What is EN ISO 20471 & RIS-3279?

Posted by Helen Wood on behalf of Pressure Pump Solutions Ltd on 15th Nov 2021

EN ISO 20471 is an international standard that requires personnel in high-risk situations to wear visible clothing. Using the proper safety gear is critical and must be prioritised. Even if working in places where visibility is critical only takes up a small part of the working day.


RIS-3279-TOM (previously GO-RT 3279) is a high visibility standard that exclusively applies to the rail industry in the United Kingdom, as contrast to other EN standards that apply to the entire EU. The goal is to make rail personnel on or near the trackside visible to trains approaching at high speeds or other traffic.
