Pipe Markers | Pipe Marker Applications | European Pipe Marking
Pipes that are visible and containing dangerous substances must be labeled in accordance with the directive 67/548/EEC.
The Directive 67/548/EEC is the directive regarding the regulations for the labeling, classification, and packaging of dangerous substances.
Safety signs must be placed where hazards cannot be avoided or reduced by preventive measures. Labels used on pipes must be visible in the most dangerous points, such as valves and joints and at reasonable intervals. The dimensions of the pipe markers must be proportionate to the labeling surface. Learn more about the proportions and other label requirements from this free pipe marking guide.
