What Is the Correct Way to Use Protective Glasses?
The main function of protective glasses is to ensure that operators are prevented from or reduced eye injuries caused by accidents during the production process.
So, what is the correct way to wear protective glasses?
(1) Choose and wear glasses of appropriate size to prevent falling off and shaking during operation, which will affect the effect of use.
(2) The frame of the glasses should match the face to avoid light leakage from the side. If necessary, use glasses with eye protection or side-light protection.
(3) Prevent the mask and glasses from being damp and compressed to avoid deformation, damage or light leakage. The welding mask should be insulated to prevent electric shock.
(4) When working with face-shield goggles, replace the protective sheet at least once for a total of 8 hours. When the filter of the protective glasses is damaged by splashes, it must be replaced in time.
(5) When the protective film and the filter are used in combination, the refractive power of the lens must be the same.
(6) For air-supply welding masks with dust and gas masks, they should be maintained and used in strict accordance with relevant regulations.
(7) When the lens of the mask is covered by the humid smoke of the working environment and the moisture exhaled by the operator, causing water mist to appear, which affects the operation, the following measures can be taken to solve the problem:
① Water film diffusion method. Apply fatty acid or silica gel anti-fogging agent on the lens to spread water mist evenly.
② Water absorption elimination method. Surfactant (PC resin series) is dip-coated on the lens to absorb the attached water mist.
③Vacuum method. For some masks with a double-glazed window structure, a vacuum can be taken between the double-glazed windows.
