Workplaces where both visibility and protection against thermal risks are required present a challenge when it comes to personal protective equipment. It is essential to conduct a thorough risk assessment to find the right combination of protection.
High visibility clothing according to EN ISO 20471 ensures that workers are clearly visible, especially in traffic environments and on construction sites. The standard divides protection into three classes depending on the amount of reflective and fluorescent material the garment contains.
Flame-resistant garments protect against risks such as fire flames, heat radiation, and electrical arcs. The relevant standards include EN ISO 11612 for heat protection and IEC 61482 for electrical arcs.
Combined products must therefore meet the requirements of both standards. This means that the materials must be both visible and withstand high temperatures.
The petroleum industry, railways, and electrical installations are typical work environments where both protections are needed. It is not uncommon for workers there to be exposed to both traffic risks and potential fire hazards.
Combining materials for both visibility and flame protection is not straightforward. Reflective materials can be affected by flame retardant treatments, and the strong fluorescent colors must still be visible after flame protection treatments.
The certification for combined garments is considerably more complex than for garments with only one protective function. Each combination must be tested separately against both standards.
The price for combined garments is often noticeably higher than for simple high visibility clothing. This is partly due to special materials and partly because the certification is more extensive.
Maintenance and washing are a bit trickier. Flame protection can deteriorate if washed incorrectly, and reflective details can be damaged by excessive heat.
A thorough risk assessment is necessary to identify all threats in the workplace. Traffic, fire risks, and electrical hazards must be mapped out.
It is important to choose the right protection classes for both functions. Class 3 high visibility clothing combined with flame protection provides the highest level of protection, but sometimes lower classes are sufficient depending on the task.
The Swedish Work Environment Authority provides guidelines for when combined requirements apply. Documentation of risk assessments and selection of protective equipment is mandatory according to work environment legislation.
It is not uncommon for the work environment to change over time, so regular reviews are wise. New work processes may require different protective functions than before.
Combined protective garments that are both visible and flame-resistant are subject to several European standards and Swedish law. The most important are EN ISO 20471 for visibility, EN ISO 11612 and EN ISO 14116 for flame protection, and EN 17353 for combined protection.
EN ISO 20471 is the standard that governs high visibility clothing and visibility at work. It divides garments into three classes where class 3 offers the best visibility and class 1 is the basic level.
All high visibility garments must be CE marked according to this standard. The certification requires a certain amount of fluorescent background material and retroreflective tape.
Class Division According to EN ISO 20471:
Reflective materials should be placed according to the standard to provide the best possible visibility from all directions.
EN ISO 11612 applies to protective clothing against heat and flame, primarily for industrial environments. It covers protection against convective heat, radiant heat, small splashes of molten metal, and brief contact with flames.
Garments are tested against several performance codes. A1 and A2 relate to flame spread, B to convective heat, and C to radiant heat. The F code indicates resistance to small splashes of molten metal.
EN ISO 14116 focuses on limited flame spread. There are three levels where index 1 is the base and index 3 provides the highest protection.
The materials must pass rigorous fire tests. Afterglow time and how much the material shrinks are measured to ensure it does not continue to burn.
EN 17353 is the standard for combined protective garments that are both visible and flame-resistant. It ensures that both protections work together in the same garment.
The garment must meet both EN ISO 20471 for visibility and either EN ISO 11612 or EN ISO 14116 for flame protection. No function should be compromised by the other.
Key Requirements According to EN 17353:
The certification process is quite intricate. The manufacturer must demonstrate that all components work together without degrading the protection.
The Work Environment Act requires employers to ensure that the right protective equipment is available to prevent ill health and accidents. The protective clothing must be adapted to the risks present at the site.
The Swedish Work Environment Authority oversees and issues regulations regarding personal protective equipment. Employers must conduct risk assessments and determine when combined protective garments are necessary.
Protective garments must be certified according to EU standards. Regular inspection and maintenance of the equipment is a requirement.
The Swedish Transport Administration also has its own requirements for road work sites, where high visibility clothing often needs to be combined with other protections. These rules complement the general regulations from the Swedish Work Environment Authority.

High visibility clothing is divided into three safety classes according to EN ISO 20471, depending on how much fluorescent and reflective material they contain. Each class provides different protection for those working in hazardous environments.
Class 1 is the basic level for high visibility garments and contains the minimum amount of visible material according to the standard. The garments must have at least 0.14 square meters of fluorescent material and 0.10 square meters of retroreflective material.
