Portable fire sprays, also known as fire extinguishing sprays or aerosol fire extinguishers, are an accessible and straightforward option for addressing small fires quickly. They are an excellent addition to home safety protocols, vehicle safety kits, or for use during outdoor activities.
There are several types of portable fire sprays available, each designed for different types of fires:
These sprays contain a dry chemical powder, usually monoammonium phosphate (ABC powder), effective against Class A, B, and C fires. They extinguish fires by disrupting the chemical reaction of the fire triangle.
Ideal choices for ordinary combustibles
Primarily used for Class A fires, these sprays cool the burning material and separate the fuel from oxygen. Some are also formulated to combat Class F fires with additives that create a cooling foam barrier.
Suitable for Class A and B fires, foam sprays form a barrier over the flames, depriving them of oxygen and preventing re-ignition. They are typically used for fires involving liquids like gasoline.
Although less common in spray form, CO2 extinguishers are effective against Class B and C fires, working by displacing oxygen and cooling the fuel.
These are formulated for Class K fires, particularly those involving cooking oils and fats. The chemicals react with the oil to create a soap-like substance, sealing the fire.
The latest addition to the market, these sprays use environmentally friendly, non-toxic, and biodegradable agents to extinguish fires, making them safe for use around humans, animals, and plants.
When selecting a portable fire spray, you must consider the specific fire risks in your environment. A kitchen might benefit from a wet chemical or water-based spray, while a dry powder or foam spray might be better for a car or garage. Ensure that the product meets the safety standards and certifications for your region or country.
