What final step should you take when managing a pesticide spill?

The final step you should take when managing a pesticide spill is to notify the fire department. This is crucial because the fire department is equipped to handle hazardous material incidents, ensuring that the situation is contained and cleaned up properly. They can also help prevent any potential spread of the pesticide, especially if there is a risk of fire or if the spill threatens to contaminate water sources. Their expertise is essential in managing emergencies efficiently and safely.

Informing local authorities, calling for additional help, and posting warnings are all important steps in the response to a pesticide spill. However, the involvement of the fire department is specifically designed for hazardous materials and is essential to handle the situation appropriately.
