Today you can find many personal protective equipment, and protective face shields are no exception. It is necessary to have such equipment available at any construction and production facilities.
At the same time, GOST standards for protective face shields are the very first criterion for choosing equipment.
Appointment
A good face shield is a reliable protection of its user from various damages to eyes and face skin.
Using this equipment, you will protect yourself from such misfortunes as hot sparks, splashes of liquids, small objects, as well as some alkalis and acids. Some modern models can protect workers from various types of radiation.
It is very important to consider the convenience of the shield, because the level of its safety depends on this in many respects.
Protective face shields are most often used in such areas of human activity:
- automobile and mechanical engineering;
- construction and repair;
- chemical industry;
- oil and gas production;
- metallurgy.
Materials used
Modern protective face shields are made of high-strength materials that wear out for a long time and protect the human face from various types of damage. In addition, the right technology allows equipment to withstand large temperature differences, which allows them to be used anywhere on the globe.
The most commonly used material is polycarbonate, which refers to heat-resistant polymers. This material is in great demand, as it is able to protect the face even from a short-term temperature increase of up to one hundred degrees Celsius.
Very often, protective face shields are made of a material such as non-combustible plastic. This material is able to reduce the intensity of warm radiation by fifty percent. At the same time, high-quality plastic is able to perfectly protect the face from various types of damage due to its strength.
The material most often found on the shields of inexpensive models is organic glass. This material, just like the previous ones, is able to protect the worker from mechanical and chemical influences.
A very important property of all three shields is their dialectic. That is why the protective face shield for an electric welder can be used for work with electrical installations.
Types and characteristics
There are several types of face shields:
- protective equipment of a universal type;
- devices mounted on a helmet;
- special shields attached to the helmet, for the possibility of welding;
- equipment for electric welders.
Universal face shields are designed for all types of work, during which the worker needs to protect his face from mechanical damage.
The shield, which can be attached to the helmet, is most often used in production, as well as for construction work. This device is very convenient, as it is easy to put on and take off if necessary.
Welding guards can be attributed to a special category. The safest are equipment that have a solid shape. This option is considered the safest, moreover, it makes it possible to independently adjust the degree of dimming.
When choosing a shield, be sure to pay attention to the size of the viewing window. The bigger it is, the better.
How to make the right choice
The modern market offers a huge amount of eye protection. The protective face shield can be an excellent barrier, provided that it is selected correctly.
Pay attention not only to the external characteristics and purpose of this device, but also to personal comfort. In this case, it is very important and no less affects your personal protection.
Pay attention to such parameters that should be right for you:
- what material the viewing window is made of;
- is there a headband adjustment system;
- what material the inspection screen is made of;
- weight of equipment;
- are there convenient accessories available that can facilitate your work.
Rules of operation and storage
Please note that each personal protective equipment has its own period of use. Depending on the conditions of use, the life span of your protective shield may be shortened. For example, workers associated with the chemical industry or hazardous industries should change their face shields as often as possible.
However, with the right condition and storage, you can significantly extend the life of this device. Experts recommend storing it in a special protective case.
Be sure to read the device care instructions specified in the manufacturer's instructions. This can significantly extend the shelf life of protective equipment and save your life.
