UL-Certified, Arc Flash Rated FR Insulated Bib Overalls With 14-Oz Modacrylic Lining For Cold-Weather Electrical, Pipeline, And Utility Work

The Atlas 2192 Guardian is an FR insulated bib overall rated HRC 4 with an ATPV of 41 cal. The 8 oz 88% cotton/12% nylon shell and 14 oz FR modacrylic lining provide arc flash protection and cold-weather warmth for electrical workers, pipeline crews, and utility field teams operating in winter conditions across Canada and the northern U.S.

Key Features of Atlas 2192 Guardian FR Insulated Bib Overalls

• The 8 oz 88% cotton/12% nylon shell provides lifetime flame resistance without requiring chemical retreatment, maintaining arc flash protection through repeated industrial laundering.

• 14 oz FR modacrylic lining retains warmth in sub-zero conditions while meeting flame-resistant requirements. No separate FR base layer needed under these Atlas 2192 FR insulated bib overalls.

• Arc flash rated at ATPV 41 cal with HRC 4 (CAT 4) classification, meeting the protection level required for high-energy electrical switching and transformer maintenance.

• Atlas Ultravis 2” reflective striping withstands industrial wash cycles without delaminating, keeping crews visible during nightshift pipeline, roadwork, and yard operations.

• Heavy-duty leg zippers allow workers to put on or remove the bibs over work boots without undoing suspenders, practical for layering in the field.

• Available in XS through 7XL in Royal Blue, Grey, Red, Navy, Orange, and Black. Orange meets CSA Z96-22 Class 2 Level 2 hi-vis requirements.

• UL certified to NFPA 2112 and tested to NFPA 70E, ASTM F1506, CAN/CGSB 155.20, CSA Z462, and EN ISO 11611 Class 1.

Atlas 2192 FR Insulated Bib Overalls Specifications

Applications

• High-energy electrical switching and transformer maintenance (HRC 4 environments)

• Pipeline valve operations and compressor station work in winter conditions

• Utility line crew operations during cold-weather shutdowns and tie-ins

• Oil and gas facility turnarounds requiring arc flash protection in sub-zero temperatures

• Municipal power distribution, maintenance, and substation inspections

• Petrochemical plant operations with combined flash fire and cold exposure risk

Why Choose the Atlas 2192 Guardian FR Insulated Bib Overalls

The Atlas 2192 combines HRC 4 arc flash protection with 14 oz modacrylic insulation in a single garment, eliminating the need to layer non-FR insulation under an FR shell. For warm-weather or lower-exposure environments, the Atlas 3072 Guardian FR bib overalls (HRC 2, unlined) are the lighter alternative. Pair the 2192 with the Atlas 2191 Guardian FR insulated parka for a matched HRC 4 full-body system.

Frequently Asked Questions

What HRC rating do the Atlas 2192 FR bibs carry?

HRC 4 (CAT 4) with an ATPV of 41 cal/cm². This is the highest arc flash protection category under NFPA 70E, required for tasks like high-energy switching, transformer racking, and live bus work.

Can I machine wash these FR insulated bib overalls?

Yes. The flame resistance is built into the fiber, not applied as a chemical treatment, so it lasts the life of the garment through repeated industrial laundering. Follow the care label for wash temperature. The Atlas Ultravis reflective striping is also rated for industrial wash cycles.

What sizes are available for the Atlas 2192?

XS through 7XL. All sizes are regularly stocked at Cleanflow. If you need a specific size confirmed before ordering, contact us at 1-866-335-1078.

Does the orange model meet CSA Z96 hi-vis requirements?

Yes. The orange (2192OR) meets CSA Z96-22 Class 2 Level 2 high-visibility standards. All other colors (Royal Blue, Grey, Red, Navy, Black) meet Class 1 Level FR, which provides reflective visibility but not the fluorescent background required for Class 2.

What is the difference between the Atlas 2192 and the Atlas 3072?

The 2192 is insulated (14 oz modacrylic lining) and rated HRC 4 (ATPV 41 cal). The Atlas 3072 is unlined and rated HRC 2 (ATPV 11 cal). Choose the Atlas 2192 for cold-weather work requiring higher arc flash protection. Choose the 3072 for warm-weather or indoor environments with lower arc flash exposure.

Can I wear these bibs over other FR layers?

Yes. The heavy-duty leg zippers let you pull the bibs on over boots and additional FR base layers. The sizing runs standard; if you plan to layer an FR parka underneath, consider ordering one size up. Pair with the Atlas 2191 Guardian FR insulated parka for a matched HRC 4 system.

Does Cleanflow ship FR bibs to the USA?

Yes. Cleanflow ships across Canada and the USA. Orders to the U.S. require additional transit time to reach the international shipping warehouse before dispatch. You will receive tracking details once the order ships. Free shipping applies to qualifying orders.

How do I know when to replace FR bib overalls?

Replace when the shell fabric shows holes, tears, thinning, or permanent contamination with flammable substances. The flame resistance itself does not wash out or expire, but physical damage to the fabric compromises protection. Inspect seams, reflective tape adhesion, and zipper function at the start of each shift.
