Safety Classes and Design of High-Visibility Clothing
High-visibility clothing is divided into three classes based on the amount of fluorescent and reflective material. Each class is tailored for different risk environments and job tasks.
The design is governed by requirements for material properties and placement to provide the best possible visibility.
Protection Classes 1, 2, and 3 – Differences and Usage
Class 1 has the lowest visibility and is used where the risk is low. A minimum of 0.14 square meters of fluorescent material and 0.10 square meters of reflective material is required. Typical for warehouse jobs and environments with little traffic.
Class 2 provides better visibility and requires at least 0.50 square meters of fluorescent material and 0.13 square meters of reflective material. Suitable for railway work, airport jobs, and construction with moderate traffic.
Class 3 is for the most exposed environments, requiring at least 0.80 square meters of fluorescent material and 0.20 square meters of reflective material. This includes road work, tunnel construction, and other places with heavy traffic.
Fluorescent and Reflective Materials
Fluorescent materials absorb UV light and make it visible, giving that intense color that really stands out in daylight. Yellow fluorescent material is usually the best for visibility, but orange and red are also used sometimes.
Reflective materials send light back towards the source. Retroreflective strips are strategically placed on the clothing to highlight the body's contours and movements. The material must maintain its properties even after many washes and wear.
The fluorescent surface should be evenly distributed across the garment according to the standard. The combination of both materials ensures visibility in daylight, twilight, and when headlights illuminate the garment in darkness.
The Importance of High Visibility
High visibility reduces the risk of accidents at work. It is about making people visible from a distance, regardless of whether it is light or dark.
Studies show that the right high-visibility clothing can be seen from 150 meters away. Regular work clothes? They are only noticeable from 38 meters, so the difference is quite significant.
The choice of color matters, and it is no exaggeration. Yellow-green stands out against most backgrounds, while orange works better in environments where there is already a lot of yellow and green.
The placement of reflectors is not random. They follow the body's lines to make the silhouette clear, allowing drivers to estimate distance and movement.
Horizontal and vertical bands are combined to create that typical silhouette. This makes it easier for others to quickly perceive if someone is in the way.
Adjustment and Maintenance of High-Visibility Clothing
High-visibility clothing must fit properly and be cared for. Otherwise, they lose their function faster than one might think.
The right size provides both comfort and visibility. Care and storage are crucial for the reflectors to function as intended.
Correct Size and Fit
High-visibility clothing needs to fit correctly to meet EN ISO 20471 requirements. Garments that are too small or too large can compromise the placement of reflectors and make movement difficult.
Jackets and vests should be fastened or closed when in use. Otherwise, the certification is not valid.
When choosing size, the garment should not ride up or twist when you move. Reflective strips must be positioned correctly around the torso and arms; otherwise, it will not be approved.
If you wear work clothes under the high-visibility clothing, a larger size is often needed. It is easy to forget this, and suddenly everything feels too tight.
If you are combining different high-visibility garments, they should be from the same brand and standard to be approved. This is especially important if you mix jackets and vests to achieve a higher safety class.
Protective clothing that does not fit can actually become a safety risk. It may not be obvious, but it happens.
Care Instructions and Washing Guidelines
High-visibility clothing loses its protective effect over time, especially if they become dirty or worn. Always follow the manufacturer's washing instructions; otherwise, the effectiveness of the reflectors can diminish faster than one might think.
Many high-visibility garments can only withstand a certain number of washes. It is easy to overlook, but it is important.
Important Care Rules:
- Wash at a maximum of 60°C unless otherwise stated
- Avoid bleach and optical brighteners
- Air dry rather than tumble dry
- Check the reflectors after each wash
Dirt and chemicals can completely destroy the reflectors. Stains? Remove them immediately; otherwise, they can become permanent.
If the garment is worn or damaged, the entire garment must be replaced. Certified high-visibility clothing cannot be repaired arbitrarily.
Storage for Maintaining Protective Effect
Proper storage ensures that high-visibility clothing lasts longer. They should be kept dry and protected from direct sunlight; otherwise, the reflectors can fade.
Extreme heat or cold is also not good for the material. It can become stiff or brittle.
The storage area should be clean and free from chemicals. Hang the garments so that the reflective strips do not get unsightly creases.
It is wise to check the clothing regularly while in storage. Damage can occur when you least expect it.
Checkpoints for Storage:
- Condition of the reflectors
- Durability of the seams
- CE marking must be legible
- No signs of wear or damage
