What is the most effective way to extinguish small Alpha fires?

The most effective way to extinguish small Alpha fires is by using CO2 extinguishers. Alpha fires typically involve solid materials, such as wood, paper, and textiles. CO2 extinguishers work by displacing oxygen in the area where the fire is burning. This suffocation method is particularly effective for small fires because it quickly reduces the available oxygen and interrupts the combustion process.

Additionally, CO2 does not leave any residue, making it safe to use on sensitive equipment or in situations where other extinguishing agents might cause contamination or damage. While other methods such as water spray can be effective for cooling and suppressing fires, they may not be as suitable in all environments due to risks of spreading flames, especially if there's a risk of the fire involving electrical materials. Foam extinguishers are more appropriate for flammable liquid fires (Class B fires), and fire blankets are typically used to smother flames on a person or to cover small fires in a controlled manner, rather than for extinguishing larger Alpha fires effectively.
