Rule #2 from the Rules for Kids is:

The principle of "Don't touch" emphasizes the importance of safety when it comes to firearms, particularly for children. This rule is fundamental because it encourages individuals, especially kids, to refrain from interacting with a firearm unless they are trained and supervised by a responsible adult. The idea behind this guideline is to prevent accidental discharges or injuries that may arise from untrained handling of a weapon.

This rule serves as a crucial first step in firearm safety, instilling an understanding of the inherent dangers associated with firearms. By teaching children to avoid touching firearms unless instructed otherwise, it fosters an environment of caution and respect for these powerful tools. The other options may convey different safety messages but do not carry the same foundational priority as the immediate directive to "Don't touch."
