What is a common mistake regarding pesticide storage facility fires?

Extinguishing a fire in a pesticide storage facility with water is a common mistake because water can react negatively with certain chemicals found in pesticides, potentially causing dangerous reactions or spreading the fire. Instead of effectively putting out the fire, using water may create more hazardous situations, including chemical spills or toxic vapors that can arise when water interacts with flammable or reactive substances.

In contrast to this common error, the best practices include using foam extinguishers, which can smother the fire and prevent it from spreading without the adverse reactions that water might provoke. Allowing a fire to burn out may seem like a viable option, but it can lead to uncontrolled burning and further risks to nearby structures and the environment. It's also essential to call the fire department immediately so that trained professionals can handle the situation appropriately, minimizing harm to people and the environment.
