Minnesota Pesticide Applicator Practice Test

The statement that water jets should never be used to put out a pesticide fire is true. This is primarily due to the nature of many pesticides, which can react negatively with water and potentially create harmful situations. When water is applied to certain types of pesticides that are flammable or otherwise hazardous, it can lead to the spread of the fire, create toxic vapors, or even result in chemical reactions that could further intensify the situation.

Additionally, fire-fighting procedures for chemical fires often involve specific agents that are designed to suffocate flames or disrupt the combustion process without reacting negatively with the burning substances. This is why using water jets is typically not an advisable method in such scenarios, as it might exacerbate the fire rather than extinguish it. Understanding the chemical properties of the materials involved is crucial for safe response in fire situations, particularly with pesticides.
