As the old saying goes, “safety first.” When it comes to hazardous working environments, high visibility or “hi vis” workwear can be an integral part of keeping workers safe and preventing accidents.
hi vis workwear includes clothing and accessories that feature bright and reflective materials, making them highly visible to others. These clothing items are commonly used in many industries such as construction, manufacturing, road work, or any other field where the workers are exposed to moving vehicles or heavy machinery.
The bright and fluorescent colors of hi vis workwear make workers stand out in low light conditions, which can be beneficial in preventing accidents such as collisions with vehicles or other heavy machinery – the major causes of workplace fatalities. Reflective materials are used on vests, jackets, shirts, trousers, and even helmets to enhance hi vis safety workwear’s visibility in dark and low-light situations.
hi vis workwear does not only increase safety, but it is also a legal requirement in many industrial sectors. Regulations state that workers who are exposed to traffic must wear high-visibility garments that comply with a specified standard to ensure that they are visible to drivers, machinery operators, and other workers.
Choosing the right hi vis workwear is vital as it determines the degree of visibility and safety. There are different classes and levels of hi vis workwear that are designed to cater to different levels of worker exposure. For example, a traffic controller working on the road will require a higher visibility level than a worker operating machinery in a factory.
The standard categorization for hi vis workwear includes three classes: Class 1, Class 2, and Class 3. Each class corresponds to the level of visibility needed, with Class 1 providing the lowest level of visibility and Class 3 providing the highest level.
Class 1 clothing is suitable for minimal risk situations, mainly for indoor work where workers are not in contact with heavy machinery or toxic substances. It includes items such as vests, jackets, and trousers with a minimum of 0.14m^2 of fluorescent material and no reflective stripes.
Class 2 clothing is for high-risk worksites, including roles that require the workers to work near moving vehicles or traffic. Items include vests and jackets with a minimum of 0.50m^2 of fluorescent material and retro-reflective stripes.
Class 3 clothing offers the highest level of visibility and is designed to be worn in the most dangerous environments such as motorways, airports, and rail tracks. Class 3 workwear requires a minimum of 0.80m^2 fluorescent material and retro-reflective stripes.
Apart from selecting the right class of the workwear, choosing the correct fabric and material is also important. hi vis workwear needs to be visible and durable, maintaining its brightness and reflectivity after being washed or rubbed against machinery, walls, or other objects. Some fabrics and materials that are commonly used in hi vis workwear include polyester, nylon, and cotton-polyester blends.
Polyester is the most commonly used material in hi vis workwear due to its high durability, bright coloration retention, and its ability to be mixed with other fibers like cotton. Polyester retains its strength and color after long periods of use, making it ideal for hi vis clothing.
Nylon is also used in hi vis clothing and is known for its lightweight, high strength, and resistance to abrasion and tearing. Clothing made from nylon is suited for working in harsh environments, such as road or rail maintenance.
Cotton-polyester blends combine the breathability and comfort of cotton with the durability and color retention of polyester. Clothing made from cotton-polyester blends are comfortable to wear, making them ideal for workers exposed to extended periods of heat or the warm temperatures associated with working outdoors.
In conclusion, hi vis workwear is an essential aspect of ensuring safety for workers in hazardous environments. These clothing items are not only beneficial for workers, but they are also a legal requirement in many countries worldwide. With different levels of visibility required for different jobs, selecting the right class of hi vis workwear that suits a particular type of work is critical, as is choosing the right fabric and material. Ultimately, the right hi vis workwear can help prevent accidents, injuries, and fatalities. Remember that safety is paramount, and wearing high-visibility clothing is a simple yet effective way of ensuring it.
