Final answer:
The Poison Prevention Packaging Act mandates that at least 85% of children under 5 years old cannot open the packaging within 5 minutes and at least 90% of adults can open and properly re-secure it.
Step-by-step explanation:
Under the Poison Prevention Packaging Act (PPPA), packaging must be designed in such a way that a significant percentage of children under the age of 5 cannot open the packaging within a reasonable time and that a certain percentage of adults can open and properly re-secure the package. Specifically, the PPPA requires that packaging must be designed to ensure that no less than 85% of children tested, who are less than 5 years of age, cannot open the package within 5 minutes. Furthermore, the law also requires that the packaging be accessible to adults, stipulating that at least 90% of adults, without assistance or demonstration, must be able to open and properly re-secure the package within a reasonable time. These regulations are intended to minimize the risk of accidental poisoning in children while still allowing adults access to the contents.
