The best way to protect your face while working with an angle grinder


Interacting with any tool, both electrified and mechanical, always poses a health hazard. One of the most popular devices at work and at home is the angle grinder.

The scope of its application is very wide. Scale, dust and small particles fly out from under its disk. Therefore, to protect the eyes, safety glasses are used when working with an angle grinder.

Terms of use

The main danger for the operator lies in the angle grinder mechanism.
During operation, the grinder disk rotates and touches the surface being processed. At this moment, the master must hold it suspended with his own hands without the use of additional objects or assistants. That is why one careless movement can turn into a tragedy, breaking off and creating a sharp jerk of the instrument. This is why beginners are not trusted with professional tools. It’s better to start getting acquainted with an angle grinder with a device whose disk diameter is 115-125 mm

It is better to start getting acquainted with an angle grinder with a device whose disk diameter is 115-125 mm.

If you properly understand the safety precautions for working with an angle grinder, there is nothing to worry about. Safe work rules:

  1. During operation, the grinder is held with only two hands. In this case, you need to move it calmly, without pressing or applying force to the device.
  2. The operator stands firmly and firmly on his feet or knees while cutting or grinding. A comfortable position will help prevent falls and the device slipping out of your hands during sudden jerks.
  3. The power cable connected to the outlet is located behind the operator's body and should not be placed on the surface being processed. Otherwise, the resulting sparks can burn through it and cause a short circuit.
  4. It is prohibited to leave the grinder on and leave it. You can move around the room only when the device is turned off.
  5. If during operation there is a power outage, the power cord of the angle grinder is pulled out of the outlet, and the start button is moved to the off position.
  6. The diameter of the grinder disk must exceed the thickness of the surface being processed.

For what purposes are metal scissors used?

  1. In the automotive industry. This includes the creation of flat rectangular blanks and shaped elements with turned sides and made holes.
  2. In construction. Creating parts for the roof and cutting metal elements to prepare the base of the building.
  3. At metal yards for cutting rolled metal to meet the various needs of residents.
  4. In the work of rescuers. Such scissors are quite often used for sorting out all kinds of rubble due to collapse due to bad weather.
  5. When dismantling various equipment and scrap metal.
  6. At home. The use of scissors greatly helps owners in minor repairs of metal structures and more.

Common defensive ammunition

Various personal protective equipment are mandatory when using power tools. This is primarily due to the presence of chips, sparks and other elements that are formed during the work process and can cause harm to the human body. To avoid various types of injuries, people have developed simple and effective protective equipment that helps make the work process more comfortable and safer.

Eye protection glasses

This is a mandatory element of equipment when working with an angle grinder. It is advisable to opt for closed-type glasses that tightly fit the shape of the face and prevent foreign elements from getting into the eyes. This is due to the fact that the flight path of metal shavings, sparks and scale is unpredictable, and they can get under a protective mask or glasses. Therefore, before purchasing, it is advisable to always try on and adjust the product to suit yourself. The material used in the manufacture of the protective product also plays an important role.

It is important that the plastic has a high degree of strength and can withstand mechanical stress.

Masks

These are more reliable protective equipment than glasses, as they can cover not only the eyes, but the entire face. Unfortunately, in order to save money, some manufacturers use materials that are not of the highest quality, which affects the level of protection. Therefore, it is worth choosing masks from well-known manufacturers that look quite durable and have a protective mesh. This additional element is primarily intended to protect a person’s face when working with an angle grinder, since the cutting wheel can burst and fly into the eyes at great speed, and the mesh can stop it.

Mittens and gloves

It is impossible not to mention these most common, but no less important protective elements. When using an angle grinder, your hands are located in close proximity to the rotating disk and therefore require high-quality protection. Conventional gloves used in construction are not able to cope with the given protective task in all situations, since they are highly flammable and therefore quickly burn out from sparks, leaving burns on the body. When working with an angle grinder, it is better to use gloves made from rough leather or products with a rubberized base.

Also, if you have welding gaiters, which are made using durable suede, you can use them when working with power tools. Due to the high base of this type of gloves, they are able to protect not only the fingers and palms, but also the forearms.

