There were also two firefighters who were taken to the hospital. Con Fire said the four are expected to be OK.
Organophosphorus is a compound that can be used in fertilizers, pesticides and herbicides, and exposure can cause the nervous system to stop working properly, according to the Centers for Disease Control and Prevention.
