applications

The choice of the appropriate extinguisher should be based on the specific risk of the location and the type of combustible material present. Each fire class requires a specific type of extinguisher:

CLASS A

• Water-based extinguishers

CLASS F

Safety in the Use of Extinguishers

Remember that extinguishers have a limited charge and can run out in seconds. Therefore, it is essential to know how to use them correctly. If in doubt, it is recommended to take specific training courses on the use of fire extinguishers.
