Think about this: if you go to court or give a deposition will you be able to defend your training? If you follow OSHA 1910.178, ANSI/ITSDF B56.1, PAL, CALOSH, MIOSH, and as many safety organizations and forklift manufacturer's training recommendations as you can find then you will be able to defend yourself and your employer. Training should consist of formal instruction such as classroom instruction, written materials, videos, exams, discussions, hands-on including pre-shift inspection and driving skills evaluation, etc. The more you document what you do the better. Yes you can surf the internet about how to drive a forklift but you may kill yourself or someone else without the proper training. Just like you can read about how to swim but you may drown when you jump in the lake.
