Two apparel companies, National Safety Apparel and Carhartt, just announced voluntary product notifications on their arc rated navy blue sweatshirts made since 2014. The issue is the sheen on the fabric. Additional testing was performed and the arc rating on this garment has been changed from a 34 cal rating to a 27 cal rating. In the interest of employee safety, please read the linked notice. The hi viz sweatshirts are unaffected and are not part of this notification. Here is the link to the notices.
If this apparel was sold by G&L Clothing, expect a phone call from them to explain the situation and the options you have under the notification. Or you may contact Rex Coble at G&L at 800-222-7027 or email@example.com.
