What is a recommended action to take in the event of a pesticide spill?

Constructing berms to contain contaminated runoff water is a recommended action in the event of a pesticide spill because it helps to prevent the spread of hazardous materials. Berms act as barriers that can effectively contain the spill, reducing the risk of pesticides entering nearby water sources or affecting surrounding areas. This containment is crucial for minimizing environmental impact and ensuring that the pesticide does not migrate, potentially causing harm to wildlife or ecosystems.

Other options may not provide the necessary immediate response to mitigate the spill's effects. For instance, while evacuating personnel can be a safety measure, it does not address the environmental consequences of the spill. Consulting a hospital may be necessary later for health concerns but does not aid in managing the spill itself. Pouring more pesticide over the contaminated area is not a safe or effective method for neutralization; it could exacerbate the situation and lead to greater environmental harm. Therefore, constructing berms for containment is a proactive and responsible approach to handling a pesticide spill.
