Which type of pesticide formulation is more likely to cause an explosion?

Total-release aerosol formulations are more likely to cause an explosion due to the pressurized containers in which they are stored and dispensed. These aerosol products contain volatile propellants that can build up significant pressure, making them susceptible to exploding if exposed to heat or punctured. Additionally, when aerosol products are released, they disperse as fine mist or spray, which increases the likelihood of ignition in the presence of open flames or sparks. This characteristic of total-release aerosols underscores the necessary precautions that must be taken when handling and storing such products, particularly in environments where heat sources or flammable materials are present.
