What is the method of fire suppression referred to as Direct Attack?

The method of fire suppression known as Direct Attack involves applying water directly to the base of a fire using a solid stream. This approach is effective because it targets the source of the flames, allowing for immediate cooling of the burning materials and reducing the potential for fire spread. By impacting the fire where it is most vigorous, firefighters can achieve rapid extinguishment and better control of the situation.

Applying water in a solid stream allows for penetration into the fire, which is crucial for extinguishing the heat and interrupting the combustion process at its origin. This method is particularly useful in situations where firefighters can get close to the fire source without risking safety.

Other methods, such as bouncing water off walls or ceilings, rely more on indirect techniques that can take longer to suppress a fire. Utilizing steam as a means of suppressing fire also tends to be more about managing hot gases and cooling down the environment rather than directly extinguishing the flame. Finally, applying water only after ventilation is complete emphasizes a different tactic aimed at controlling smoke and heat but doesn't effectively address the immediate suppression of the fire itself.
