In order for a piece of clothing to achieve high visibility, it must be made from fluorescent materials and have reflective strips. Fluorescent materials allow a person to be seen during the day, this is the garment colour. Reflective strips give the wearer visibility during the night.
Besides materials and colour, there are 3 classes that determine the type of clothing required for a particular job, including the number of reflective strips and fluorescent materials needed.

Understanding this should help you determine the right Class of high-visibility clothing for your workplace.
Additional factors to consider are fit and temperature resistance. You’ll want to ensure your workwear is a good fit and comfortable. Depending on the climate of the workplace you may need to purchase insulated jackets or wicking fabric poloshirts. Never cover the high-visibility garments with extra jackets or other items of clothing.
One final consideration before buying your high-visibility workwear is to make sure it adheres to the required EN standards, these guidelines are there to protect the wearer and passer-by.
High-visibility workwear must protect against rain, snow and fog. It must also be water resistant and water vapour resistant.
High-visibility workwear must be suitable for professional use. The suitability is determined by X and Y performance classes.
X – Surface area of fluorescent and retroreflective materials
Y – Quality of retroreflective materials
High-visibility clothing not suitable for professional use. This means that the visibility level is only suitable for those who are not using it for work, including children and pedestrians.
Colours, sizes, and materials are all factors to how effective high-visibility clothing will be in the workplace. These practical concerns should also be combined with the recognised standards for this type of workwear. With these considerations in place, you’ll be able to know exactly what kind of garment you need for the task at hand.
