Emergency eyewash is a sterile, isotonic, buffered solution with a pH close to that of human tears. Can be used for immediate eye or body flushing in the event of an accident involving acids, caustics, or other water soluble irritants. In the rare situation that a chemical comes in contact with eyes or skin, an eyewash station is necessary to flush out the contaminants with a saline solution. Discount Safety Gear carries permanent and portable eyewash stations and solution by North and Fend-All. The eyewash solution is a sterile, buffered liquid with a pH close to that of human tears. When the body or eyes come in contact with acids, caustics, and water soluble irritants, ordinary water will not wash out the contaminant. Instead, Fend-All™ Eyesaline Aerated water, if sprayed for fifteen minutes, can flow freely over the affected area to flush out harmful solutions.
