Attendees will learn that a successful FR/AR clothing program is not fully defined if it does not place restrictions or set guidelines on clothing to be worn under the FR/AR uniform. Under the worst circumstances, lack of guidance on baselayer clothing could leave an employee at risk for burns.

The seminar will cover the general principles of layering FR/AR clothing. The standards require that the outermost layer be FR/AR and that inner layers not contain meltable fibers. This means never allowing non-FR/AR outerwear to be worn over an FR/AR clothing and always providing guidance on the appropriate fiber content of undergarments.

With Incident energies ranging from 4 to 30+ cal/cm2, we believe complying with the above paragraph will require multi-layer systems shirts over base layers, coveralls over shirts etc. It is important to remember that adding the ATPV’s of two garments together to estimate, predict, and/or guess the overall ATPV for a multilayer system is not allowed. The end-user has to get the fabrics tested together to document the ATPV of that multilayer system.

Attendees will take away:
  • Understanding of layering principles
  • The Pro’s and Con’s of layering
  • Understand how layering systems are calculated
  • Understanding what the standards say regarding “layered systems”
  • What resources are available regarding layering for arc flash protection