How do open funds differ from closed ones?

Safety glasses are divided into:

  • open type;
  • closed type.

Open - this is the easiest way to protect your eyes when working with the possibility of injury. In appearance they resemble sunscreens. A distinctive feature is the absence of a frame. Most often, they are equipped with large, high-strength glass.

The shape of the glasses may vary, as long as the glass is wide enough to protect your eyes.

A rubberized pad is usually installed on the nose pad, which prevents the glasses from sliding down. For fixation on the head, arms or an elastic band are used, which is attached to the arms.

Open type glasses are different in that there are gaps between the person's face and the glasses into which metal particles or sparks can get caught. Such means do not provide the worker with 100% protection. When working with radiation, open glasses can be equipped with light filters. On sale there are lenses of all shades from yellow to brown, black, gray.

Lenses may have a polarizing coating. This allows the use of a protective accessory when working with ultraviolet, infrared and laser radiation. Open glasses belong to the category of cheap protective equipment.

Closed-type glasses are considered the safest. They are made of double panoramic glass, which is built into a protective mask. The mask ensures that the accessory fits tightly to the face, which allows you to increase the degree of protection when working with an angle grinder.

Closed glasses not only prevent metal particles and sparks from entering the eyes, but also do not create a barrier to dust, smoke, or harmful chemicals.

Closed-type glasses are secured to the head using an elastic band. The elastic band has adjustment elements, which makes the glasses a universal protective device.

Among the variety of models, you can find glasses with direct and indirect ventilation, with the ability to work with different types of radiation. Despite the fact that closed-type glasses are more bulky, have more weight, and can fog up in the absence of ventilation, they are preferable when working. This is due to their increased safety.

An ultraviolet filter is added to the lenses of protective devices.

The main task of safety glasses with an ultraviolet filter is to reflect the long ultraviolet wave UV(A). Such devices can be made with transparent glass or have different colors.

It is important to understand that they do not distort the main color of the image. On the contrary, glasses give the picture clarity; colored lenses can give the image a tint, but not color it in other colors

To manufacture UV protective devices, lenses with several layers of absorbers are used. These layers absorb UV radiation. There is also a polarizing layer. Its job is to protect the eyes from light reflected from objects. This combination of layers allows you to make the visible picture clearer and reduce eye fatigue when working.

Different models may have different degrees of protection. Manufacturers indicate all the information on the temples of the glasses or in the product passport. The UV 400 indicator indicates that the eyes in such models will be protected from A and B waves. With the B-15 marking, the protection will be 85%, and with the B-5 it will be 95%.

Among the features of glasses with an ultraviolet filter are:

  • protection against eye opalescence during prolonged work with ultraviolet radiation;
  • absorption of waves whose lengths are no more than 365 nm;
  • reduction of eye strain;
  • providing increased contrast when using powder and capillary non-destructive testing methods to study defects;
  • protection against low- and medium-energy impacts;
  • protection from solid particles and dust getting into the eyes.

Comparison with protective masks when their use is necessary

Masks are analogues of protective devices. When working with an angle grinder, using a mask is important when you have to work with the tool for a long time every day. The first difference between a maxi and glasses is its size. It protects not only the eyes, but also the entire part of the head. Masks for working with an angle grinder are in demand when an angle grinder is the master’s main tool.

The second difference between the mask is its cost, which is several times higher than the price of the devices in question. Often masks are additionally equipped with protective nets over the glass, which allows for maximum protection of the face and head as a whole. When using an angle grinder, it is important to follow safety precautions, which will allow you to complete the work you started without getting injured.

Materials

Eye safety is especially important if a person performs work in difficult conditions. Glass protects against chemicals, debris, glass. Such protective equipment is indispensable in the woodworking industry and construction.

Safety glasses can be tinted or clear. The color of the lens can be selected based on your own comfort. If you have to work in bright sun or with welding, then it is better to choose dark glasses.

Products can be in a plastic or metal frame.

