When performing work with the operation of power tools with a high level of danger, it is necessary not only to observe all safety measures, but also to use protective ammunition. To prevent accidental contact with sparks or the finest dust, you must use safety glasses for the grinder.
Materials used for manufacturing
All existing glasses consist of a mount and a protective part. In some models, additional elements may be provided to adjust the length of the mount and to provide ventilation. For greater convenience, manufacturers often equip goggles with rubber or fabric linings, as well as plastic or metal fasteners.
For the production of safety glasses, rubber or silicone, plastic, polymer compounds and glass are often used. So, flexible rubber or silicone models are characterized by great convenience. The plastic used for the manufacture of fasteners and moving parts guarantees the comparative strength of the product and reliably protects the eyes from possible splinters, shavings and other large particles. Durable polycarbonate glasses can easily withstand the effects of some caustic chemicals, high temperatures and mechanical stress. An additional protective layer and various filters are sometimes applied to the surface of shockproof glass lenses.
Some manufacturers manufacture glasses based on minerals, organic and inorganic materials. As a rule, polymer compounds are used for this, mixed with components that enhance protection against ultraviolet radiation and too bright lighting.
Ventilated and non-ventilated models
In the process of using goggles, many workers had to deal with fogging of the lenses. To get rid of this problem, you need to purchase ventilated models. Today, manufacturers produce glasses with side or direct ventilation. In the first case, the ventilation holes are located in the side of the glasses, in the second - they are evenly distributed throughout the body of the product.
Non-ventilated structures secured with the help of arches can significantly complicate the work. The arbitrary ventilation of such glasses occurs due to a loose fit to the face of the employee.
What to look for when buying?
One of the main criteria that should be followed when choosing is considered the desired level of vision protection. At the same time, it is necessary to take into account the complexity, duration and regularity of carpentry and metalwork using a traumatic tool. One of the most successful options will be goggles closed.
Choosing personal protective equipment, you need to be guided not only by functionality, but also by the degree of comfort. Before purchasing, be sure to try on the selected model and make sure that the product will not slip when the head is tilted. In addition, it should not obstruct the view or distract from the work performed.
Varieties of products and their characteristics
Depending on the degree of openness, all products can be divided into:
- Protective goggles, closed type, preventing the entry of chemical vapors, dust, small and large particles. They are fixed to the head with a stretch rubber band or a special strap. For maximum protection of the worker’s eyes and face, models have been developed that are a cross between glasses and a mask.
- Protective goggles of the open type, in appearance resembling standard sunscreen products. Some models have lateral corner protection. Such glasses protect the eyes from the ingress of small particles popping up from under a working grinder, but they do not save from harmful fumes, smoke and dust.
Polycarbonate, plastic, or mineral glass are often used to make lenses . Transparent goggles are considered the best option. Mineral glass lenses are scratch resistant and are characterized by increased reliability and a long service life. The only drawback of such products is their inability to withstand strong shocks.
Care and storage conditions
Sooner or later, any products become worthless. In order for protective goggles to last as long as possible, you must follow the basic rules for care and storage. Before each subsequent use, it is recommended that you carefully inspect the product for cracks, abrasions, and other visible defects.
To remove dust and dirt, wipe the lens with a soft, damp cloth. In many construction stores, you can purchase special material, impregnated with a special composition designed to disinfect such products. Protective goggles should be stored in a special case that reliably protects them from possible damage.
