In all cases qualified forklift instructors must be registered with at least one of the voluntary training organisations. Although RTITB operators are registered on a database which has to be a 3 yearly basis, the amount of time determined between refresher courses is subject to the H&S Executive, Insurance companies or company policies. The H&S Executive (HSG136 Workplace Transport Safety) does recommend re-training/testing every 3 to 5 years.
