Intra-cardiac nail

Q: What parts of the body are most commonly affected in nail gun injuries? show answer

A: Hands and feet are most common.

Q: What safety feature present on most guns prevents the un-modified tool from being used as a projectile weapon? show answer

A: The most common firing mechanism is the dual-action contact-trip trigger, which requires that the manual trigger and nose contact element both be depressed for a nail to be discharged. The sequential-trip trigger, which is safer, requires the nose contact to be depressed before the manual trigger, rather than simultaneously with the trigger. Approximately 65% to 69% of injuries from contact-trip tools could be prevented through the use of a sequential-trip trigger, according to the CDC (from reference 1-2).
