What does the Poison Prevention Act of 1970 require concerning substances that could harm children?

The Poison Prevention Act of 1970 was enacted to protect children from accidental poisonings caused by hazardous substances. The key requirement of this act is that certain substances, particularly those that are toxic or harmful if ingested, must be packaged in child-resistant containers. This means that for medications and household products that pose a significant risk to children, the packaging must meet specific standards to make it difficult for young children to open, thereby reducing the chances of accidental ingestion and potential harm.

This legislation recognizes that many injuries and fatalities in children are preventable through simple measures like ensuring that dangerous substances are less accessible. The focus on child-resistant packaging has been a pivotal aspect of reducing the incidence of poisoning in young children, making it a primary reason why option B is the correct answer.
