How long does a GWO certification last?

At Tech Safety Lines, we help our clients meet the latest safety and training standards for their industry. We monitor changes to the standards, manage our student’s training certifications, and notify them when it is time for renewal. Employers can always contact TSL to enquire about an employee’s training status.

Here in the U.S, we are seeing many wind industry leaders adopt the Global Wind Organization (GWO) training standards. The goal of GWO is to streamline the training quality and validity of those working in wind power worldwide.

Tech Safety Lines offers the majority of the GWO curriculum at our state-of-the-art 40,000 sq. ft. training facilities in Dallas, TX. Students can be certified for Basic Safety Training, Advanced Rescue Training, Enhanced First Aid, Basic Technical Training, Control of Hazardous Energies, Slinger Signaler, and Blade Repair, as well as refresher courses.

Individuals maintain their GWO certifications via WINDA, the global database designed for verifying a person’s training status. It allows the certification to be portable and recognized both locally and internationally.

It is important to note that GWO requires wind technicians complete their recertification for the varying modules prior to the expiration dates listed on their WINDA ID. Below we have listed the duration of a training certification for each GWO training module offered at TSL.
