How is "hazard" defined in relation to chemical exposure?

In the context of chemical exposure, "hazard" is defined as the likelihood of injury or death resulting from that exposure. This definition encompasses not only the inherent toxic properties of a chemical but also the circumstances and conditions under which exposure occurs. Understanding this relationship is essential for assessing risk, which involves considering both the hazard presented by a chemical and the potential for exposure to occur. Acknowledging this definition allows pesticide applicators to make informed decisions regarding safety measures and appropriate use of chemicals to minimize risks associated with their application.

The other choices do not accurately capture the concept of hazard as it pertains to chemical exposure. While the effectiveness of a chemical, its solubility, and methods of application are important aspects to consider, they do not convey the concept of potential harm or risk associated with exposure to that chemical. Therefore, they do not align with the definition of hazard in this context.
