Which pesticide formulation poses a danger if its container is punctured or overheated?

Aerosol formulations are particularly hazardous if their containers are punctured or overheated due to the pressurized nature of their packaging. These formulations contain liquid pesticides that are maintained under pressure which allows them to be sprayed in a fine mist. If the container is compromised, for example, by puncturing or exposure to excessive heat, it can lead to a rapid release of the contents, potentially resulting in a dangerous spray that can harm humans or the environment.

In contrast, dust formulations, liquid pesticides, and granules do not have the same level of risk associated with pressure. Dust formulations can disperse easily but do not pose an explosion risk; liquids can spill but do not have pressurized containers; granules are solid and not likely to react dangerously under physical stress. Therefore, the properties of aerosol containers make them particularly risky compared to the other pesticide formulations listed.
