Everyone deserves to go home unharmed at the end of the (working) day.
There is a risk of short circuits and arc flash when working on the electricity network. An arc flash is rare, but the consequences are disastrous. Mechanics, installers and bystanders run great risks due to the enormous explosion associated with an electric arc. Optimal protection against electric arcs is an absolute necessity.
HyTEPS offers 1-day and 2-day Arc Flash training courses (Dutch) that teach you everything about (the prevention of) arc flashes.
