Which action should be taken first when cleaning up a pesticide spill?

The action to control and stop the source of a pesticide spill is critical and must be the first step taken in the cleanup process. Addressing the source of the spill minimizes the potential for further leakage or spread of the pesticide, thus reducing the risk of contamination to the environment, surrounding areas, and human health. By immediately stopping the source, you not only protect nearby individuals but also facilitate a more manageable cleanup operation.

Once the source has been controlled, other steps such as notifying emergency services, containing the spill, and calling the appropriate hotline can proceed effectively. These actions rely on the successful management of the initial spill to be truly effective, as each subsequent step will depend on the spill being contained to a certain extent. Therefore, stopping the source is foundational in the response to a pesticide spill.
