Many construction professions require the availability of personal protective equipment. These can be closed and open glasses, masks, screens and other special devices that do not allow foreign bodies, flying particles, smoke, sparks, liquids, and chemicals to enter the eyes. The means used must be fully consistent with the specific type of hazard. Sometimes it is worth completely covering your face from possible injury, but there are times when glasses are enough.
a brief description of
Safety glasses are an integral part of production processes, laboratory research, and are constantly used during construction work. They protect the face from splashes of hot metal, welding, droplets of aggressive liquid, infrared and ultraviolet radiation. In addition to glasses, there are also screens that look like a plate, rounded at the edges, with a head mount. There are a great variety of devices. They can have an elongated shape to protect the neck, and additionally be equipped with a plastic visor to hide the frontal part.
Impact-resistant materials are used in the manufacture of products: organic glass, polycarbonate and others. They are not afraid of chemical and mechanical damage, withstand significant temperature changes, providing one hundred percent visibility.
Some difficulties may arise when using personal protective equipment:
- field of view may be limited;
- Prolonged wear may cause discomfort;
- fogging of glass when working in hot shops.
The best manufacturers are trying to produce popular models taking into account the increased requirements for their operation and ease of use in any conditions.
In the production of face shields, modern high-tech equipment and high-quality and reliable materials are used that meet all safety requirements. A technology is used that makes it possible to use structures in any climate.
A distinctive feature of the product is its low weight to completely eliminate the load on the neck and head. The shield should not cause irritation or allergies during prolonged use. The best popular models have soft hypoallergenic pads for wearing comfort. Durable and high-quality fasteners do not put pressure on the head.
The screens are 100% transparent and completely eliminate optical distortion, which makes it possible to increase productivity, improve the quality of products, and avoid eye fatigue during long-term work. Some models provide the ability to wear additional protective equipment: respirators, headphones, and so on.
How medical devices work
Medical safety glasses are devices that are designed to protect the eyes from particulate matter, chemicals, or harmful radiation during medical procedures.
They found the greatest applicability among surgeons and dentists.
During surgery or treatment, glasses protect against:
- splashes of biological fluids, used medications, chemical compounds;
- flying fragments;
- dust and harmful cleaning compounds and their fumes during the treatment of premises.
Medical protective devices with light filters are used when processing metal, ceramics or plastic in the manufacture of dental crowns or prostheses, in the case of laser procedures.
During manufacturing, medical glasses are immersed in a special composition that reliably protects the inner surface of the glass from fogging. Models of medical glasses are smaller in size and lighter in shape.
They are divided by type into closed and open in the form of a mask. Helioprotective glasses are also available. They have a light filter that does not allow the blue part of the light spectrum to pass through. The glasses of these glasses are made in orange or brown.
Thanks to their universal shape, medical glasses can be worn over regular glasses to correct vision. This combination does not cause discomfort.

Scope of application
There are certain types of activities that require mandatory protective equipment. These include:
- Laying communication networks.
- Carrying out finishing work.
- Processing of wood, stone and metal.
- During the construction of any objects.
- In the mining industry.
- Cleaning of territories and premises.
- Carrying out work involving the use of solutions and chemically active substances.
- Welding work of the main and auxiliary plans.
- Oil and gas industry.
- Metallurgy.
- Heavy industry.
- Mechanical engineering.
- Work where biological risks are present.
- Area of management and logistics.
What are there
There are many types of PPE. In order to avoid mistakes when choosing, you need to seriously understand this issue. Based on design features, the following types are distinguished:
| Types | Description |
| Open | Side and front eye protection. |
| Closed | Reliably protected from all sides. Fits tightly to the face. Can be worn over prescription glasses. Devices are available with length-adjustable arms and a special-purpose shield. |
| Sealed | Prevents liquids and gases from entering the eyes. |
| Double | Models have double glass. They are distinguished by reliability and increased strength. |
What should you pay attention to when purchasing a product? On its properties. Available models:
- Metallized. Made of glass. Serve to protect against electromagnetic radiation. An integral attribute of workers at electrical installations.
