Eye Protection, Part 2: How to Avoid Fogging

By Phil Johnson, Honeywell Safety and Productivity Solutions |

A look at the hidden dangers of lens fogging and how to prevent them Fogging is the number one problem faced by safety eyewear users in the chemical process industries (CPI; Figure 1). Across applications, both indoors and out, the environments where CPI workers conduct daily tasks are demanding. Fogging on untreated lenses is nearly impossible to avoid. Figure 1. Fogging is the main problem faced by safety eyewear users in the chemical process industries[/caption] Lens fogging might seem like no big deal. But maintaining a clear, fog-free view is vital to the wellbeing of CPI workers and employers alike. When tasks are conducted with fog-obscured vision, workers risk not only eye injury but also bodily harm. It takes seconds — or less — for a potentially catastrophic event to occur: a slip or fall; getting struck by equipment or caught in machinery; or coming into contact with harmful chemicals or electrical current. Productivity and compliance are at serious risk, too. With so much at stake, it’s easy to see why employers seek effective anti-fog solutions, and why eyewear manufacturers strive to develop longer-lasting anti-fog coatings. But not all anti-fog-coated lenses deliver the same level of protection or consistency,…
