What is the primary focus when assessing the potential hazard of a pesticide?

The primary focus when assessing the potential hazard of a pesticide revolves around understanding the conditions of exposure and toxicity. This is crucial because it allows handlers to evaluate how the pesticide interacts with various elements in its environment, including humans, wildlife, and beneficial organisms.

By analyzing the toxicity of the pesticide along with the specific conditions under which exposure might occur—such as application methods, weather conditions, and the proximity to habitats or sensitive areas—handlers can make informed decisions. This assessment is vital for determining the risks associated with the pesticide use and is key to implementing safety measures to protect oneself and the environment.

In contrast, while financial costs, environmental impacts, and availability are important considerations in the overall decision-making process regarding pesticide use, they do not directly address human health and ecological safety in the same manner as exposure and toxicity. Thus, they take a secondary role when evaluating the potential hazards of a pesticide.
