Many medications, cleaning products and chemicals have child-resistant (CR) lids to protect children. Most people call these “child-proof”. The Poison Prevention Packaging Act (PPPA) of 1970 states that in order for a product to be child-resistant, 80% of children under age five will not be able to open it within 10 minutes. Studies show that the PPPA has lowered poisonings and poisoning deaths in young children by about 40%. It is important to use CR lids because it gives a couple of extra minutes to catch a child in the act, hopefully before a poisoning happens. However, most children are able to open CR lids if given enough time. Virtually nothing is child-proof when it comes to poisonings. CR lids along with other safety measures are needed to help prevent poisonings.
