Working with metal, whether welding, cutting, grinding or assembling components, always involves high risks for the operator. Sharp workpiece edges, hot chips, abrasive particles and vibration are everyday factors that threaten the integrity of the skin of your hands. That's why gloves for working with metal are not just an element of workwear, but a critically important personal protective equipment (PPE), the quality of which determines the health and performance of the worker.
Incorrectly selected protection can lead to serious injuries: from deep cuts to tendons to burns and microscopic metal dust getting under the skin. At the same time, too bulky gloves reduce tactile sensitivity, which is dangerous when working with precision tools or moving machine mechanisms. The balance between protection, comfort and maneuverability is key when choosing equipment.
The modern market offers many solutions: from classic split leather to high-tech composite threads with Kevlar. Understanding the differences in materials and protection classes allows you to create the optimal arsenal for a specific task. In this article we will examine in detail the types of materials, safety standards and nuances of using protective gloves in intensive metalworking conditions.
Main risks when processing metal and requirements for personal protective equipment
Metalworking creates a unique combination of hazards that are rarely found in other industries. The main threat is the mechanical impact of sharp edges and chips. The chips produced by turning or milling can be extremely hot and razor-sharp. If such chips get inside a glove or on exposed skin, it will cause instant burns and lacerations.
The second critical factor is abrasive wear. When working with grinding wheels or cleaning welds, metal and abrasive particles act like sandpaper, quickly abrading ordinary fabric gloves. If the material of the mitten is not sufficiently resistant to abrasion, it will lose its protective properties in a matter of minutes, leaving your hands vulnerable.
⚠️ Attention: Never use cotton gloves when working with rotating machinery (drilling machines, lathes). The fabric may become wrapped around the spindle, causing severe hand injury. Such operations require special solutions or work without gloves using other protective equipment.
The third aspect is thermal impact. Even if you don't weld, the freshly machined part can still be hot. Gloves must provide short-term contact with hot surfaces without burning or transferring heat. In addition, protection from molten metal splashes that may occur during arc cutting or welding is important.
- 🛡️ Mechanical cuts: risk of damage from sharp sheet metal edges and chips.
- 🔥 Thermal burns: contact with hot parts and sparks.
- 🌪️ Vibration: prolonged exposure to vibration from power tools.
- 🦠 Chemical exposure: contact with coolants (cutting fluids) and oils.
When choosing protection, it is necessary to take into account the specifics of the operation. Thick leather is required for roughing (moving) heavy pipes, and thin but strong threads are required for assemblies. There are no universal gloves “for all occasions”, so professionals often have several pairs for different tasks.
Materials: leather, Kevlar and composites
The traditional and still most popular material for protecting the hands of metallurgists and mechanics remains genuine leather. Most often, split leather (the bottom layer of the hide) or full grain leather is used. Split gloves are distinguished by their high density and ability to withstand short-term contact with sparks. They do not melt, but only char, which makes them ideal for welding and working with hot chips.
However, leather has its drawbacks: it is heavier than its synthetic counterparts, can become tan in the cold and takes time to “break in”. To increase moisture resistance and protect against oils, the leather is often impregnated with special compounds. In conditions where not only mechanical strength is important, but also protection against cuts, synthetic materials come to the fore.
Kevlar and Dyneema are ultra-high strength fibers that are used to create gloves with a high cut protection class (from 3 to 5 classes according to EN 388). These gloves are thin, lightweight and provide excellent tactile sensitivity. They are ideal for working on sharp sheet metal edges where precise movements are important.
Why can't Kevlar gloves be washed at high temperatures?
Although Kevlar is heat-resistant, aggressive washing powders and high temperatures can destroy the fiber structure or damage the impregnation, reducing its protective properties. We recommend gentle washing according to the manufacturer's instructions.
Combined models combine the best properties of different materials. For example, the palm may be made of leather for protection against abrasion and sparks, and the back of the elastic knit with patches of Kevlar for ventilation and protection against cuts. Nitrile or PVC coating on the palm adds protection against oils and improves grip on slippery metal parts.
- 🧶 Aramid threads: High heat resistance and cut protection.
- 🐂 Genuine leather: resistance to sparks and punctures.
- 🧤 Nitrile coating: oil and petrol resistance and improved grip.
When choosing a material, you should also pay attention to the presence of a lining. The cotton lining provides comfort and absorbs sweat, but wears out faster. Unlined models are more durable and provide better tactile sensations, but may be less comfortable when worn for long periods in hot weather.
Protection classes and standards (EN 388, ISO)
In order not to guess about the strength of gloves, there is a unified European standardization system EN 388, which marks products with a pictogram with a shield and four (or six) numbers below it. Understanding this marking is a mandatory skill for the occupational safety specialist and the worker himself.
The first number indicates abrasion resistance (from 1 to 4), the second is knife cut resistance (from 1 to 5), the third is tear resistance (from 1 to 4), and the fourth is puncture resistance (from 1 to 4). When working with chips and metal, the most important indicators are resistance to cuts and punctures. A high cut protection class (4 or 5) means that the glove will withstand contact with a sharp edge.
| Parameter | Class 1 | Class 3 | Class 5 (Max) |
|---|---|---|---|
| Abrasion (cycles) | 100 | 2000 | 8000+ |
| Cut (index) | 1.2 | 5.0 | 22.0+ |
| Razdir (Newton) | 10 | 35 | 50+ |
| Puncture (Newton) | 20 | 60 | 150+ |
A separate standard applies for welding work. EN 12477, which divides gloves into type A (for welders, high protection, less dexterity) and type B (for gas welders, high dexterity, less protection). Type A gloves are typically thicker and provide better protection against molten metal splash, which is critical when working with manual arc welding.