Each model offered on the market has its own place in the safety rating. This rating means the lenses have been tested to withstand impact. The more expensive the glasses, the greater the mechanical impact their lenses can withstand.

On the market you can find models with adjustable straps or anti-fog lenses.

The described means of protection are of several types:

  • glass;
  • plastic;
  • plexiglass;
  • polycarbonate.

Scratches do not remain on the glass over time, but the problem is that users often complain that the material is heavy and causes discomfort. Glass is also prone to fogging.

Plastic is lighter compared to glass. It is also less prone to fogging. The problem is that scratches quickly appear on it, as a result of which visibility is reduced.

Plexiglas is widely used in medicine and aviation. It owes its popularity to its high strength. If it is destroyed, it is without fragments. Disadvantages include poor resistance to solvents and other chemicals.

Polycarbonate is another option for safety glasses. It does not fog, does not scratch and is lightweight. These glasses are stronger than the other two options, but also more expensive.

Design features of safety glasses

You can divide all existing safety glasses into several groups. The distribution occurs according to the type of material, design features and coverage area.

By lens material

Several materials are used to create protective glasses lenses. The most common of them are:

  1. Mineral glass. It has been used since the days of the USSR. The main advantages of the material are its high light transmittance and resistance to light impacts (damage, chips, scratches). The main disadvantage is the fragility of the product and the possibility of injury from chips.
  2. Organic glass (plexiglass) and plastic. The ability to transmit light of these materials is lower than that of mineral glass, but they are much more flexible. This allows you to withstand fairly strong impacts, and in the event of breakdowns, fragments practically do not appear. But due to a large number of scratches on the surface, the material may become matte, which will make it unsuitable for use. Therefore, the service life of glasses made of organic glass and plastic is not so long. Also, these materials are easily destroyed when exposed to chemicals and at high temperatures (200 degrees).
  3. Silicone. This material is the most flexible of all listed. It can easily withstand even very powerful blows, but does not cope well with minor damage. Silicone also quickly deteriorates when exposed to high temperatures (sometimes it can withstand up to 300 degrees, but most often it begins to lose its properties at 200). The surface becomes cloudy over time, so the service life is also quite short.

Some expensive models use combination lenses. In them, several materials alternate in layers.

By way of putting on

There are also differences in how glasses are attached to a person’s head. You can put them on yourself in one of two ways:

  • Classic with temples. When purchasing this model, the first thing to look at is the possibility of adjusting the arms. It is also necessary to take into account that during active work the glasses may fall or simply move out of place. This can create dangerous situations while performing tasks.
  • Sports. Such models are attached with a wide elastic band that goes around the head.

Some modern glasses provide two methods of fastening at the same time. If a special mask is provided for the work, then the fastenings can be supplemented with a small braid passing through the middle of the head.

According to the size of the protected face surface

There is no official classification of glasses on this basis. But they can be divided into several groups conditionally:

  • Only the eyes themselves with a small space around them are protected;
  • glasses overlap the eyes with part of the adjacent side of the face;
  • The entire face is covered with a mask or shield.

There are a huge number of models on sale now. They can either limit or increase the area of ​​protection of the nose, bridge of the nose and other parts of the face.

By size of review

There are also several subtypes of glasses with different viewing angles. They can significantly reduce or expand the operator’s angle of view:

  1. Additional lenses. These details are located on the temples of a person; they act as an addition to the central part of the lens of the glasses. With their help, it is easy to see objects with “lateral vision”.
  2. Curved shape. These models do not have additional transparent elements, but thanks to their semicircular shape they are able to expand the viewing angle to the sides.
  3. Cuts in the arms. These parts are slots in the side. They slightly expand the view, but do not prevent additional dust and foreign objects from entering the eyes.
  4. Wide transparent temples or frames. This subtype is made entirely of one material. If they are made with a frame, then the eyes receive additional protection from debris from all sides.
  5. Front view only. This type is equipped with the most modest visibility. It protects the eyes from all sides, but reduces the ability to see from the side.