Typical class 1 garments include high visibility vests, reflective vests, and accessories such as armbands. They are best suited where the risk is low, traffic is moving slowly, and there is good awareness of the surroundings.
Class 1 is often used in:
It is important to remember that class 1 garments are not sufficient in high-risk environments. The reflectors and fluorescent material provide only basic visibility, nothing more.
Class 2 requires significantly more visible material than class 1. At least 0.50 square meters of fluorescent material and 0.13 square meters of retroreflective material are needed.
This classification provides improved visibility in more demanding work environments. Class 2 high visibility garments can be T-shirts, sweaters, jackets, or trousers with strategically placed reflectors.
The material covers larger body areas. This is really helpful when one needs to be seen in vehicle traffic's headlights under changing light conditions.
This safety class works for:
Airport operations, rescue services, and maintenance work also fall under this category. Class 2 garments give the worker a better chance of being seen both in daylight and darkness.
The reflectors are designed to reflect light from multiple angles. It is actually quite fascinating how much they can contribute to safety.
Class 3 is the pinnacle of protection levels. Here, at least 0.80 square meters of fluorescent material and 0.20 square meters of retroreflective material are required.
This is the highest safety classification for high visibility clothing according to EN ISO 20471. Class 3 garments cover most of the body and have reflectors on both the upper body and legs.
This coverage provides visibility from all directions, even under tough conditions.
Class 3 is a must for:
Aircraft traffic on runways and crane truck drivers are also included. Jackets or sweaters are often combined with trousers to achieve the right material area.
Reflective bands are placed on arms, legs, and torso. All to ensure that you are properly visible in traffic light.
You can actually combine different high visibility garments to achieve a higher safety class than what individual garments provide. A class 1 vest combined with class 1 trousers results in class 2 protection.
Combination rules are based on total material area:
This provides flexibility when the weather changes or tasks shift. You can start with a simple vest and add more garments as risks increase.
Combined garments must still be certified according to the same standard. The reflectors on different garments should not obstruct each other.
The employer must ensure that the combination actually maintains the correct safety class for the job.
Combined protective garments require that fluorescent and reflective materials are integrated with flame-resistant components. The design must ensure that visibility is maintained while heat protection is at its best.
Fluorescent material is the foundation for visibility in daylight. It works by converting UV radiation into visible light.
In combined protective garments, specially treated polyester systems are often used. They retain their properties even after treatment with flame retardants.
Requirements for Fluorescent Area According to EN ISO 20471:
| Class | Minimum Area of Fluorescent Material |
|---|---|
| Class 1 | 0.14 m² |
| Class 2 | 0.50 m² |
| Class 3 | 0.80 m² |
The material must be smartly placed over the garment. Larger areas are located on the chest and back, while smaller areas are on the arms and legs.
The fluorescent area must not be destroyed by seams or fasteners. Special seams are used where flame-resistant thread is combined with fluorescent tape.
Reflective material provides visibility in darkness. It involves retroreflection of light sources, often with glass bead reflectors or microprism technology.
Reflectors are placed in both horizontal and vertical bands around the body. Horizontal bands go around the waist, chest, and back, while vertical bands run over the shoulders.
This makes the body recognizable from a distance.
Minimum Reflective Area:
Reflective bands are attached with flame-resistant adhesive or sewn with special thread. The seams must be placed so that the reflective material still functions even under heat or chemical treatment.
Flame-resistant materials in combined garments consist of inherent flame-resistant fibers or chemically treated textiles. Aramid-based materials like Nomex or modacrylic blends are common choices.
All components must be flame-resistant – threads, elastic bands, Velcro, and zippers. Metal components should not melt or become too hot.
Seam construction requires special attention:
Reinforcements are needed at stress points. The construction should avoid air pockets where heat can accumulate.
Garments are designed to fit well without restricting movement. The material should lie close to the body for optimal protection.
Ventilation openings are placed where needed to release heat without compromising protection.

Combined high visibility and flame-resistant garments must undergo a rigorous certification process. The marking should clearly indicate which standards the garment meets.
Combined certification means that a garment is tested and approved for both high visibility and flame protection functions simultaneously. The garment must meet EN ISO 20471 for high visibility clothing and flame protection standards such as EN ISO 11612.
The certification body ensures that the materials work together. Flame protection must not reduce the performance of the reflectors or diminish the visibility of the fluorescent material.
The entire garment is tested as a unit. It is not sufficient for individual components to meet their respective standards.
Testing is conducted under various conditions to ensure that both functions hold up over time.
