Their low volatility
Their ability to create a fog
The possibility of single large exposure

The correct answer is: The possibility of single large exposure

The common feature of fumigants that leads to potential poisoning is their potential for a single large exposure. Fumigants are designed to be effective in very small concentrations, and they are often used in enclosed spaces. This use can create scenarios where a person is inadvertently exposed to a high concentration of the substance at once, especially if proper safety protocols are not followed. Single large exposures can overwhelm the body's ability to detoxify the chemical, leading to acute poisoning. Therefore, understanding the risks associated with high concentration exposure is crucial for those working with fumigants. In contrast, the other options highlight characteristics of fumigants but do not directly account for the immediate risk of toxic effects associated with exposure levels.
