The risk-oriented approach to industrial safety allows for the operation of hazardous production facilities in the cracks presence. There is a problem of assessing the critical size of cracks by non-destructive methods, which are currently not widely tested and standardized. Changing operating conditions and damage accumulation can transfer cracks into the category of developing cracks, and this can lead to catastrophic consequences. From this point of view, close proximity of objects containing explosive substances, as it is the case at processing plants, pumping stations, production platforms, poses a danger. Visualization of hazardous objects and their location areas warns the personnel about the need to comply with increased safety measures. This is aimed at using industrial design, which defines the principles of warning of hazardous objects by using color signs. A common trend in the coating usage is their multifunctionality. In this regard, the present research attempts to combine color warning signs with the possibility of their usage in composite coatings designed for corrosion protection, as well as showing the changes in temperature conditions of processes.
