3 TESTS ON OUR SAFETY EQUIPMENT Our safety equipment has been approved in practice and allows for a safe working in electrical systems. It complies with the approved engineering rules as well as with the national rules for the prevention of accidents and exceeds the requirements of international and national standards. The high quality and reliability of our safety equipment is ensured by a number of process inspections. The following pictures show some tye tests on our safety equipment.
