Renewal timing catches more people out than the initial course itself. UETDRRF018 runs on a three year cycle, while CPR usually runs on a twelve month cycle, so the two dates drift apart unless they are reset together. Turning up to a job with an expired ticket is treated the same as having no certification at all, and that can mean lost site access and lost income. Keeping a Low Voltage Rescue Course current protects more than a certificate on the wall. It protects the people working alongside you.
