===Arc flash=== *Also known as "arc eyes", "flash burn", "snow blindness", "ultraviolet keratitis", or "corneal flash burn". It's analogous to a sunburn on your eyeballs. *Avoid "blind" tack-welding, i.e. closing your eyes, blocking your eyes, or looking away when you tack. *Take steps to ensure that nobody "walks in" on a welding job without eye protection, or they could get arc flash (i.e.: sign on the door). *Don't weld with a white shirt on- white can be too reflective. *Don't weld with "cool" sunglasses as protection. Being blind isn't cool. ====Symptoms of eye injury from welding flash==== *Feels like you have sandpaper rubbing your eyeballs *Bloodshot eyes *Light sensitivity *Excessive tearing *Moderate to severe pain *Can't close eyes (can't sleep) ====What about using potatoes or potato juice?==== Ignore the old welder's tale of using a potato or potato juice. It's not sterile and could cause an infection. Instead, use eyewash from a first aid kit. See a doctor. ====What about using over-the-counter eyedrops?==== Don't use topical anesthetic drops, because they can slow the healing of the cornea. However (ask your doctor), you may be advised to use over-the-counter '''lubricant''' eyedrops. ====When to see a doctor about arc flash==== If you have worsening pain in your eyes, or your vision blurs or changes, you should see a doctor, preferably an ophthalmologist. Or, just go to an emergency room. The doctor will examine your eye, typically with a [http://en.wikipedia.org/wiki/Slit_lamp slit lamp]. You may receive some eyedrops to numb, dilate, or dye your eye to aid in the examination. Then, you'll probably get some eyedrops to take home, to help alleviate the pain or lubricate your eyes. In most cases, you should be recovered within a few days. ====Articles and tech info==== *[http://www.eyesafety.4ursafety.com/terms.html Safety glasses terms, types, and lens tint descriptions, from 4UrSafety.com] *[http://www.emedicinehealth.com/corneal_flash_burns/article_em.htm Corneal flash burn, from eMedecineHealth.com] *[http://www.equipdirect.com/index.asp?PageAction=Custom&ID=3 Safety glasses glossary, from EquipDirect.com] ====OSHA standards==== *[http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=9778 OSHA standard for eye and face protection] *[http://www.labtrain.noaa.gov/osha600/refer/menu11a.pdf OSHA guide listing proper filter lens shade number for different welding operations] ====Discussions==== *[http://www.hotrodders.com/forum/safety-glasses-slag-135401.html Safety glasses and slag] *[http://www.hotrodders.com/forum/burned-eyes-121146.html Burned eyes] *[https://www.aws.org/cgi-bin/mwf/topic_show.pl?pid=47289 Home remedies for flash burn]
