Before disposing of liquid pesticide containers, what is the first step in the triple-rinsing procedure?

The correct first step in the triple-rinsing procedure for disposing of liquid pesticide containers is to fill the container with water. This step is crucial because it helps to dilute any residual pesticide that may remain in the container. By adding water, you facilitate the rinsing process, allowing any pesticide left inside the container to mix with the water, making it easier to remove.

The next steps would typically involve shaking or agitating the container to ensure that all interior surfaces are reached and rinsed effectively. It is important to follow this procedure to minimize environmental contamination and comply with safety regulations for pesticide disposal. The correct approach ensures that the pesticide does not enter the environment in concentrated forms, thereby protecting ecosystems and human health.

The other options do not correctly initiate the proper procedure. Simply shaking the container or leaving it untouched does not effectively clean it, while dumping any residual liquid into a field is unsafe and potentially harmful to the environment.
