Aluminium phosphide (AlP) poisoning is one of the most common causes of death in Iran. It is available in 3-gm tablet forms (Phostoxin, Celphos, Quickphos, and Phostek) known as "rice tablet" in Iran . AlP is converted to phosphine gas (PH₃) following contact with hydrochloric acid in the stomach and water or moisture. PH₃ is a highly toxic and flammable gas . It is odourless in its pure form; however some reagents such as ammonium carbamate, ammonium bicarbonate, methanethiol (methylmercaptane), urea, and paraffin are added to AlP tablets to regulate flammability and produce warning against phosphine dispersion in air . Phosphine and air mixture may ignite spontaneously and cause health hazards such as burns in poisoned patients
