The life cycle of protective glasses

For the safe production of enterprises, employers must promptly replace expired products, especially special labor protection products, in accordance with national requirements and product use periods. To avoid accidents involving employees using expired personal protective equipment, companies must first recognize the importance of personal protective equipment for safe production. So, what is the life cycle of protective glasses? The life cycle of protective glasses depends on the environment and type of use. The standard for ordinary splash protection is 24 months. If it is used frequently, it will be 3 months. However, it is required that the lens must not show serious scratches, and if scratches or damage occur, they should be replaced in time. Selection of safety glasses: There are many types of safety glasses, including dust-proof glasses, impact-proof glasses, chemical-resistant glasses, and anti-light radiation glasses. The first three glasses look like the lenses are colorless glass, but in fact, due to the different protective effects, the characteristics of the lenses are obviously different. Some workers engaged in industrial production need to wear glasses for operation. These glasses are not for decoration and fashion, but for protecting eyes from harmful factors. Therefore, such glasses are called safety glasses. Workers engaged in electric welding, gas welding, steel making, and glass blowing should wear anti-arc radiation glasses. However, the lenses of arc-proof radiation glasses have dark and light colors, which are designed according to different requirements. The selection should be based on the strength of the arc during operation. The intensity of the arc and the color should be deep; otherwise, light-colored lenses should be selected. If the arc light is strongly worn with light-colored goggles, some infrared rays will stimulate and damage the eyes through the lens, and occupational cataracts will occur in the long term; otherwise, the arc light is weak and wearing dark safety glasses for a long time will greatly reduce vision. Therefore, every worker who needs to wear protective glasses should understand the harmful factors of his working environment, wear appropriate safety protective glasses, and should not wear a pass. Dustproof glasses are used in environments with a lot of dust, and the general lens fastness requirements are not high. No matter the eye mask type or the flat mirror type, they are made of general flat glass lenses. The anti-impact glasses are used to prevent the small particles from flying out from piercing the eyes. The lenses require impact resistance. For example, the lathes, sanders and stone workers should wear anti-impact glasses. The iron sand and crushed stone are smashed when they strike the glasses, and the eyes will be more damaged. The lenses of chemical-resistant glasses are resistant to acids and alkalis and corrode, which is not available in other glasses.