Combined certified protective clothing must be clearly marked on the label. EN ISO 20471 marking indicates the visibility class, while flame protection marking specifies the type of heat and flame protection the garment provides.
The label should include:
The manufacturer should provide detailed product information about limitations and areas of use. The information needs to be clear about which environments the garment is suitable for and when it should be replaced.
The testing process for combined high visibility and flame-resistant garments is quite strict. Both functions are tested in parallel.
Flame protection tests involve exposure to open flames, radiant heat, and molten metal. During these tests, it is checked that the reflective material and the fluorescent fabric still function.
Visibility tests measure light reflection and visibility both before and after flame protection tests. The certification process often takes 8–12 weeks depending on how advanced the garment is.
Accredited testing institutes verify the results. After successful testing, the garment receives a certificate specifying which performance levels it actually achieves.
Choosing the right high visibility clothing with flame protection involves analyzing workplace risks and matching protection levels against actual hazards. Comfort, certification, and functionality drive practical usability—and sometimes one has to compromise a bit between them.
Oil Industry and Petrochemicals require high visibility clothing with flame protection class 2 or 3 according to EN ISO 20471. This is combined with flame protection standard EN ISO 11612.
Workers are exposed to both traffic and potential flames from hydrocarbons. Not exactly a place for compromises.
Electrical Maintenance Work needs protective clothing against electric arcs combined with high visibility effectiveness. The EN 61482 series governs arc protection.
The visibility requirements follow EN ISO 20471. It is quite strict.
Railway Environment requires:
Durability for outdoor work is also a must. The weather never takes a break.
Refineries and Chemical Plants require the highest level of protection. High visibility vests are rarely sufficient.
Complete suits are needed with certified flame protection treatment. There is no debate about that.
Fire Brigade and Rescue Services use specially designed high visibility clothing with reflectors that withstand extreme temperatures. The combination of visibility and heat protection is critical for traffic accidents.
High Visibility Vests with flame protection are suitable for temporary work in low-risk areas. They are often made from cotton blends with inherent flame protection or chemical treatment.
High Visibility Trousers with reinforced knees and seats combine durability with flame protection properties. Brands like Blåkläder and similar manufacturers offer models certified according to both EN ISO 20471 and flame protection standards.
Jackets provide complete upper body protection with:
Reinforced Shoulder Areas against wear are a plus. It is rare for anyone to complain about too much durability.
Full-Body Overalls are used at the highest risk level. These combine visibility class 3 with flame protection for the entire body.
The material is often aramid fiber or cotton with permanent flame protection treatment. Feels safe.
Protective Clothing in sets from the same manufacturer ensures compatibility between garments. CE marking guarantees that the combination meets both protection requirements simultaneously.
Size Selection affects both safety and comfort. Too large garments can get caught in machinery.
Too small garments restrict movement in emergencies. Not exactly something you want to discover too late.
Breathability varies between materials. Cotton blends provide better comfort than synthetic flame-resistant materials.
However, they may have lower durability. It is a trade-off.
Weather Conditions dictate material choice:
Rain: Waterproof outer layers without compromising flame protection. No one likes to be wet and unprotected.
Washing and Maintenance follow the manufacturer's instructions. Incorrect handling can permanently damage both reflective materials and flame protection properties.
Ergonomics includes stretch panels and reinforced seam placement. Workers wearing protective clothing all day need optimal freedom of movement.
Combined protective clothing that offers both flame protection and high visibility requires special attention in care. Incorrect handling can permanently degrade both the visibility of the reflectors and the flame-resistant properties.
Washing Instructions must be followed exactly according to the manufacturer's guidelines. The temperature must never be exceeded.
High temperatures can damage both the fluorescent material and the flame-resistant fibers. It is easy to forget this in the laundry room.
Use of fabric softener is prohibited as it can clog fibers and reduce breathability of flame-resistant materials. Bleach and optical brighteners should be avoided as they break down fluorescent colors.
Drying should occur at low temperature or air-dried. Dry cleaning can only be used if specifically stated by the manufacturer.
Chemicals can affect both reflectors and flame protection treatments. An iron with too high a temperature can permanently damage reflective materials and flame-resistant fibers.
Reflective bands and fluorescent areas require extra caution when ironing. It is easy to accidentally burn something.
Immediate Cleaning after exposure to chemicals or flammable substances is critical. Some contaminants can neutralize flame-resistant properties even after washing.
Dirt and stains on reflective surfaces drastically reduce visibility. Regular inspection of visibility areas helps identify when extra cleaning is needed.
