What is the correct action when aiming a H2O extinguisher?

• A. At the top of the flames
• B. At the side of the flames
• C. At the base of the fire
• D. At the nearest exit

Answer: (C)

Aiming a H2O extinguisher at the base of the fire is crucial for effective firefighting. This technique is based on the principle that fires need fuel, heat, and oxygen to continue burning. By directing the extinguisher's stream at the base, you are attacking the source of the flames directly, where the fuel is located, and where it can be deprived of the necessary heat and oxygen needed for combustion.

When you aim at the top of the flames, the water is less effective at reaching the fuel igniting the fire. Water may simply evaporate or miss the critical area where the combustible material is situated. Similarly, directing the extinguisher at the side of the flames does not adequately address the root of the fire and can result in wasted effort and resources. Aiming at the nearest exit fails to engage with the fire itself, which is not conducive to extinguishing it and could even worsen the situation by allowing the fire to spread further. Thus, targeting the base ensures that the fire is effectively suppressed at its origin.
