Guard For Working With Angle Grinder

Protective shields

To protect the eyes and face from sparks, particulate matter and chemical liquids, a protective shield is designed in production and in laboratories, on construction sites and in workshops.

The screen is a semicircular plate with two ribbons, frontooccipital and parietal. Their adjustment can be smooth or step to fit in size and securely lock the protection during operation. A plastic visor may be provided to protect not only the face, but also the frontal part of the head. In some models, the screen is elongated and serves to protect the neck.

Types of face shields

By type of mount

Head-mounted. a belt system holds a transparent screen on the worker’s head. The rotary-locking device holds the glass in the raised or lowered position.

With helmet mount. the screen is attached to the safety helmet with a lifting and fixing device that moves it up / down.

According to the screen material

From a metal mesh. such protective shields are a fine-mesh strong mesh and protect against large solid particles. Used at mining and forestry enterprises. Not suitable for protection against liquids, metal splashes, sparks.

From polycarbonate. transparent face shields are protective against impacts. Protect from solid particles, sparks and splashes of metal, electric shocks. They are used to service electrical networks.

Of polystyrene. durable, but not so transparent. Used in construction and repair work, protect from sparks, metal splashes, fragments, chips, etc.

What to consider when choosing a protective shield

Working conditions determine the maximum temperature: there are shields that can withstand up to 105 and 180 ° C.

Learning to choose the right face shield

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 the general safety rules in accordance with GOST standards.

Purpose of use and their purpose

Modern face shields are a reliable means of protecting the worker from various injuries that can be encountered in the course of work.

Thanks to its use, objects such as hot sparks, splashes of non-acidic liquids, solid particles, chemicals, acids, alkalis are excluded from the face area. 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:

  • Construction;
  • Gas and oil industry;
  • Ferrous and non-ferrous metallurgy;
  • Chemical industry;
  • Machine and car industry.

As for professional duties, where the use of personal protective equipment is mandatory, 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 the requirements for the use of individual means of protection, which should be suitable for certain standards.

Production materials and production technology

All modern guards are made of various high-strength materials that are resistant to various types of wear, to mechanical and shock loads. Production technology allows products to withstand significant temperature extremes. Shields can be used in various climatic conditions.

Various heat-resistant polymers, for example, polycarbonate, can act as a material. He is able to protect his face even from short-term strong heating to temperatures above 100 ° Celsius.

Depending on the manufacturer, the maximum heating rate may vary. The average temperature is about 130o C.

Another common option for raw materials used in production is non-combustible plastic. Its features are to reduce the intensity of heat radiation by half. Plastic is able to effectively protect the face from significant mechanical stresses, 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 that supply 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 there are soft pads that allow you to not pay attention to a foreign object attached to the head, but to focus on work. Belts do not squeeze, however, very securely fix the shield.

Types and characteristics

Such personal protective equipment as face shields has several varieties that differ in their characteristics. Currently, among the most popular products, several main types can be distinguished:

  • Universal face guards;
  • Guards with special helmet mounts;
  • Face shields with helmet mounts for welding;
  • Protective face shields for electric welders.
  • Universal guards are designed for all types of work where protection of the face from damage is required. They perfectly protect against the ingress of small particles of the 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 heat and mechanical damage.

    A helmet with a protective shield is 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, as the characteristics of such products include, first of all, the presence of filters with the ability to manually adjust the dimming.

    Another important parameter is the presence of a large viewing window. Welding shields with helmet mounts do not differ much in characteristics from the previous version.

    It also has an adjustable light filter and a large viewing 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. Protection against direct radiation depends on the filter settings.

    A properly selected face shield will become a means that can preserve health and, possibly, life.

    Tips for picking up

    Facial protection products described by us are available in a very large assortment on the market today. The choice to make is sometimes difficult.

    The previous part of our article describes the characteristics of each type of glasses. And it’s worth starting the choice with design features and your own professional affiliation.

    Naturally, welders will choose for themselves suitable models equipped with high-quality filters.

    In addition to the technical characteristics unique to each product, it is necessary to take into account your own comfort and individual safety. Therefore, the parameters presented below will have no less value:

    • The presence of a headband adjustment system;
    • Good indicators of resistance to shock and mechanical stress;
    • Protective screen material;
    • Product weight;
    • The presence of additional accessories.

    As for the screen material, it is advisable to choose models of shields with a maximum protection range. That is, protection should not be easy from fragments, but also from various aggressive fluids, and from a rise in temperature, albeit short-term.

    Storage and operation

    Each 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 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 buying. In the absence of such an opportunity, 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 bring significant discomfort to the eye. 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.
