**5. Heat-protective fence design**

To assess the effectiveness of various technical solutions for the fence, the following samples were made (**Table 5**).

• Sample 1 is a typical fragment of the thermal insulation of refrigerated wagons and containers. It consists of a steel sheet with a thickness of 2 mm, a U-shaped frame with dimensions of 30 30 2 mm, expanded polystyrene with a thickness of 60 mm, an inner lining of plywood with a thickness of 4 mm, an aluminum sheet with a thickness of 2 mm;
