Although OSHA has not put a number on this, it is definitely a good idea for your forklift trainers to have a refresher course every so often. How often that is, though, is up to you. Times inevitably change and if a trainer spends too long without attending a class he or she may miss out on important updates or changes to the curriculum. Keep in mind that a trainer who trains regularly is more likely to have the information fresh in their mind than one who only gets to train sporadically. Take that into account when determining when your trainer should be retrained. In between trainings, trainers should keep an eye out for changes and read the forklift standard at least once a year to keep on top of things.