- With a light filter. Able to filter light radiation in the visible spectrum. Not a single welder can do without them.
- Reinforced. Prevents the entry of solid particles. They are extremely popular among welders, masons, tilers, carpenters and representatives of other professions whose activities involve processing all kinds of materials.
- With a special coating that minimizes fogging and makes them impossible to scratch.
These properties can be combined, resulting in reliable products that prevent all kinds of threats. Devices are available that can protect both the eyes and the face at the same time. They are divided into the following types:
- opaque (protect from bright light, splashes of molten metal, sparks);
- transparent (do not impair visibility and prevent the penetration of solid particles).
Material of manufacture
Polycarbonate is considered to be the most durable. It is characterized by high heat resistance, shock resistance, and qualitatively protects the face from solid particles, metal splashes and short-term temperature increases of up to 100 degrees. They have such qualities as dielectricity and are used when working on electrical equipment. Completely transparent, does not create optical distortions.
Polystyrene has less transparency than polycarbonate. Ideal protection against splinters, hot splashes, solid particles, sparks. Used by professionals during repairs and construction work.
Shields are produced from non-flammable plastic. They are able to reduce the thermal impact rate several times. Heat-resistant shields help reduce thermal radiation. Mandatory attribute for welders. The devices are additionally equipped with a light filter. They are sometimes called welding glasses.
Structures made of organic glass are considered budget-friendly. They will protect against dust and solid particles. They are resistant to mechanical damage. Not afraid of chemical exposure.
Manufacturers produce products from metal mesh. Fine-mesh material is not able to prevent aggressive liquids or hot splashes from getting on your face, but it will completely protect your eyes from flying fragments and solid objects.
Mounting method
Models are available with two mounting methods:
- Nagolovnoe. It is equipped with a system of belts that hold the screen on a person’s head. There is a special device, thanks to which the shield is raised and lowered, as well as fixed in the required position.
- With helmet mount. Special adapters are provided to allow you to securely attach the product to your helmet. A lifting and fixing device is installed that lowers, raises and fixes the shield in the required state.
Marking of safety glasses according to GOST
Safety glasses are double marked. One is applied to the frame, the other to the lens. Before choosing a product, you should familiarize yourself with the encrypted information. It will help you decide on the most suitable model.
| Explanation of markings | |
| 2- | Only products with glass that is protected from UV and IR radiation are marked. This is a gradation code that defines light filters. |
| X | The symbol identifies the manufacturer. This can be one or more characters. |
| 1 (2, 3) | Belonging to the optical class (except for cover glasses). |
| S | This is the designation for mechanical strength in some types of glasses. Explanation of symbols: S – increased. F – the product can withstand low-energy impact. B – resistance to medium-energy impact. A – withstands high-energy blows. Products without symbols indicate minimal strength. |
| 8 | Resistance of the product to thermal processes (short circuit arc radiation, etc.). |
| 9 | This is an indicator of the adhesion of molten alloy particles and resistance to their penetration through glass. Available on select models. |
| K | Resistance to surface destruction under the influence of fine aerosols. |
| N | Resistance to lens fogging. |
| R | The marker means increased glass reflection. |
| O(V) | Indicates original glass (O) or replaced lenses (V). |
Certified products always have a marking indicating the mark of conformity - GOST R12.4.230.1-2007 (or EN 166-2002).
The marking on the product must be readable and durable. The inscription is placed on the lenses so that it covers the minimum area of the field of view in the permissible zone. Markings are not placed outside this part so as not to interfere with the work process.
The number is placed on the frame and lenses. If these parts are one piece, then the full marking is located on the frame.
How to choose
Selection criteria vary depending on the area of use of the structure. Products may differ in functionality, design, viewing angle, average price, and manufacturer. There is no question of where to buy the products. You can visit specialized retail outlets, where a professional manager will introduce you to new products, tell you what they cost, and recommend which company is better to purchase the product.
You can order products online in the online store. It is advisable to first familiarize yourself with the ratings of quality products, look at reviews, and recommendations from experts. According to buyers, a good option is to receive goods from China using AliExpress. The only drawback of this purchasing method is that there is a high probability of receiving a defective product or a low-quality fake.
