Substances that are dangerous even in small amounts include petroleum products/hydrocarbon in the respiratory tract, substances used as alcohol substitutes, highly corrosive substances and some adult medicines. A poisoning event with a happy ending will offer an opportunity to advise the parents about future preventive measures. All dangerous household substances must be stored out of the reach of children. Keeping medicated charcoal at home will hasten the onset of treatment by at least 15–30 minutes, which may prove to be significant as far as symptom development and prognosis are concerned.
