WHAT IS DIFFERENCE BETWEEN ANSI/ISEA 107-1999 AND ANSI/ISEA 107-2010?
The revision in 2010 was primarily a clarification of intent on the part of ANSI. The three garment classes were to be based upon the wearer's activities and determined by the total square inches of florescent background materials and the reflective materials. The addition of headwear to the list of items covered and the inclusion of logos were reviewed. Distinctions between woven and knitted background materials rounded out the revision.
CLASS I Apparel for use in activities that permit the wearer's full and undivided attention to approaching traffic. There is ample separation of workers from traffic. Example - parking lot attendants
CLASS II Apparel for use in activities where greater visibility is necessary during inclement weather or in work environments higher risks. Workers who perform tasks that divert their attention from approaching traffic or those with proximity to passing vehicles require a minimum of Class II. Example: Railway worker.
CLASS III Apparel for the highest level of visibility for workers facing serious hazards and or high task loads that require attention away from their work. Garments cover more of the body, such as arms and legs to differentiate the worker from inanimate objects such as cones. Example: highway construction or flagger.