Mechanical Wear affects the function of reflectors faster than the fluorescent material. Damage to reflective bands or cracks in reflective surfaces make the garment unsuitable for use.
Users should document washing cycles and wear to follow the manufacturer's recommendations for maximum lifespan. Most combined garments can withstand 25-50 washing cycles depending on quality and usage.
Visual Inspection should be conducted before each use. Faded fluorescent areas, damaged reflectors, or visible signs of degraded material require immediate replacement.
Garments that have been exposed to flame exposure or chemical contamination must be replaced even if there are no visible damages. Flame-resistant properties can be compromised without external signs.
Insurance Aspects make proper maintenance critical. Insurance companies may refuse compensation in case of accidents if protective clothing does not meet certification requirements due to inadequate care.
Recertification through authorized testing may be possible for certain garments. However, the cost often exceeds that of new clothing.
Employers are responsible for ensuring that all protective equipment meets applicable safety standards. This is not something to take chances with.
Combined high visibility and flame-resistant clothing follow specific standards and certification processes. They ensure both visibility and protection against heat-related risks.
Maintenance and inspection of these specialized garments require special attention to maintain the protection level over time. Missing this can be costly.
Flame-resistant high visibility clothing must meet both EN ISO 20471 for visibility and EN ISO 11612 for heat protection. EN ISO 20471 regulates minimum requirements for retroreflective and fluorescent materials with classification from 1-3.
EN ISO 11612 specifies protection against heat and flames through limited flame spread and thermal insulation. The EN ISO 11611 standard specifically applies to welding work and requires additional tests for metal splashes and radiant heat.
Some applications also require EN 1149-5 for antistatic properties when there is a risk of explosion. Combined certifications mean that the garment undergoes all tests without compromising any protective function.
High visibility clothing according to EN ISO 20471 requires specific amounts of fluorescent background material and retroreflective bands for visibility. The class is determined by the total area of visible material combined with reflective areas and design requirements.
Flame-resistant clothing is tested against heat sources, flame spread, and melting of materials. The requirements include limited afterglow, no burning melt, and specified thermal insulation through the material.
Combined requirements mean that both visibility properties and flame protection must be maintained simultaneously. Reflective bands and fluorescent materials must not be degraded by flame retardant treatment or vice versa.
CE marking is a must for all personal protective equipment within the EU and shows that the garment meets basic safety requirements. There should also be a type approval from a certified testing institute according to relevant standards.
EN ISO 20471 with classification (1, 2, or 3) applies to visibility requirements. EN ISO 11612, with its coded performances for various heat sources, is also important.
A1 and A2 indicate how well the garment resists flame spread. B, C, D, E, and F relate to protection against different types of heat exposure.
Manufacturer certificates should show that combined tests have been conducted and that the protective properties do not compromise each other. It is a clear advantage if an accredited testing laboratory like RISE or similar institutes has conducted the certification.
A quick visual check before each use is actually necessary. Look for damage to reflective bands, wear on the fluorescent material, holes, or seams that have come undone.
If you find heavily soiled or damaged garments, they should be replaced immediately. It is not worth the risk to take chances.
Once a week, it is wise to conduct a more thorough inspection. This way, you can check that the reflective material is still securely attached and that the color has not faded too much.
It is easy to forget, but fading affects visibility more than one might think.
Many manufacturers require documented inspections, often monthly or after a certain number of washes. The Swedish Work Environment Authority believes that employers should have established routines for checking and replacing protective clothing.
The manufacturer's washing instructions should be followed closely; otherwise, both flame protection and visibility can be compromised. Often, the temperature limits are lower than for regular work clothes, specifically to protect chemical treatments.
Avoid fabric softeners and bleaches – they can destroy both flame protection and reflective materials. Industrial washing with certified processes is often best if you want to ensure everything is done correctly.
Drying according to the instructions is important, and air drying is actually often preferable. Machine drying or radiation drying can be too harsh.
Pressing and ironing? Only if it states that it is okay – and then with low heat; otherwise, the reflective bands can be damaged.
Reflective materials lose their retroreflective properties when scratched, soiled, or detached from the base material. In fact, even small damages can significantly reduce visibility in vehicle lighting.
Fluorescent materials fade from UV radiation, and after several washes, they lose their intensity. When the color changes from bright yellow or orange to a duller shade, daytime visibility decreases noticeably.
Flame-resistant properties can deteriorate due to chemical breakdown or when treatments wear off. Holes, torn seams, and thinner materials make the garment more vulnerable, especially where protection is truly needed.
