ProGARM for the Rail Industry | RIS-3279-TOM
What is RIS-3279-TOM?
RIS-3279-TOM (formerly known as GO-RT 3279) is a high visibility standard that only applies to the rail industry in the UK, as opposed to the EU-Wide nature of other EN standards. The aim is to ensure that rail workers on or near the trackside are sufficiently visible to trains approaching at speed or any other traffic.
High visibility clothing is the fundamental principle behind the UK Rail Industry Standard. This is based on the European Norm EN 20471:2013, and garments must comply to Class 2 High Visibility, the middle of a three class range. The standard states the following: ‘high visibility clothing worn by people on the lineside or on or near the line should conform to a single standard for the colour and luminance of background material and that this standard will accord with the detail contained within BS EN 20471:2013 high visibility clothing – Test methods and requirements (ISO 20471:2013).’
It is stated in the standard that: ‘the colour specific requirements within this standard conform to the range specified within BS EN 20471 clause 5.1.2.’ In order to confine this to a specific orange colour, and to prevent the selection of a colour at the red end of the spectrum, the precise chromaticity co-ordinates for the colour are specified as: Fluorescent orange, X:0.588, Y:0.371. with a luminance factor of at least 0.4. The accepted tolerance in colour is as laid out in EN 20471. However, there is no tolerance for the luminance factor.
Also stipulated in RIS-3279-TOM is the need of retro-reflective materials, with photometric and physical performance aligned with EN 20471.
Mentioned in RIS-3279-TOM is the accepted use of a mini vest where the nature of the work being carried out will not obscure the high visibility clothing, and thus reduce the surface area’ that is visible. The same applies to company logos; these are permitted where they do not compromise the surface area of background colour, and compensation may have to be made for this.
Arc Flash Coveralls
ProGARM 4693
Arc Flash Coveralls, from the ProGARM range of Arc Rated garments and clothing are used to protect against arc flash accidents as the last line of defence. Arc Flash PPE will not prevent incidents, and it is therefore vital that a comprehensive electrical safety plan for maintenance, repair and diagnostic procedures (involving energised LV, MV or HV electrical equipment) is also implemented.
Thorne & Derrick distribute a range of arc flash coveralls to suit a range of requirements. Variations include ladies coveralls, designs for overhead linesmen, orange and yellow hi vis options and a wide range of sizes. Contact Thorne & Derrick with your specific PPE requirements and we will be happy to help.
The ProGARM range of Flame Resistant protective garments are designed for every-day wear and protection – the highly breathable clothing ranges are designed for comfort and safety without compromising the ability of the wearer to work productively, safely and unhampered by cumbersome garments prone to overheating.
Other garments and protection products include Arc Flash Gloves, Arc Clothing, Arc Flash Suits and Arc Flash Helmets & Visors.
💡 Did you know? – While high voltage equipment does increase the likelihood and intensity of arc flash explosions, they can occur in any live electrical environment – even low voltage.
