European Standard Pipemarkers reduce safety and aid maintenance. Pipemarkers conform to RAL European standard colour coding and for dangerous substances the Chemical Symbols conform to European Regulations 1271/2008, 790/2009 and 286/2001. Danger and hazard symbols , if relevant and necessary, are automatically printed either side of the text, and the Signal word underneath the text, this saves you having to identify the appropriate symbol. Markers are printed with a contrasting border in the same colour as the text for improved visibility. The design and layout of Brady's roll form markers ensure maximum visibility from all sides. Parts supplied with a Black arrow printed on white background.