Which one is better to buy depends on many factors. But there are uniform requirements that apply to all personal protective equipment:
- Lenses must withstand an amplified impact of 1.2 J or a single impact with kinetic energy of 0.6 J.
- The weight of the product should not affect productivity.
- Completely harmless and safe for humans.
- Prevents fogging and scratches.
- Sit firmly on your head, do not dangle or fly off during sudden movements.
- Removal is easy and simple.
- The dimensions of the glass should in no way interfere with the view.
Glasses can be tinted and transparent, with indirect and direct ventilation, with or without additional functions, differ in appearance, color, and manufacturer. Direct ventilation is more popular, but such products are not able to protect against dust, and therefore do not guarantee the ability to safely plan, drill, process metal and wood.
Reusable and disposable
Depending on the service life, disposable and reusable respirators are distinguished. Half masks of the first category must be disposed of immediately after the first use, since the filter attached to the model becomes clogged, and it is not possible to change it.
Reusable respirators can withstand 2 or more work shifts. Long service life is ensured by the presence of replaceable absorbers. Replacement should be made when the performer begins to experience difficulty breathing due to contamination of the filter. After changing the absorber, the mask is ready for further use. Professionals who constantly use protective equipment need to choose reusable models
Home craftsmen and performers of periodic work should pay attention to disposable respirators; they have a more affordable price. The level of welder reliability from harmful factors does not depend on the service life of the respirator
Therefore, when choosing the type of masks, you should take into account the frequency, intensity and level of complexity of the work.

Tips for care and storage
All personal protective equipment has a limited service life. It is installed by the manufacturer and is indicated on the packaging. But in order for the structure to serve as high-quality protection over a long period, it must be properly cared for. It is worth considering that the product constantly interacts with high temperatures, solid particles, molten metal, chemicals, dust and gases. Due to the significant load, it can quickly fail.
The basic storage rules are as follows:
- Store in rooms specially designated for this purpose.
- Avoid direct sunlight.
- Prevent from mechanical damage.
- Avoid interaction with negative factors.
- Use special cases for storage.
- Regularly check for functionality and reliability.
- Visually inspect the screen for cracks, scratches, chips and other damage.
- Do not leave near heating devices.
- Do not clean with aggressive agents.
Eye hazard
Flying sparks, metal and stone filings, due to their low mass, have insignificant kinetic energy, but sufficient to harm the health of a careless operator. A large piece of an exploding cutting wheel, in accordance with the law of physics “mass times the square of the velocity divided in half,” can have a kinetic reserve comparable to the muzzle energy of a small caliber weapon
A large piece of an exploding cutting wheel, in accordance with the law of physics “mass times the square of the velocity divided in half,” can have a kinetic reserve comparable to the muzzle energy of a small-caliber weapon.
A properly installed guard directs the flow of sparks and microparticles away from the operator, instilling a sense of safety, but obstructing visibility and hiding cut marks. Any careful attempt to look behind the casing, any ricocheting fragment - and...

Tips for choosing the right glasses for working with an angle grinder
When choosing the products in question, it is important to pay attention to some important points. These points include:
- The material from which the product is made. You need to choose models that have a high degree of protection. The presence of glasses on the nose when working with an angle grinder does not mean that the person is completely safe
- Availability of auxiliary protection against ultraviolet radiation. If your job requires you to work every day in the sun with an angle grinder, then it won’t hurt to purchase safety glasses with a special coating against ultraviolet radiation. Models called “Chameleon” are popular.
- Ventilation. If you prefer a closed type of product, be sure to make sure that the devices are equipped with ventilation. If the product does not have such a function, then you will need to remove the glasses very often to remove condensation from the inside of the glasses
No one can take care of a person’s own health except himself. In order to work with such a dangerous tool as an angle grinder without injuries or other incidents, you need to take a serious approach to the choice of protective equipment. If you do not follow safety rules, even an experienced specialist can get injured.
