Which of the following is a suggested strategy to prevent firearm accidents?

Installing safety devices on guns is a highly effective strategy to prevent firearm accidents. Safety devices, such as trigger locks or gun safes, help to ensure that firearms cannot be discharged unintentionally, especially by children or unauthorized users. By making it more difficult to access the gun without proper knowledge or intent, these devices act as a vital barrier against accidental discharges.

While educating everyone about gun laws is important for responsible gun ownership, it does not directly prevent accidents. Similarly, ensuring guns are locked away from view might reduce the likelihood of curiosity-driven access, but it does not address accidental usage if the guns are still accessible in critical moments. Keeping guns in a trusted neighbor's house could theoretically add an extra layer of security, but it also introduces the risk of someone else mishandling the firearm. In contrast, using safety devices directly mitigates the chance of accidents related to firearm handling and storage.
