HAZARD SPECIFIC FACESHIELD WINDOWS EXTEND FACESHIELDS APPLICATION

Faceshields are the most under utilized major PPE group. It has been determined that the "utilization rate" (the number of workers wearing faceshields measured against the number who should be wearing faceshields according to OSHA) is less than 20%. Faceshields often get lost in the confusion about "primary" eye protection and "secondary" eye protection when PPE buying decision makers think that providing protective spectacles (primary eye protection) is all they have to or should do.

This blog has three earlier posts (May 29, 2011, March 28, 2010, and January 14, 2010) on faceshields but none of them focuses on the extensive number of hazard specific special windows that allow faceshields to be used in more and different applications. Most PPE buying decision makers are aware of clear windows that erect a protective barrier between the wearer and the hazards of the job. But they may not be as familiar with the array of hazard specific windows they could be using.

The special windows we will discuss are produced by the Fibre-Metal by Honeywell brand. To the best of our knowledge and experience, they provide the widest, deepest and highest quality selection of faceshield windows on the market today. As always, if there are other brands who meet the same standards, by all means include them in your decision choice set.

Specialty faceshield windows begin with tinted models. These models protect from glare both indoors and out. They come in green and gray in unique "wraparound" and "extended view" sizes that cover more exposed face area than ordinary sizes. The Fibre-Metal brand windows are .060" think (most brands are only .040" thick) for an extra margin of protection, yet they weigh no more than the lesser brands. WARNING: Tinted windows cannot be used for electric arc, OxyFuel welding or cutting and Plasma Arc cutting.



True-View gray windows protect from glare while allowing the wearer to see in natural color. That is vital to outdoor workers who must be able to see warning lights and signals and who may have to work with color coded wires or other materials.  WARNING: True-View gray windows cannot be used for electric arc, OxyFuel welding or cutting and Plasma Arc cutting.





IR/UV windows have become the preferred method of face and eye protection for Oxy-fuel welding and cutting and plasma arc cutting. The Fibre-Metal brand windows are molded from the best all around window base material and utilize the highest quality IR/UV absorber to produce consistent shade 3, 5 or 8 protection throughout the window with excellent optical qualities. Lesser brands use dyes that can fade and scratch off over time. WARNING: IR/UV windows cannot be used for electric arc welding. Shade 3 IR/UV windows are often used by welders helpers who work in proximity to electric arc welding but cannot be used to do electric arc welding.




Gold plated windows are used in high heat applications.   Gold coating deflects heat, keeps it from over heating the inside of the window. Blocking heat reduces the internal faceshield temperature by 50 degrees F or more.  Gold coating also helps maintain the dimensional stability of the window by keeping it from softening or becoming distorted. Unique gray base material reduces the glare common in lesser brands. Proprietary coating method produces a hard surface to reduce scratching or peeling. The widest selection of sizes and models in the industry.



Wire mesh screens provide a different kind or protection from high radiant or blasts of heat. They dissipate and absorb the heat while allowing air circulation and an unobstructed field of vision. Used primarily in steel mills and blast furnaces. The Fibre-Metal brand by Honeywell has a size and style for most applications. WARNING: Not a high impact protector. Should not be used where the risk of hazardous splash exsists.




There is really no reason why faceshields should not be used. Research has shown that eye and face injuries can be reduced significantly when faceshields are used in conjunction with protective spectacles. As the faceshield related posts in this blog have shown, there are vast differences in faceshield design, material, workmanship and quality. Our goal is not to endorse a brand, it is to make our readers aware of what is available so that they can make a more informed choice for their workers. Being aware of the availability of hazard specific speciality windows should help in utilizing more faceshields in your operation.


The selection of a specific faceshield should only be done by on site, qualified, responsible safety officials after a thorough hazard analysis. Read carefully and note all product information and markings information concerning ANSI Standards compliance including any special designations such as "High Impact Protector", ANSI Z87.1 +, etc. Always wear protective spectacles under faceshields. Failure to do so could result in serious injury.
