[Q&A] What are the standards for "labor or occupational safety protection glasses"?

Q: My company has stipulated that you must wear protective glasses when you enter the studio. However, the quality of labor insurance glasses issued by the company is very poor. Many people feel dizzy after 8 hours a day. Everyone knows that the bad quality of the glasses hurts the eyes a lot. This is not protection on the surface but it is long-term damage to the eyes. Do not wear: The company has system assessment; Dai: hurt himself. Does the country have any standards for "labor or occupational safety protection glasses"?

Answer: Some workers who are engaged in industrial production need to wear glasses. These glasses are not used for decoration and fashion, but are used to protect the eyes from harmful factors. Therefore, these glasses are called safety glasses.

Workers engaged in welding, gas welding, steel making and glass blowing should wear anti-arc radiation glasses. However, the color of the lenses of the anti-arc radiation glasses is deep and shallow, which is designed according to different requirements. The choice should be properly selected according to the strength of the arc during operation. The arc light is strong and the color is dark; otherwise, light colored lenses should be selected. If the arc light wears a light-colored protective goggles, part of the infrared rays will stimulate and damage the eyes through the lens, and will suffer from occupational cataracts in the long term. On the other hand, if the arc is weak and the dark safety glasses are worn for a long time, the vision will be greatly reduced.

Therefore, every worker who needs to wear protective goggles should understand the harmful factors of his operating environment and wear appropriate safety glasses.

Dust-proof glasses are used in a dusty environment. Generally, the fastness of the lens is not high. Regardless of the eye mask type or flat mirror type, general flat glass lenses are used. The anti-impact spectacles are used to prevent small particles from flying through the eyes. The lenses require impact resistance. For example, laver, sander, and mason should wear anti-impact glasses. If these workers wear ordinary dust-proof glasses, then Iron sand and gravel are broken when they fly into the eyeglasses, and the eyes will suffer more damage. Anti-chemical glasses lens acid and alkali, and corrosion, which is not available in other glasses.
