Boosting visibility in low-light conditions is crucial for Hi-Vis clothing wearers. Ensuring continued compliance with ISO 20471 for luminance and chromaticity standards is a challenge.

When a garment is new, conformity will have been established by the manufacturer and labelling, supported by certification, will confirm it. But continued exposure to sunlight will progressively reduce the luminance and chromaticity and short of testing the garment on a regular basis, how else can you be expected to ensure that the garment remains compliant?
Until now, you couldn’t…

MiRiCal Emblems Ltd presents Sun-Safe Indicator

Sun-Safe Indicator is an innovative solution for maintaining compliance with a simple visual cue. No more guesswork or expensive testing is needed!

How does it work?

Sun-Safe Indicator incorporates specially developed inks that fade at a rate similar to the Hi-Vis fabric, whether yellow, orange or red, indicating when it’s time to replace the garment. The indicator cleverly reads “un-Safe” when it’s time for a new garment. Don’t take our word for it, it has been fully tested at an independent laboratory in the UK.

Don’t miss out on the extra security and peace of mind that Sun-Safe Indicator provides. It can be applied at any stage in the production process – manufacturer, wholesaler, or retailer, with just a conventional heat press. Embrace this cutting-edge solution for Hi-Vis clothing providers, Health & Safety Managers, and wearers alike!

Stay safe, stay visible with Sun-Safe – Your Hi-Vis Compliance Indicator!

The Sun-Safe Indicator is patent pending worldwide and is available exclusively from MiRiCal Emblems Ltd in the UK, via its offices in Europe, and distributors globally. For further details, pricing, application advice etc. please contact