Safety glasses for working with an angle grinder are divided into several groups. For example, they differ in the color of the lenses, the ability and method of ventilation (to reduce fogging), and tightness. For people with poor vision, it is allowed to use their medical model for protection. In such a situation, remember that models with diopters are not equipped with additional side protection. They cost much more, but are not resistant to damage. Because of this, if you have poor vision, it is recommended to use safety glasses along with lenses, or wear a medical model underneath them.

Safety precautions

There are several types of protective equipment required when operating this device.

Individual protection means

A guarantee of eye safety when using an angle grinder is safety glasses . They have several varieties:

  1. Open type glasses. They resemble ordinary glasses for vision correction or sun protection, but have a denser structure and increased plastic thickness. These glasses protect your eyes from sparks and small fragments. Their disadvantage is their lack of protection from dust. When working with ceramics and stone, dust is generated that can cause eye irritation. In this case, the following type of glasses is suitable.
  2. Closed-type glasses. They fit tightly to the contour of the face and prevent dust from entering the eyes. They also protect your eyes from splinters and sparks. Some models have a ventilation system that prevents fogging of the inner surface of the lenses. This version of glasses will cost a little more, but it also has more advantages.

Glasses must be worn regardless of the nature of the material being cut or sanded.

Protective mask

Another safety device when working with an angle grinder is a protective mask .
It can be reinforced with a special mesh, which makes it stronger. This mask is much better than glasses, because it protects not only the eyes, but also the rest of the face. The main cause of injury is a split saw blade. Its fragments, flying at great speed, can injure not only the person working with the angle grinder, but also those nearby.

Principles of safe work

The presence of personal protective equipment undoubtedly reduces the risk of injury when using an angle grinder. But it is also worth remembering other safety requirements .

  • Protective cover. This device must be on the angle grinder. Some careless operators remove the protection in order to put on a wheel of a larger diameter, which is not intended to work with this angle grinder. Sometimes the casing is removed in cases where it is necessary to use the grinder at an awkward angle. Such actions are unacceptable. Of course, the protective casing does not provide 100% safety, but in most cases it will protect you from injury. Recently, the protective cover for angle grinders has received a useful modification. It's called a dust extractor. From the name it is clear - this device helps direct dust particles in the opposite direction from the operator, which greatly simplifies the work.
  • Hand protection. To prevent sparks and hot metal particles from coming into contact with the skin of your hands, it is recommended to use special welding gloves. Small sparks hitting the skin do not cause obvious pain. But when a large burning particle hits, it causes severe pain. At this moment, the hand may shake, thereby creating a traumatic situation. Gaiters will help prevent hot metal from getting on your hands.
  • Selecting an abrasive wheel. To work with an angle grinder, you should only use a wheel that is suitable for it. If you use a circle with a diameter larger than expected, it may break without even touching
  • with the cutting object. The fact is that different models of angle grinders have different speeds, and abrasive wheels have different speed resistance.
  • You should also not use wheels with visible external defects, such as chips, deep scratches or cracks.
  • It is forbidden to install a disk on the grinder for sawing wooden products. Firstly, it is dangerous - the saw blade may encounter a knot, which can cause the tool to be torn out of your hands. Secondly, the disk will very soon become unusable, because it is not adapted to such a load. The speed of a circular saw is much lower than that of an angle grinder.
  • Sawing object. If the element being processed is small in size, you need to secure it with something. The best option for this would be to use a vice. It is strictly forbidden to saw the product with one hand while holding it with the other. In this case, the sawing element may be torn out of your hands.

If the product is large and installed motionless , it is necessary to ensure that the abrasive disc does not bite. General rules:

  1. Always unplug the angle grinder when replacing a blade. This is to prevent accidental startup.
  2. When choosing an abrasive disc, give preference to a trusted manufacturer.
  3. When working, make sure that the power cord is kept away from the sawing wheel.
  4. When using an angle grinder, avoid the possibility of hair and clothing getting wrapped around the rotating disc.

Beware: Bulgarian! Existing remedies

Personal protective equipment must be present, as shavings, sparks and other elements that can harm health are constant companions. To avoid this, people have come up with the simplest rules and means of protection that will help make work comfortable and safe.

