What defines a child-resistant container according to regulations?

A child-resistant container is defined by regulations to ensure it is difficult for young children to access potentially harmful substances, while still being usable by adults. The correct definition states that the container cannot be opened by 80% of children under the age of 5, which helps to protect this vulnerable population from accidental poisoning or harm. At the same time, the design allows for it to be opened by at least 90% of adults, ensuring that the container remains practical for the intended users.

This balance is crucial in pharmaceutical and toxic substance packaging to promote safety and accessibility. The need for child resistance is underscored by statistics showing that a significant percentage of young children can open containers that do not meet these stringent standards.

The incorrect options either do not meet the regulatory requirements for child resistance or suggest a lack of necessary design features. For instance, stating that a container can be opened by children as easily as adults contradicts the very essence of what makes a container child-resistant. Similarly, the absence of design features or transparency requirements does not comply with the safety measures mandated by regulations aimed at protecting children.
