UV PROTECTION THAT WORKS
As temperatures rise in summer, PPE helps to protect outdoor workers’ health and safety. While sunscreen often takes center stage in sun protection, it's far from the only solution. PPE offers a practical way to protect the body from heat discomfort and long-term damage.
Skin cancer rates are rising, and product claims are becoming harder to trust. That’s why we need to understand UV radiation better. The right fabrics can help protect the body in a strong and lasting way. The right clothing doesn’t just help you stay cool now, it plays a vital role in preserving your health for the future.
UV radiation: The invisible risk
People can’t feel or see UV radiation like they can temperature, which is exactly why they so often misjudge it. UV exposure is highest in summer, especially between noon and 4 p.m. It can still be dangerous on cloudy or cooler days.
three types of UV rays:
- UVA (320–400 nm): These rays penetrate deep into the skin and eyes. They’re the most prevalent and can cause short-term and long-term damage over time.
- UVB (280–320 nm): Less abundant but more intense, these rays are responsible for sunburn and contribute to skin cancer.
- UVC (100–280 nm): It's the most dangerous form of UV radiation, typically only encountered on earth while welding.
What makes clothing UV-protective?
At first glance, it may seem like any long-sleeved shirt can protect the skin from the sun. When it comes to UV rays, the type of fabric makes a big difference. Some fabrics offer stronger ultraviolet protection than others. Some materials still allow UV radiation to pass through more easily than people might expect.
Clothing designed for real UV protection is tested to show how well it blocks harmful UV rays. This is especially important for people who work outdoors and are exposed to the sun for long periods of time.
One of the most commonly used standards for ultraviolet protection in clothing is EN 13758-2. This standard measures the Ultraviolet Protection Factor, or UPF, of a garment. The UPF rating shows how effectively the fabric protects the skin against UV radiation. A higher UPF means stronger protection against UV rays and better long-term protection for the wearer.
Several factors influence protective capacity:
- Fabric density: Tightly woven fabrics block more UV rays than loose weaves.
- Color: Dark or bright colors absorb more UV radiation than lighter shades.
- Fit: Loose-fitting improves a good air circulation and offers better protection than tight-fitting styles, which can stretch the fabric and reduce its density.
- Condition: Wear and tear, stretching, or thinning of fabric can all compromise protection levels over time.
- Water-soaked apparel: Water-soaked apparel compromises the UV-blocking capability of your clothing.
*Other test standards are UV STANDARD 801, AS/NZS 4399, AATCC TM 183
Not all UV claims are created equal
The term “UV-protective” can be misleading when it is not supported by proper testing or certification. Many garments are promoted as “anti-UV” or suitable for sun protection, but this does not always mean they offer reliable ultraviolet protection.
Without a tested UPF rating or a recognised standard, it is difficult to know how well the fabric actually blocks UV rays. Some clothing may cover the skin, but still allow UV radiation to pass through. This can give the wearer a false sense of protection, especially during long periods of outdoor work.
Clear labeling and certified testing help prove the real level of ultraviolet protection a garment provides. They make it easier to choose clothing that offers dependable protection against UV rays, rather than relying only on marketing claims.
When evaluating UV-protective clothing, look for:
- CE certification according to EN 13758-2
- Transparent product information, not just icons or marketing slogans
- Evidence of third-party verification, not just manufacturer claims
But just how much protection does a UPF rating actually provide?
Preserving Performance Through Care
To keep UV-protective clothing working well over time, proper care is important. Even fabrics designed to block UV rays can lose part of their protective function when they become worn, stretched, damaged, or too thin.
That is why garments should be checked regularly, especially when they are used often or exposed to strong sunlight for long periods. Visible signs of wear, such as thinning areas, loose fibres, stretching, small holes, or damaged seams, can reduce the level of ultraviolet protection. When the fabric no longer performs as intended, more UV radiation may pass through and reach the skin.
For reliable ultraviolet protection, protective clothing should be maintained according to the care instructions and replaced when the material shows clear signs of damage or loss of quality
Knowledge as first layer of protection
UV protection is an important part of everyday health and safety, especially for people who work outdoors. Long hours in the sun can expose the body to UV rays, which may lead to both short-term skin damage and long-term health risks.
Understanding how UV radiation works helps us make safer choices. It also shows why the right clothing matters. A garment that offers real ultraviolet protection does more than cover the skin. It helps block harmful UV rays and reduces the amount of UV radiation that reaches the body.
By choosing fabrics with reliable ultraviolet protection, outdoor workers can stay better protected during the day. This helps support safer working conditions, especially in summer or in environments with high sun exposure.
