Currently, the market for specialized clothing is replete with various personal protective equipment.
One of the most popular categories is protective face shields. They are mandatory for workers at production and construction sites.
The requirements for the condition of these protective equipment are strictly regulated by general safety rules in accordance with GOST standards.
Purpose of use and their purpose
Modern face shields are reliable means of protecting the worker from various damages, that can be encountered in the process of labor activity.
Due to use, hits in the face area are excluded items such as hot sparks, splashes of non-acidic liquids, solids, chemicals, acids, alkalis. Separate models protect against radiation. The convenience of the guards is a priority for the user, the safety of the worker largely depends on this indicator. Inconvenience, on the other hand, can lead to traumatic situations.
Protective face shields are widely used in the following areas:
- Building;
- Gas and oil industry;
- Ferrous and non-ferrous metallurgy;
- Chemical industry;
- Machine and car industry.
Regarding professional duties, where is the application personal protective equipment required, then their list is very wide. Guards are used in painting, plastering, welding and numerous repair work.
In production, where there are blast furnaces and steel furnaces, the wearing of these funds is also mandatory. In the latter case, there is a separate regulation of requirements for the use of individual funds patronage, which should be suitable for certain standards.
Production materials and production technology
All modern guards are made of various high strength materials, which are resistant to various types of wear, to mechanical and shock loads. Production technology allows products to withstand significant temperature differences. Shields can be used in various climatic conditions.
Various heat-resistant polymers, for example, polycarbonate, can act as a material. It is able to protect the face even from short-term strong heat. to temperatures above 100 ° Celsius.
Depending on the manufacturer, the maximum heating rate may vary. average temperature makes about 130 ° C.
Another common option for raw materials used in production is it is nonflammable plastic. Its features are to reduce the intensity of heat radiation by half. Plastic is able to effectively protect the face from significant mechanical stress, since it has very high impact resistance.
The material that is most often found in budget options for protective face shields is organic glass or PMMA. In fact, this is a thermoplastic plastic, but manufacturers use various technologies that give the material not only resistance to shocks, but also to chemical influences.
A very important property of all three materials is their dielectricity, which makes it possible to use shields when working with electrical installations.
Companies supplying personal protective equipment to the modern market, use high-tech face shield manufacturing methods. This is due not so much to a high degree of competition as to the requirements for safety and comfort of use. The design of the products involves lightness and lack of load on the cervical vertebrae.
Screen glass has absolute transparency without the slightest optical distortion, so the eyes will not get tired even with prolonged use.
The production of polymers using organic synthesis and other similar technologies allows you to create materials that, with prolonged contact with a person’s face will not cause irritation even for allergy sufferers.
Manufacturing technology concerns not only glass, but also comfort in general. Inside most modern face guards are provided soft pads that allow you to ignore a foreign object, fixed on the head, and focus on work. Belts do not squeeze, however, very securely fix the shield.
Safety goggles are used in dentistry to prevent photopolymerization radiation from reaching the retina. Find out what glasses are here.
Types and characteristics
Personal protective equipment such as face shields, has several varieties, different in their characteristics. Currently, among the most popular products, several main types can be distinguished:
Universal guards are designed for all types of work where face protection from damage is required. They are excellent protection against small particles processed material, from splashes. The degree of protection against radiation and chemicals is determined by the material of the glass.

This variety is easy to mount, so it is used by specialists working in various directions. Such guards have an elongated screen, whose shape is somewhat “beveled” downward. The design significantly increases ergonomics, so you can freely rotate and tilt it with your head.
The screen additionally protects the neck and upper chest from high temperature and mechanical damage.
Helmet with a protective shield, most often used at construction sites and various industries. This protector is easy to take off and put on when needed. There are models with a special filter that allows you to do welding work.
Welding shields fall into a separate category. Professionals especially appreciate solid models that have a classic closed shape.
This is the safest option, since the characteristics of such products include, first of all, the presence of filters with the ability to manually adjust the dimming.
One more an important parameter is the presence of a large viewing window. Welding shields with helmet mounts are not much different in characteristics from the previous version.
It also has adjustable light filter and large inspection window. The difference lies only in the design. Such models are mounted on a helmet, which makes them convenient for specialists who do not always have to resort to welding for work. Direct protection radiation depends on the settings of the filter.
A properly selected face shield will become a means that can preserve health and, possibly, life.
Tips for picking up

Storage and operation
Every personal protective equipment has its own operational capabilities. Each manufacturer puts its own label with an expiration date, however, depending on the conditions under which it is necessary to work, the period may be reduced.
Chemical workers, welders, and other hazardous workers are forced to change personal protective equipment quite often. This is due to the constant loads on this PPE.
With proper care and storage, it is possible to extend the time. As a rule, manufacturers, in addition to the original packaging, also offer special storage covers.
If there was no such cover when buying, then it is worth it to purchase. If this is not possible, it is necessary to keep the product away from solid objects in order to avoid damage to the screen, even if the latter has a protective coating.
Any scratch can cause significant discomfort to the eyes.. Care for the shields should be carried out in full accordance with the recommendations of the manufacturer. It is very important not to forget about it after the end of each working day.
Selection by parameters:
At construction sites, glass-blowing factories, metallurgical plants, chemical concerns, to protect the eyes and face from flying particles, concrete dust, chips, splinters of solid materials, droplets of caustic substances, welding products, a protective shield is used.
