Wearing eye protection is required by Occupational Safety & Health Assosiation regulation whenever and wherever potential eye hazards exist. Hazards requiring eye or face protection include flying particles; molten metal; liquids including acids or dangerous materials, biological or radioactive materials; chemical gases or vapors; and harzardous light radiation. These and other eye hazards may exist in labs, shops, mechanical rooms, construction sites, hazardous material storage areas, emergency zones, and other locations. Departments, labs and centers are responsible for providing appropriate protection to anyone who works in, studies in or visits an area where there are hazards to the eyes and/or face.

Wear eye protection in areas where potential eye hazards exist whether you are working, observing or visiting. In some circumstances safety glasses or goggles alone may not provide adequate protection; a face shield may also be necessary. Eye and/or face hazards could be released when something explodes, spills, breaks, falls or splashes; by operations that produce chips, dust and other flying particles; and by operations which produce non-ionizing radiation such as welding or lasers.

Only wear eye protection that meets the SABS standard for impact resistance. Don't rely on normal prescription glasses or "visitor" safety glasses that do not have the SABS marking, because these does not meet the standard for impact resistance.

safety glasses: with side shields (built in or clip on)
goggles for chemical splash, mist: indirect vents
goggles for chips, dust: direct vents
faceshield: must be worn with goggles to prevent liquid chemicals from getting into the eyes. Must be worn with safety glasses to prevent chips or other particles from getting into the eyes.
