In Canada, lightning flashes occur about 2.34 million times a year; with the highest levels of concentration during the summer months.

While most lightning on earth is ground-to-cloud,  recent research has identified that the majority of lightning events to tall structures, such as wind turbines, occur in the presents of ground-to-cloud leaders – upward lightning.  More importantly, the majority of ground-to-cloud leaders transpire following a sudden change in electric field initiated by either cloud-to-cloud, cloud-to-air or cloud-to-ground discharges.

Since the late 1990’s, the utility grade wind turbine sector has identified lightening events as a significant risk factor.  Today, many standards...

Remote field operations present the safety organization with a myriad of challenges when it comes to ensuring the safety of the people that you send out to work in the field every day. Without a doubt, this includes the line workers, but it also includes nearly every member of the staff whose duties are performed outside of the controlled confines of your facilities. Certainly, many of the hazards are identifiable and risk mitigation procedures and equipment are deployed, along with your remote crews, in the effort to keep everyone safe and bring them back home at the end of the...