Glasses

Since scale and sparks have a complex flight path, they can easily get under glasses or a mask, so you need to think about protecting your eyes before starting to work with an angle grinder.

Mask

A properly selected mask is a more reliable means of protection than glasses, since it covers and protects the entire face, but you should pay attention to many criteria. Nowadays, the manufacturer is trying to save significantly on the production of such masks, and the quality and level of protection suffers greatly as a result.

Nowadays, the manufacturer is trying to save significantly on the production of such masks, and the quality and level of protection suffers greatly as a result.

The danger of working with an angle grinder is that the grinding disc can break off the mount and fly into the worker, and such a mask should stop the disc and fully protect the user’s face.

Many are accustomed to thinking that instead of a special mask, a “turner’s shield” can be used, but this opinion is erroneous, since such a mask is designed to protect against small chips and minor scale.

Mittens and gloves

An equally important element of protection. During operation, your hands are close to the disk, so reliable protection from sparks, scale, chips and splinters is required.

There are cotton construction gloves, specialized gloves made of rough leather or those with a rubberized base.

Also, if available, you can use leggings for welding work; they are made of durable suede and are designed specifically for such conditions. They have a high base that will protect not only the palms, but also the forearms.

Rules for cutting with scissors

When cutting sheet metal, it is important to consider the following operating rules and safety regulations:

  • It is possible to cut metal sheets of small thickness without any additional design solutions. To do this, you need to lay the metal on a workbench, fix one end with your hand, and cut the other according to the markings.
  • When cutting metal of considerable thickness, you should clamp one handle in a vice, in this case there will be a reliable stop. The pressure on the knives increases, and therefore you will be able to cut large sheets.
  • If you are cutting wire with metal scissors, you must use gloves made of thick material.
  • In order to protect your eyes from mechanical damage, it is important to wear at least glasses, but it is better to use a face mask.
  • Fix the separated pieces of wire when cutting towards the workbench.
  • You can give a piece of wire or sheet to other people only with the sharp ends facing you; this is done in order to protect the other person from accidental cuts.


We hope that you have carefully read our article, which means you can choose good metal scissors without any problems. All the best!

Before you start working with an angle grinder

When starting to work with any power tool, including an electric grinder, you need to concentrate as much as possible. You can't take on a job without being prepared. Fatigue is the first cause of negligence, which can lead to unpredictable consequences.

The presence of a protective casing and glasses are mandatory conditions, without which you cannot begin work. Sparks, flying particles of abrasive material, metal and scale always accompany any process in which an angle grinder is used. If such particles get into the eyes, serious health problems can occur.

It is advisable to use glasses or a mask with a closed design that replaces them. The spread of sparks and metal shavings occurs along an unpredictable trajectory and you can never predict whether they will get under the mask or not if it is an open type. It’s good if the mask has a protective mesh, since impacts from fragments can be so powerful that they can pierce plastic.

The presence of a casing on the tool provides the first protection that stands between a person and a rapidly rotating cutting wheel. Moreover, the destruction of the latter is a frequent occurrence. Most people who regularly use an electric grinder have repeatedly encountered this problem. Most often, the circle is destroyed when a metal workpiece becomes jammed in the resulting slot.

The main purpose of the protective casing is to prevent the emission of sparks and other particles towards the person using the angle grinder. In this case, the casing is secured in such a way that it does not rotate spontaneously or shift to the side. And no matter how much many builders would like to remove the protective casing to make working with the tool easier, doing this is strictly contraindicated. Neglecting this rule can lead to unpredictable consequences for human health.

Safety precautions when working with angle grinders

Compliance with solid waste is the key to safe work and high-quality results without negative consequences for health and life.

  • Using a protective shield when working with an angle grinder is an important component of the process that cannot be ignored;
  • In addition to the mask, before work, put on protective gloves and a suitable suit (preferably a special one) to protect not only your face, but also the rest of your body;
  • For each type of material, use only a specially designed disc;
  • Check tool fastenings and guards before starting work;
  • Before work and after changing the attachment, check the tool at idle speed;
  • Work in a comfortable and stable position;
  • The most dangerous thing when working with an angle grinder is the rupture of a disk rotating at high speed. Splinters can cause fatal damage, so it is extremely important to purchase high-quality protective materials and use the machine in accordance with safety precautions.

