The incident occured when a resident incorrectly applied the restricted use pesticide Weevil-Cide (pellets), containing aluminum phosphide under the house to address a pest problem. The application created strong odors in the house and the resident attempted to wash the material away. Aluminum phosphide when mixed with water creates phosphine gas which is toxic and can ignite spontaneously in air. TCEQ notified EPA of the incident and requested assistance. OSC Enders and START mobilized to the site on January 2, 2017.
