Photographs
Another method of documentation is probably the most important and least known. That involves photographs. Carrying a small camera with you in your gear is a minor inconvenience, which at a later date, may prove your smartest idea. In the legal forum a picture is surely worth a thousand words. Nothing better conveys the message or the proof of a wrongful act than the photograph.
Such photography is to be regulated and not done so as to infringe on company secrets. Use discretion. There is no law whatsoever prohibiting your documenting with photography an unsafe condition or practice. Your film and camera are your personal property. As with your personal and medical logs, secure the film or photographs in a safe place.