Under no circumstances remove the protective casing from the angle grinder to lighten the weight of the tool!

Remember, life and health are the most important. Do not neglect safety precautions and use protective equipment to avoid damage to the skin and eyes.

Pros and cons of glasses and masks

When thinking about what to choose – glasses or a mask – you need to pay attention first of all to the features of the repair work. So, glasses have the following advantages:

  • low cost;
  • good degree of protection;
  • large range of products;
  • Ease of use.

Glasses are suitable for work in which the likelihood of falling into fragments is minimal. They do not protect the entire part of the face, but only the eyes - this is their main drawback.

However, masks have other advantages:

  • the ability to protect the entire face;
  • many modifications and additional means of protection (fasteners, belts, rotating mechanisms, protective shallow stacks, etc.).

However, masks also have their drawbacks. It is problematic to work in them for a long time, since most of the face is covered, which will lead to sweat. The masks are equipped with holes for ventilation, but when working at temperatures they are unlikely to save you. And the cost of masks is more.

Will regular anti-dust masks protect against welding aerosols?

Dust respirators provide respiratory protection from various types of dust, dusts, powdered fertilizers, acids and alkalis. These types of PPE do not perform the full range of protective functions for the welder . Therefore, you should not choose them as a replacement for special respirators. This may result in injury or illness. Anti-dust half masks are suitable for construction work, for example when cutting concrete or sand-lime brick.

How do safety glasses work?

Most models of safety glasses consist of two elements:

  • eye protection;
  • securely attached to the head.

The design may differ in the presence of ventilation elements. They are necessary to prevent glasses from fogging up from the inside during prolonged use. Fasteners, linings, and seals are also allowed, which make the use of these products more versatile and comfortable.

The main task of protective equipment is to protect your eyes from sparks, metal shavings, scale, dust and suspensions that form while working with an angle grinder. Also, the purpose of the glasses is to create a barrier between the instrument and the eyes in case of destruction of the first.

The principle of operation of such glasses for angle grinders differs from their type. If the glasses are open, their effect is reduced to creating an additional protective screen made of durable plastic. At the same time, they leave gaps between the edge of the glass and the face.

Small particles of dust and smoke can get into these gaps. Open type products are characterized by low quality of protection. Their price on the market is low.

Closed-type devices have a more complex structure. They are a device that fits tightly to the face and reliably protects it from dirt. Their protection is more reliable.

The main disadvantage of such glasses is that the inner glass fogs up. To prevent this from happening, manufacturers apply a special coating to the inner glass. Installation of direct and indirect ventilation is also provided. Air supply partially solves the problem of glass fogging.

Among the open and closed type safety glasses, there are models with polarizing coating and light filters. Their operating principle is to protect the eyes from harmful radiation of different wavelengths. On the market you can find glasses in yellow, brown, black, gray, and pink colors. Depending on the shade, they transmit one or another light spectrum.

Varieties and characteristics

They are distinguished by the degree of openness and transparency.
The second indicator should be taken into account when work occurs with an object that is too bright or with dangerous radiation. Transparency can be lower than 95% without obstructing visibility. According to the degree of openness, glasses are:

Open - in appearance they resemble regular glasses or sunglasses. A cheap model, sometimes equipped with side corner protection (from the side of the temples), rests on the arms. They have minimal protection against small particles escaping from under the grinder, but do not prevent dust, smoke or harmful fumes from getting into the eyes. As is the case with a regular instance, the open type must be selected individually

It is important that the size and shape fit the wearer perfectly, otherwise the glasses will constantly fall off and get in the way.

Closed is a comprehensive block against large or small particles, dust and chemical fumes. They are attached to the head using a strap or stretchy rubber band. There are models that are a combination of glasses and a mask, which provides complete or maximum possible face protection.

