It is understood that occupational eye injuries account for about 5% of all industrial injuries and 50% of eye hospital injuries. According to statistics published by the China Eye Injury Conference, the annual rate of eye injury among employees nationwide is 1%-3%, while in some industrial sectors, the rate is as high as 34%.
Eye injury in industry 1. Foreign body eye injury Foreign body eye injury refers to dry grinding of metal, cutting non-metal live cast iron, using hand tools or portable electric tools, or using pneumatic tools to wash and repair metal castings , When cutting rivets or screws, cutting or scraping boilers, crushing hands or concrete, etc., sand, metal debris and foreign objects enter the eyes or impact the face. 2. Non-ionizing radiation eye damage Non-ionizing radiation eye damage, including strong visible light, ultraviolet and infrared, emits photon energy that is not enough to produce ionization in the atoms that absorb molecules, so it is called non-ionizing radiation. In industrial production, electric welding, oxygen cutting, furnace, glass processing, hot rolling and casting, etc., the heat source can produce strong light, ultraviolet and infrared. 3. Ionizing radiation eye damage, ionizing radiation eye damage, including radiation such as alpha particles, beta particles, gamma rays, X-rays, thermal neutrons, slow neutrons, fast neutrons, protons and electrons. 4. Microwave and laser eye damage These two waves are also electromagnetic non-ionizing radiation. Microwaves are widely used in radar, communications, anticipation, detection, military, industrial food processing and other sectors.
Because of these injuries, protective glasses must be worn during the production process. It is precisely because of these injuries that protective glasses are particularly important!
The role of protective glasses 1. Anti-fixing debris is mainly used to prevent mechanical damage to the eyes such as metal or sand and gravel debris. The spectacle lens and spectacle frame should be strong and shock resistant. There should be venting holes around the frame. Protective lenses can be tempered glass, glue-bonded glass or copper wire mesh protective glasses.
2. Anti-chemical liquid is mainly used to protect the eyes from chemical damage caused by irritating or corrosive solutions. Ordinary flat lenses can be used, and the frame should be covered to prevent the solution from splashing. Usually used in laboratories, hospitals and other places, general medical glasses can be used universally.
Let’s use a small video to experience what a tomato that simulates human eyes looks like after being hit by an object with and without protective glasses.
Precautions for use 1. The selected goggles should be products that have been inspected by the product inspection agency; 2. The width and size of the goggles should be suitable for the user’s face; 3. The lenses are worn and rough, and the frame is damaged, which will affect The eyesight of the operator should be changed in time; 4. The goggles should be used by special personnel to prevent the infection of eye diseases; 5. The filters and protective films of the welding goggles should be selected and replaced according to the requirements of the specified operation; 6. To prevent heavy falls and heavy pressure, Prevent hard objects from rubbing the lens and mask.
