Posted By Paul Adams Our trainer recommends every 3 years or following an accident or prolongued absence, or whenever you believe the operators standards are slipping. We accept the trainer's advise on this issue and adopt it as best practice. The question you should ask yourself with regard to documented refresher training: - If one of your flt operators is involved in an accident, how will you prove, in court, that you have ensured that operator is competent to use that work equipment?
