Fire Extinguisher: Origin, Evolution and Importance

The fire extinguisher is one of the most essential pieces of equipment for preventing and fighting fires . From its invention to modern models, this device has evolved to ensure greater safety in homes, businesses and industries. In this article, we explore the history of the fire extinguisher, the types that exist and their importance in fire safety.

Origin and Invention of the Fire Extinguisher

The first model of fire extinguisher was patented in 1723 by the English chemist Ambrose Godfrey . It was a barrel of water with gunpowder, which when exploded spread the liquid over the fire.

However, the first modern portable fire extinguisher appeared in 1818, created by the English captain George William Manby . Called Extincteur , it consisted of a copper cylinder containing water and potassium carbonate, expelled through compressed air. This model served as the basis for modern fire extinguishers , becoming a milestone in the history of fire safety .

Evolution of Fire Extinguishers: New Extinguishing Agents

In the 20th century, new types of extinguishers emerged, each designed to combat different classes of fires :

• 1905 – Chemical foam extinguisher: Ideal for flammable liquids.
• 1924 – Carbon dioxide (CO₂) extinguisher: Safe for electrical equipment as it does not conduct electricity and leaves no residue.
• 1950s – Dry chemical extinguisher: Versatile, suitable for various types of fires.
• 1960s – Halon extinguisher: Very effective, but now restricted due to environmental impact.

Types of Fire Extinguishers and Their Applications

Modern fire extinguishers are classified according to the type of fire they fight. Knowing the types is essential to ensure the correct choice:

• Water Extinguisher: Suitable for fires in solid materials such as wood, paper and fabrics.
• CO₂ (Carbon Dioxide) extinguisher: Recommended for electrical equipment as it leaves no residue.
• Dry Chemical Extinguisher: Effective against fires in flammable liquids and combustible gases.
• Foam Extinguisher: Used on oil and liquid fuel fires.

Importance of Fire Extinguishers in Fire Prevention

Using a fire extinguisher correctly can prevent major disasters and save lives. To do this, it is essential to:

• Keep fire extinguishers in accessible and signposted locations.
• Perform regular inspections and periodic maintenance.
• Ensure that employees know how to use the equipment correctly.

Furthermore, safety legislation requires the presence of fire extinguishers in companies, public buildings and commercial spaces, ensuring a safer environment.

Conclusion

The history of the fire extinguisher shows how this piece of equipment has evolved to become a fundamental part of fire safety . Today, there are several models suitable for different types of fire, and their correct use can be the key to avoiding tragedies.

If you want to ensure the safety of your space, make sure you choose the right type of fire extinguisher and keep up with maintenance. Prevention is always the best strategy!
