Understanding the do’s and don'ts of layering FR apparel is not always as straightforward as it may seem. We’ve taken the time below to outline some of the common facts and myths when it comes to layering flame resistant and arc rated clothing.
Don’t Assume When It Comes to Evaluating Your Arc Flash Rating
Safety on the job starts with understanding how to evaluate your garments arc rating appropriately. Determining the correct protection level is not as simple as adding A + B together.
In most instances, the arc ratings will not be the same as a simple A + B calculation. The change in APTV value results from the air space created between two layered garments, which acts as another insulator and layer of protection.

Don’t Choose Cotton or Synthetic Materials for Your Base Layer
Instead of choosing your favorite cotton or performance tech t-shirt, opt for an FR moisture wicking garment. Why? An FR garment with permanent moisture wicking technology will pull moisture away from your skin to keep you feeling cool and provide the FR/AR protection you need.
Don’t Think All FR Clothing Offers Permanent Moisture Wicking Capabilities
Not all FR clothes are created equal. Some garments offer moisture wicking “finishes” that will wash out or wear off over time. When possible, always select FR clothes with permanent moisture wicking technology to help you stay cool, no matter how many layers you are required to wear. Look at the tag to help you determine if your garment has permanent moisture wicking capabilities. It should have a blend of hydrophobic and hydrophilic fibers to wick moisture away from your skin effectively.
Do Select a Layering System with Permanent Moisture Wicking Technology
Moisture wicking garments are designed to pull moisture away from your skin, helping you feel cool and dry, quickly. As you add layers, make sure each additional garment adds moisture wicking capabilities so sweat will be pulled away from your skin through the fabrics, layer by layer, to dissipate on the outer surface.
Our video below will help you select the right layering system components and appropriate APTV-rated combinations. Read our How an FR/AR Layering System Manages Moisture blog to get more in-depth information on each moisture-wicking layer.
Do Think About the Versatility of Dual-Hazard Garments
By encouraging your team to wear an FR layering system from base-layer to outer layer, you can help ensure they are protected even when they move through various duties with different risk hazards.
Don’t Assume the Weather Will Cooperate
If the weather changes unexpectedly, your team may be at risk if they need to add or remove clothing layers quickly and some of their layers are not FR garments. You can combat this risk by selecting FR clothing with moisture wicking technology -- it will offer the arc flash protection you need, should you be required to add or remove layers, and the moisture wicking capabilities you want to maintain your body temperature in variable weather.
Choosing an FR garment that lets you stay focused on the job is critical to help you manage occupational hazards. To learn more about combating heat stress by modifying your FR apparel, download our eBook: How to Combat Heat Stress with FR Apparel.
