Which of the following is NOT a product that typically requires child-resistant packaging?

Child-resistant packaging is designed to prevent children from accessing potentially harmful substances. Certain products are mandated by regulatory guidelines, such as the Poison Prevention Packaging Act, to be provided in child-resistant containers due to their risk of poisoning or harm if ingested by children.

Throat lozenges, insulin, and petroleum distillates are substances that are typically considered to pose significant risks to children. Throat lozenges may contain active ingredients that, in large quantities, can lead to adverse effects. Insulin, a critical medication for those with diabetes, can be life-threatening if ingested by a child. Petroleum distillates are toxic if swallowed, which further mandates their inclusion in child-resistant packaging.

On the other hand, calcium supplements, while they should be taken as directed, typically do not have the same level of toxicity or risk of harm in a child if ingested, especially when compared to the other products listed. Therefore, they are not typically required to be in child-resistant packaging, making them the correct choice for the question of what product does not generally necessitate such packaging.
