Eye protection --- EH & S 1 Four steps for eye and face protection 1. Identify the elements that are harmful to the eyes in the workplace 2. Understand the risks of the elements to the eyes 3. Select the eye and face protection products accurately 4. Use the eyes accurately Face protection. 2 Heat includes thermal radiation, hot metal splashes, and hot sparks. Secondary occurrences occur in homework such as furnaces, molten metal pouring, and mechanical grinding. 3 Impacts occur mainly in grinding, grinding, scraping, cutting, shaving, shoveling, chiseling, planing, purging, nailing and machining processes. The impact energy of the impacts generated by mechanical work is higher than that of manual work. 4 Chemicals occur in the homework of chemicals such as electroplating and painting. Risks include chemical splashes, vapors, and irritation. 5 Dust Dust refers to solid particles suspended in the air. It occurs during the destruction of solid materials. 6 Light radiation includes glare and harmless light of various intensities. Secondary work is in various homework such as outdoor homework, welding of various types, and disposal of molten metal. 7 Eye and Face Protection in Four Steps 1. Identify the elements that pose risks to the eyes in the workplace 2. Understand the risks that the risk elements pose to the eyes 3. Select the eye and face protective equipment accurately 4. Use the eye and face protective equipment accurately. 8 understand our eyes 1. cornea 2. aqueous humor 3. lens 4. vitreous body 9 For example: arc light-arc eye?? When the cornea is inflamed, pain and grief and other sensory symptoms occur within hours, and last for several days How does sand get into the eyes? 10 Example: Solid splashes cause secondary glaucoma, cataracts, fear of light, tears, frustration, and rainbow-like appearance around the lights at night. A sharp object penetrates into the eye unexpectedly or a small fragment pops into the eye at a high speed. The chemical splatter through the eyeballs causes eye burns, pain, sorrow, photophobia, tears, inability to close eyes, and decreased vision. The sinker's eyelids are swollen and swollen, the conjunctiva is pale and even bad, the cornea is grayish white, and the pupils are narrowed. Chemical irritation The vapors of chemicals that are irritating to the eyes can make people feel pain, grief, and tears, such as formaldehyde. Toxic chemicals can cause blindness, such as methanol. 11 Four Steps of Eye and Face Protection 1. Identify the elements that pose risks to the eyes in the workplace 2. Understand the risks to the eyes from the elements of the risk 3. Select the eye and face protective equipment accurately 4.
