What could happen if a fire extinguisher is charged with the wrong agent?

When a fire extinguisher is charged with the incorrect agent, it may become ineffective in dealing with the type of fire it was designed to combat. Each fire-extinguishing agent is specifically formulated to target certain classes of fire. For instance, a foam extinguisher is effective for combating flammable liquids, while a dry chemical extinguisher is suitable for electrical and combustible material fires. If a different agent is used, it may not extinguish the fire effectively, potentially leading to a dangerous situation where the fire continues to spread and cause harm.

Additionally, certain agents may react adversely with the materials involved in some fires, potentially exacerbating the situation rather than controlling it. Therefore, selecting the right extinguishing agent is crucial for ensuring safety and effectiveness during a fire emergency.
