Insulating stakes to prevent electrocution

Metal stakes that are used as markers or to cordon off a specific area at worksites can sometimes strike and breach an underground electrical cable (which can conduct up to 20,000 volts). This represents a major risk for employees assigned to the task of installing the stakes. The division in Basse-Normandie worked closely with a plastics expert to design an insulating plastic and fibreglass stake with a metal end with a protective capacity of up to 100,000 volts. The new stakes are lighter and more flexible and feature higher-resistance heads. At first, the new stakes were used at Company worksites; in the medium term, their use will be extended to other settings.

This tool was awarded a Materials Prize in the Materials and Tools category.
