The vast majority of household products are not hazardous when swallowed in small amounts. However, certain products such as bleach become hazardous when swallowed in large amounts. The case of a 65-year-old female who drank a cup of bleach is presented. She died 3 days after admission to hospital of bilateral basal bronchopneumonia, a complication of chlorine gas, which was caused by the reaction of gastric acid & bleach. Concentrated acid & alkali solutions are dangerous even in small amounts.
