What does the signal word on a pesticide label indicate?

The signal word on a pesticide label serves as a vital guide to understanding the degree of hazard associated with the product. It provides a quick reference for users to assess the potential risks involved in handling and applying the pesticide. Signal words are typically classified into categories like "Caution," "Warning," and "Danger," each indicating different levels of toxicity and potential harm. This helps users to make informed decisions about safety measures, personal protective equipment, and overall handling procedures.

The other choices do not accurately describe the purpose of the signal word. The concentration of the pesticide concerns the amount of active ingredient present and is typically noted elsewhere on the label. The shape of the hazard symbol may provide some information about the type of hazard, but it does not directly communicate the degree of hazard as effectively as the signal word. Lastly, the manufacturer of the pesticide is listed on the label, but this information does not relate to the risk level of the pesticide itself. The signal word is specifically intended to alert users to the level of danger they may encounter while using the product.
