Näkyvyysvaatteiden

Näkyvyysvaatteet, often referred to as high-visibility clothing or hi-vis garments, are designed to make the wearer more conspicuous in hazardous environments, particularly in low light conditions or against complex backgrounds. The primary purpose of these garments is to enhance safety by alerting others to the presence of the wearer, thereby reducing the risk of accidents.

The effectiveness of näkyvyysvaatteet relies on two key properties: fluorescent materials and retroreflective materials. Fluorescent fabrics, typically in bright colors like yellow, orange, or red, absorb ultraviolet light and re-emit it as visible light, making them appear brighter and more noticeable during daylight hours. Retroreflective materials, on the other hand, are designed to bounce light back towards its source. This means that when light from headlights or other illumination sources hits the reflective strips on the clothing, it is reflected directly back to the observer, making the wearer highly visible in darkness.

Näkyvyysvaatteet are essential personal protective equipment (PPE) in many occupations. These include road construction workers, emergency responders, railway personnel, airport ground staff, forestry workers, and anyone operating near moving vehicles or machinery. The specific requirements for näkyvyysvaatteet are often dictated by national and international standards, such as EN ISO 20471 in Europe, which classify garments into different classes based on the amount of fluorescent and retroreflective material and their placement, indicating the level of visibility provided. Proper selection and use of näkyvyysvaatteet are crucial for ensuring worker safety.