There are series without ventilation, but with a special coating that will prevent the glasses from fogging up. When cutting or grinding hard or particularly hazardous materials, the closed type is preferable, although more expensive.

As for ventilation, it can be direct or indirect.

The first type is the direct presence of through holes or slits in the protective equipment. It is the most economical option and is also suitable for simple types of work no more than several times a month.

The second is valves with built-in filtration of dust, smoke and fine suspended matter. Valves are much safer than direct ventilation and are designed for maximum protection, but increase the cost of the product.

Review of the best safety glasses models

Let's look at the options for the best models. The leaders in this production are the manufacturers DEWALT, POCOM3 and UVEX.

For open models we turn to POCOM3 and UVEX.

POCOM3 HAMMER ACTIV: open type, models are available in three versions: transparent; with darkened lenses; with lenses that increase contrast. Wide view, chemical resistant plastic, protects against particles (120m/s). The cost is approximately 170 rubles. Since the price-quality ratio is most optimal in models of this brand. Customer reviews indicate that the glasses themselves do not interfere during work, although they reliably protect from dust.

UVEX PHEOS and I-VO are popular options for open eyewear from the global market leader in PPE.

These models are available with lenses of different colors - to suit certain needs. UV filter, protects against particles (45 m/s) and chemicals. The price varies 500-800 rubles.

Next, let's look at closed-type glasses. Buyers named the main advantage of such models as extensive adjustment options to suit the user’s size.

But there is also a minus; reviews indicate a flaw in the “anti-fogging” function. In addition, when choosing closed-type models, a problem also arises for people with glasses, because they also need to wear safety glasses over optical lenses.

There are two options here: either buy such models of safety glasses, where the lenses plus a corrective one, or choose spacious models with the ability to wear glasses under them.

UVEX ULTRAVISION – closed-type glasses with impact-resistant lenses and ANTIFOG anti-fog protection. Indirect ventilation. It is possible to wear over corrective glasses. Protection from dust and particles (120m/s) as well as from chemicals. substances. Adapted to attach an optional protective face shield. The cost varies from 900 to 1400 rubles.

Protective shields

Special shields, or masks, for working with an angle grinder seem to be more reliable, but their cost is higher. Professionals prefer this category of protective equipment, because they protect not only the eyes, but the entire face. Masks come in different types and are made from different materials, which affects their appearance and cost.

The masks are attached using special belts or other fasteners and are held tightly on the head; the protective glass protects against the ingress of scale and dust particles and materials. Some shields have a visor that protects the forehead. In addition, shields are made with a special fine mesh - this is additional protection, including from damage to the mask itself during operation, which increases its service life. Overall, a face shield is more durable than regular glasses.

Care and storage rules

Most models, even made from durable material, quickly wear out and fail. Therefore, before each use, you should carefully inspect the frame for damage. If there are severe chips, deep cracks and scratches on the surface, and the elastic band is stretched and loose, it is better to purchase a new model.

To remove adhering dust and dirt, the surface should be periodically wiped with a piece of damp cloth. The hardware store sells special material impregnated for disinfection. It is better to store the protection in a special case that protects it from damage.

To work with an angle grinder, special safety glasses are used. They protect the organs of vision from foreign objects and dust. There are many models on sale, among which it is not so easy to choose the right glasses. When purchasing, it is better to rely on the material of manufacture, price, ease of use and other characteristics. The more carefully you care for your safety glasses, the longer they will last.

Traditional methods for preventing glasses from fogging

Folk recipes are simple and accessible, but have their own nuances. Here are the most popular:

