Select the Apparel
Each type of fabric has inherent characteristics involving comfort, wear life, cost, appearance, and arc rating (which increases with heavier fabric weights). Arc rating is also increased when garments are layered (e.g., coveralls over a shirt and pant).

Workrite garments are ideal for meeting single and multi-layer options allowed for all risk categories. We also offer apparel expressly made for NFPA 70E compliance for tasks requiring the higher levels of protection. These specialized overalls, coats, leggings and hoods minimize the number of garments needed for HRC 3 and 4 tasks.

Each HRC specifies a different arc rating minimum. Many companies simplify their needs by choosing two sets of clothing for their people to handle all electrical tasks. One garment set with an arc rating of at least 8, for the more routine tasks of HRCs 0,1 and 2 that they wear daily. Another garment set with an arc rating of at least 40, for the more special tasks for HRCs 3 and 4. Generally, these are high-calorie flash suits, face shields and hoods that can be shared between employees when they are performing the higher level tasks.

Each of our garments is labeled with an external arc rating which falls within one of the four HRCs. So you’ll know which garments you can wear for a given electrical task.

Layering of Garments
Workers may require multiple garments to maintain safety while performing multiple tasks within a day's work. There may be many pieces of clothing, but only one philosophy: adequate protection at all times for changing risk. Layering is the sensible answer that combines comfort, convenience and safety.

The protection level provided through layering is not simply a matter of adding up each garment's ATPV. Air, in ever-present layers amid multiple garments and as the ultimate buffer between garments and skin, adds positively to the safety equation. Loose fit, not snug fit, is the goal as it creates a vital air "envelope" for additional insulation.

The layering of FR garments is an alternative to using specialized garments when developing clothing systems to meet higher ATPV levels, for example for HRC 3 and 4. Picking the right FR uniform combination can help you achieve the required protection level.

FR and natural fiber undergarments shall be permitted to be used as a layered system in order to meet the required HRC level for a specific task. A typical layering system may include a 100% cotton undershirt, a FR shirt and FR pant and FR coverall. Combined, this system can be mixed and matched in order to take you to the appropriate ATPV rating. In addition to garments, other PPE may be required to meet the hazard risk category like head, eye and hand protection.

It is important to note that any garment worn as an outer layer over FR clothing, such as jackets or rainwear, needs to be made of flame-resistant material.
