08/06/12Design Standards#Ezzeldin Benghuzzi, P.E.In this session we will discuss the updates to the Maintenance of traffic 2012/2013 and the 2013 Design Standards. As we know by know that the 2013 standard index was published in July 1st , 2012 and will be effective January 1st , 2013.3Effective July 1st ,2012High-Visibility Safety Apparel4Shall meet ANSI/ISEA 2010 and 2004 No changes to the Performance Class scheme Requirements for rainwear background fabric Changes related to design features Optional criteria for Flame Resistant items Guidance on service life of apparel08/06/12Design Standards#Ezzeldin Benghuzzi, P.E.The safety vests updated to ANSI/ISEA 2010 requirements, 2004 garments that are serviceable are still ok. When we order new garments require 2010 label.
