Child-resistant locks in poison control

Three child-resistant locks were incorporated into a medicine cabinet, an under-the-sink cabinet, and a vanity box. Three hundred 3- to 5-year-old children were tested against these locks. Only two were able to open the receptacles, whereas all 50 of a group of adults and teenagers similarly tested were able to open all of the containers. The use of adequately protected medicine chests and under-the-sink cabinets is urged as a further step toward the complete prevention of poisoning in children.