It is also worth considering the standard EN 407regulating protection against thermal risks. The markings may include information regarding resistance to contact heat, convection heat, radiant heat, and molten metal splashes. For foundry and welders, the presence of splash protection symbols (drops) is mandatory.
For work with sharp chips and thin metals, priority is given to cut protection class (3-5 according to EN 388), and for welding, heat resistance and splash protection (EN 12477).
Specific selection for welding, cutting and assembly
The choice of gloves directly depends on the technological process. When electric arc welding (MMA) produces large amounts of molten metal spatter and intense UV radiation. Here you need long leggings made of thick split leather that cover not only the hand, but also part of the forearm. Cuffs often have valves to prevent sparks from entering.
For argon welding (TIG) The requirements for finger dexterity are much higher, since the welder needs to polish thin wire. In this case, gloves made of thin, soft leather (often goatskin) that fit tightly to the hand are used. They provide the necessary sensitivity, but require more frequent replacement when burns occur.
When metal cutting (grinder, scissors) and working with sheet metal, the main danger is razor-sharp edges. This is where leather gloves may be too rough. The best choice would be gloves made of composite threads (HPPE, fiberglass) with a nitrile coating. They are not afraid of oils, fit perfectly on the hand and cut metal while remaining intact.
⚠️ Attention: If you work with vibrating tools (grinders, impact wrenches), choose gloves with gel or foam shock-absorbing inserts on the palm. This will reduce the risk of developing an occupational disease - vibration disease.
In assembly shops, where you have to work with small parts, fasteners and sharp corners of cases, tactile sensitivity is important. Thin gloves with a cut protection class of 3-4 allow you to feel threads and small holes, protecting your fingers from splinters and cuts. Using mittens that are too thick in these conditions reduces productivity and increases the risk of errors.
Glove care and wear control
Even the most expensive gloves for working with metal and shavings will not last long without proper care. Metal dust, shavings and cutting fluids (cutting fluids) quickly destroy the structure of the material. Oils can dissolve some rubber coatings, making them sticky or brittle.
Inspect the surface of your gloves regularly. The presence of burns, through cuts or areas worn down to threads is a signal for immediate replacement. The use of damaged PPE is prohibited, as they lose their protective properties. Metal shavings trapped inside the glove may rub the skin or cause burns the next time they come into contact with a hot part.
☑️ Checking the condition of gloves
It is recommended to periodically treat leather gloves with special conditioners or water-repellent impregnations to prevent the leather from drying out and cracking. Coated knitted gloves can be washed (if allowed by the manufacturer), but after washing it is necessary to check whether the coating has lost its properties. Dirty gloves are not only unhygienic, but also more slippery, increasing the risk of tools slipping.
- 🧼 Cleaning: Remove metal shavings with a brush after each shift.
- 💧 Drying: dry wet shoes and gloves at room temperature, not on a radiator.
- 👀 Visual control: check the integrity of the seams and coating before starting work.
Typical mistakes when choosing and using
One of the most common mistakes is the desire to buy gloves “with a margin” in size. Gloves that are too large for metal work are dangerous: they reduce sensitivity, interfere with the normal grip of the tool and, most importantly, can be caught by the rotating parts of the machine. The glove should fit tightly, like a second skin.
Another mistake is using generic housekeeping gloves for professional work. Thin latex or PVC used in everyday life instantly breaks on sharp shavings or melts from a spark. Professional gloves for working with metal undergo certification and tests, household ones do not.
If you are working with non-ferrous metals (copper, aluminum), make sure that the gloves do not contain silicone, which can contaminate the surface of the weld and cause defects (pores).
Ignoring allergic reactions is also common. Some synthetic materials or powder coatings inside gloves may cause dermatitis when worn for long periods of time. If you experience itching or irritation, try a different brand or cotton-lined glove. Healthy hand skin is the key to a long career in metalworking.
⚠️ Attention: Do not attempt to repair torn protective gloves using glue or thread. It is impossible to restore the factory protection class at home, and such “savings” can cost your health.
The correct selection and use of gloves is not a formality, but a necessity. Chips and sharp edges are unforgiving. Investments in high-quality PPE pay off in preserved health and the absence of injuries. Always check the markings, monitor the condition of your equipment and do not neglect hand protection even when performing a “five-minute” operation.
What to do if metal shavings get under your skin?
Do not try to pick it out with dirty hands or a tool. Treat with an antiseptic and go to the emergency room, especially if the chips are deep or hot. Metal dust can cause inflammation or blood poisoning.
What are the best gloves for working with sharp stainless steel?
When working with stainless steel, which produces very sharp chips, gloves with a high cut protection class (class 4-5 according to EN 388) are best suited. They are made from HPPE (high molecular weight polyethylene) threads or composite materials with fiberglass. Leather gloves may be less effective against thin cutting edges here.
Is it possible to use welding gloves when working with an angle grinder?
It is not recommended to use thick welding gloves when working with an angle grinder (grinder). They are too bulky, reduce control over the tool, and can wrap around the disc if your hand slips. For an angle grinder, you need thick gloves with a class of protection against abrasion and cuts, but with good tactile sensitivity.
How often should you change gloves?
The frequency of replacement depends on the intensity of work. On average, a pair of metalworking gloves lasts from one shift to several days. The main rule: gloves are changed immediately if through damage appears, severe abrasion of the coating or loss of elasticity. Don't wait for them to turn into rags.
Do gloves protect against electric current?
Regular gloves for working with metal and shavings do NOT protect against electric shock. For electrical installation work, special dielectric gloves are required (for example, according to the EN 60903 standard), which are separately tested for breakdown. Using ordinary leather or knitted gloves when working under voltage is deadly.
