many countries have passed safety standards limiting the types of toys that can be sold. most of these seek to limit potential hazards, such as choking or fire hazards that could cause injury. children, especially very small ones, often put toys into their mouths, so the materials used to make a toy are regulated to prevent poisoning. materials are also regulated to prevent fire hazards. children have not yet learned to judge what is safe and what is dangerous, and parents do not always think of all possible situations, so such warnings and regulations are important on toys.
