The Occupational Safety and Health Administration (OSHA) regulation 1910.133 contains a guide for choosing the appropriate filter lenses, based on various operations (see Figure 1at the bottom of page). The type of welding application determines the correct shade for eye protection. Welders are protected from this light by wearing a very dark filter that allows them to look safely at the welding arc, enabling them to produce a quality welded seam. The light given off during most welding processes is as bright as the sun, which makes retinal damage a real issue for welders, according to Barker. An unprotected worker could be standing off to the side while others are welding and a few hours later end up with painful eyes," Barker said. "It doesn't take much exposure to be affected by UV rays. Side shields also are important if indirect exposure is a possibility. Felix Barker, director of research at the Pennsylvania College of Optometry, this blocking ability makes clear safety glasses helpful for guarding nonwelders from indirect exposure to UV rays generated by welding. Goggles, too, come in different styles for protection from splashes (goggles without vents or with indirect vents) and protection from particles (goggles that feature side vents for airflow).Ĭlear polycarbonate safety glasses, in addition to guarding against particles or splashes, also can block UV radiation up to 385 nanometers. For other jobs, goggles might be more practical because they provide a seal around the eyes. For some applications, safety glasses with side shields are necessary to protect against flying particles. Many styles of clear safety glasses are on the market, offering everything from side shields to wraparound lenses to brow guards.Ĭhoosing the right style comes down to the hazards of the working environment. Clear Lenses for Impact ProtectionĬlear polycarbonate lenses meet the American National Standards Institute (ANSI) Z87.1-1989 standard for industrial impact resistance and work best for indoor applications for which protection from splashes, sparks, or flying particles is necessary. While the type of protection you choose ultimately depends on your employees' work applications, the following is a general guide to the types of lenses and equipment available to protect welders from exposure to optical radiation. While pupillary reflex and shading of the eyes are natural reflexes to guard the eye from exposure, eye protection is still necessary to protect those who may accidentally be exposed to a welding arc. Workers are at risk of welder's flash injury even when they are not involved directly in the welding process. IR light is fundamentally less damaging, but workers in blast furnace environments should be protected against exposure, which has been associated with chronic damage to the human lens. Exposure to UV light can lead to photokeratitis, a painful experience more commonly known as snow blindness or welder's flash. Sometimes damage occurs without the worker realizing it, because UV and IR radiation cannot be seen. 1Įxposure to UV and IR rays can damage the eyes and the skin. Arc welding and cutting, as well as laser welding, cutting, and brazing, can expose workers to this type of radiation. Radiant energy exposure, also called optical radiation, occurs with work applications that involve intense concentrations of ultraviolet (UV), infrared (IR), and intense visible light. 1.The Dangers of Ultraviolet and Infrared Light Ready to beat that sweltering summer heat? Check out these DIY backyard sun shade ideas that will have you spending your entire summer outdoors. Keep in mind that adjustable panels are the most useful you can always remove or retract them if you decide you need more light, or if heavy wind threatens to damage them. Use shade panels to define outdoor seating areas, or add privacy from nosy neighbors around your pool or deck. These nifty projects do more than just keep off the sun.
