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

Fumigant formulations include warning agents primarily to provide a safety alert. These agents are incorporated to ensure that anyone in the vicinity can detect the presence of the fumigant, which may be hazardous. Fumigants can have dangerous or toxic properties, and their use typically involves confined areas where awareness of exposure risks is crucial. By including a warning agent, fumigation practitioners help minimize the risk of accidental inhalation or exposure, allowing workers and nearby individuals to take appropriate safety measures if they detect the agent's odor.

In this context, the warning agents serve a critical role in safety protocols, as their discernible smell can prompt immediate action to evacuate or ventilate the area as needed. This is particularly important in fumigation scenarios, where toxic exposure can have severe health implications.
