Eyeglass frame and face should be consistent to avoid side leakage

There are various types of eye and face protection equipment available, each designed to address specific hazards. These can be categorized into nine main types based on their protective functions: dust protection, water resistance, impact resistance, heat resistance, electromagnetic radiation protection, radiation shielding, chemical splash protection, sand resistance, and glare reduction. Choosing the right type of protection is essential for ensuring safety in different work environments.

Use of Welding Glasses and Masks

According to statistics, electro-ophthalmia (a type of eye injury caused by exposure to ultraviolet light) is a common issue among workers involved in welding operations in industrial and mining enterprises. This often occurs due to improper selection or use of protective eyewear. To prevent such injuries, operators should follow these key guidelines:

1. Ensure that all glasses and masks have been tested and certified by relevant authorities before use. 2. Choose the right size and fit to prevent the equipment from slipping or shaking during work, which could compromise protection. 3. Adjust the frame so it fits snugly against the face, minimizing light leakage. Use side-shielded goggles when necessary for full coverage. 4. Avoid exposing masks and glasses to moisture or pressure, as this may cause damage or reduce effectiveness. Welding masks must also be insulated to prevent electric shocks. 5. Replace the protective lens of mask-type goggles at least every 8 hours. If the filter becomes damaged due to splatter, replace it immediately. 6. When using combined lenses, ensure that the refractive power of each lens is consistent to maintain clear vision. 7. For air-fed or gas masks, follow strict maintenance and usage procedures as outlined in the manufacturer’s guidelines. 8. If the lens becomes fogged due to moisture from the environment or the operator's breath, consider the following solutions: - Apply an anti-fog agent like fatty acid or silicone to the lens to spread out moisture evenly. - Use a surfactant-coated lens (such as PC resin) to absorb the fog. - For masks with a double-layer glass design, create a vacuum between the two layers to prevent fogging.

Use of Anti-Electromagnetic Radiation Eyewear

Electromagnetic radiation is invisible, silent, and intangible, but certain frequencies of microwaves can cause a warming sensation. The effects of exposure may take years to manifest, and by the time symptoms appear, significant harm may have already occurred. Therefore, proper protection against electromagnetic radiation is crucial.

1. Identify areas where microwave radiation exceeds safe limits and post warning signs. Workers entering these zones must wear shielding gear and anti-microwave glasses. 2. Select appropriate shielding suits and glasses based on the frequency and intensity of the radiation source at the worksite. 3. Prefer glasses with full eye protection to block microwave diffraction and reduce potential harm to the eyes. 4. Avoid contact with oils, acids, or other chemicals while using the eyewear, as they may degrade the shielding material. 5. In addition to wearing protective gear, avoid looking directly at radiating devices such as feeding horns, open waveguides, or reflectors. Keep a safe distance from the radiation source and implement shielding measures to further reduce exposure risk.
