Which of the following describes the two methods to attack a fire?

• A. Direct (aim right at the flames) and Indirect (air around the flames)
• B. Direct (aim at the flames) only
• C. Indirect (air around the flames) only
• D. Ventilation and cooling

Answer: (A)

The essential idea is that there are two established ways to attack a fire with water: a direct attack and an indirect attack. A direct attack means directing the water straight onto the flames to rapidly cool the burning fuel and stop the flame at its source. This is usually the quickest and simplest method when you can safely reach the fire. An indirect attack uses water in a fog pattern around and surrounding the fire rather than hitting the flames head-on. This cools the surrounding air and hot gases, lowers the heat load, and can displace or dilute the heat and oxygen around the fire, making it easier to control and approach. It’s especially useful when direct entry would be hazardous or when dealing with large or compartmentalized fires. So the option that includes both direct (aim at the flames) and indirect (air around the flames) captures these two fundamental methods.