In this article

  • Traditional methods for preventing glasses from fogging
  • Tips for caring for foggy glasses
  • Professional anti-fog glasses
  • A piece of solid soap. The lenses of the glasses are rubbed with a dry piece of any scented soap, then the applied mass is evenly distributed over the lens with a soft cloth, while drying the glass (minus - it is difficult to apply an even layer, so the view will deteriorate on rainy days);
  • Shampoo. Add warm water to the hair wash in a ceramic bowl in a 1:1 ratio and mix thoroughly until a homogeneous mass is obtained; then the solution is applied to the glass with a piece of clean soft cloth, and wiped dry with another dry cloth (this may leave barely noticeable rainbow stains, which will contribute to the appearance of glare and make it difficult to see);
  • Spray for car windows. It is enough to spray it on the inner surface of the glasses lenses and wipe dry (you should remember that auto chemicals are not intended for people; it is undesirable to use such dangerous products);
  • Glycerin (liquid). A soft cloth is generously moistened with the solution and the glasses are thoroughly rubbed on both sides, then the glasses should be allowed to dry naturally, and then polished with a dry soft flannel cloth (this method of combating glass fogging takes a lot of time);
  • Toothpaste. Squeeze out 1 pea on both glasses from the inside and rub thoroughly with a napkin; after drying, the remaining paste is removed with a soft cloth (however, it is very difficult to clean glasses of dried toothpaste without damaging the surface of the glass);
  • Shaving foam. Apply to glass with clean fingers and wipe with a dry cotton pad until completely dry (this method is the least effective due to the texture of the foam being too soft).

All folk remedies are free of charge, because they are available in any apartment, but the above methods are quite time-consuming. Various detergents often have to be reapplied to the glass, after first removing the previous layer of soap or shampoo. It is also inconvenient that mixed solutions of detergents and water cannot be stored; the ingredients will need to be mixed in accordance with the proportions before each application. Folk recipes are quite applicable as a one-time use when the glasses in your glasses fog up and you need to quickly take at least some action.

Don't look at the bright light!

Eye protection during plasma cutting is a question that interests many. Let's look at the problem in more detail. When cutting, a plasma arc, like any electric arc, emits a wide range of electromagnetic radiation, which goes all the way: from infrared light (passing through the visible spectrum) to its ultraviolet range. The electric current during plasma cutting can be very intense, ranging from 100 to 800 Amperes. It goes without saying that looking at the arc can easily cause eye damage. If a worker's retina is exposed to bright light for a long time, the consequences may be more serious. How to avoid this?

Recommended eye protection for plasma cutting

There are several important, good sources that have standards and recommendations that any good welder should know. These include OSHA and ANSI standards, as well as OST 5.9823-80 “Electric welding works. Safety requirements".

Let's consider foreign standards. OSHA is the US Federal Occupational Safety and Health Agency. Their fact sheet, “Protecting Eyes from Radiant Energy During Welding and Cutting in Shipbuilding Operations,” has guidelines for welder eye protection citing data from ANSI (American National Standards Institute). The eclipse degree numbers refer to safety glasses or welding helmets. The higher the number, the darker the glass.

ANSI and the American Welding Society (AWS) have published an even more detailed table, “Safety in Welding, Cutting, and Related Processes (ANSI Z49.1: 2005).”

In both cases, the guidelines suggest a rule of thumb: “Start with the shade that is darkest to show the weld area. Then we move to a lighter shade that gives enough representation of the welding area without going below the minimum.”

ANSI recommendations for SMAW, GMAW and FCAW welding are in the shade range with shade number 10 - 14. How does this apply to a welding operation? When welding, you basically stand and look at the welding area through your helmet as usual, and you can manually operate the welding torch, which is just a few centimeters from your face.

But the operation of a CNC machine is slightly different:

  • the operator is much more likely to be further away from the arc;
  • the welder must move around, so he must be able to clearly see his surroundings (this is relatively dangerous in a welding helmet);
  • the operator must have visual ability to control the machine while the arc is on;
  • The welding arc moves, so the operator will not always be able to see in its direction.

Where can I buy

Manufacturers, authorized representatives, suppliers and specialty stores offer a wide range of respiratory protection devices. American factories occupy the leading position in this segment. In addition, performers are provided with a large selection of products from Russian enterprises.

You can familiarize yourself with the proposed list of respirators and other products for welding in the “Where to buy electrodes” section. Trading companies sell goods at retail and wholesale. Organizations actively cooperate with individuals, individual entrepreneurs and enterprises of various profiles.
