What is the primary reason for fumigant formulations to include warning agents?

The primary reason for fumigant formulations to include warning agents is to provide a safety alert. Warning agents are specifically added to fumigants because many of these chemicals are odorless or have very low detectable odors, which can pose significant risks to human health and safety if inhaled unintentionally. By including a warning agent that emits a strong, detectable odor, users and individuals in the vicinity can be alerted to the presence of the fumigant before it reaches hazardous levels. This serves as an essential safety measure to prevent accidental exposure and ensure that appropriate precautions can be taken. The effectiveness of the fumigant is not related to these agents, nor do they serve to mask odors or decrease toxicity; rather, their primary function is to function as a safety mechanism.
