This Old House has a grisly gallery of x-rays from nail gun accidents as well as some helpful tips for, you know, not seriously injuring yourself with a nail gun. The combination of the images and the tips… very effective. Ow, ow, ow, ow…
The first tip will sound familiar to those of you who know anything about real gun safety:
Take your finger off the trigger immediately after you’ve driven in a fastener. And never carry the nail gun with your finger cocked to shoot.
This is good advice.
