Frequently Asked Questions


The NFPA 70E Standard requires that all arc flash PPE is pre-use inspected. Refer to Oberon’s resource section of the website for literature resources including User Guides and Storage, Use, Care & Maintenance files. While inspecting your arc flash faceshield if you identify a problem do not use the product until the issue has been repaired, cleaned or replaced. When pre-use inspecting your Oberon arc flash suit you should inspect each item one at a time.

 

The following steps apply when pre-use inspecting your Oberon arc flash faceshield;

  • Check the faceshield visibility, inspect for excessive scratching. If visibility is impaired or the shield is cracked or damaged remove from use (replace with appropriate lens).
  • Manually adjust the shield mounting mechanism (adapters) to ensure wing nuts are firmly in place, do not over tighten or the shield won’t be able to operate correctly.
  • Inspect adapters for cracks or damage, ensure fingers are locked into hard hat slots.
  • Check hard hat slots and inspect for cracks that could allow the adapter to slip out.
  • Ensure the nuts and bolts fastening a lower chin guard (double crown) are tight before use.

Refer to Oberon’s Sizing Guide section of the website. Alternatively, an Oberon Representative can help arrange for an arc flash suit sizing kit to be provided for your workers to use. The proper garment size will ensure electrical workers are protected, comfortable and productive. Arc flash suit sizes should be selected to be loose fitting over top of the worker’s uniform or everyday clothing. When sharing arc flash suits be certain to ensure every possible electrical worker has a comfortable size available to wear.

 

Oberon arc flash suits are sold in alpha sizes from Small up to 5XL. All Oberon garments are available in regular (Standard height), tall, extra tall or short vertical measurements. The arc flash suit size must be adequate to completely cover the workers body, not showing the underlayers in any area.

Oberon promotes the use of LED headlamps on all arc flash faceshields and suit hoods to enhance the workers ability to properly see the work task. Oberon has performed limited testing of the products we support. The arc flash exposures were relevant to the protection provided by the arc flash PPE. During testing none of the LED lamps exploded and we observed no signs of concern regarding melting, dripping or continued ignition/after flame.

No, Oberon has been a strong advocate against the use of this type of arc flash suit for the past 20 years. Long Coat with leggings style arc flash suits are a protection concern for workers! If a worker doesn’t kneel or squat with their legs together a large opening is created at the bottom. Furthermore, thermal incident energy can deflect and chimney up inside the long coat. Arc flash suits should be a Hood with either a Coat & Bib-Overall or Coverall. If you have a long coat style arc flash suit it should be replaced.

Oberon arc flash faceshields and suit hood shield windows are available with anti-fog coatings. Before each and every use the anti-fog coating must be activated. Workers must use humidity to activate the anti-fog properties by pulling the inside of the faceshield or hood lens towards them and breathe on the surface. It’s important for your shield lens to be at room temperature for best results.

 

When using an Oberon arc flash suit hood, consider using a hood ventilation system that circulates air to your breathing zone. Oberon’s system delivers the external air directly down the inside of the hood shield window to reduce fogging in extreme conditions.

No, older Oberon hoods that have a green/yellow shield window lens cannot be exchanged for the new clear TCG shield window. When Oberon designed the hoods for the new TCG shield lens, changes were made to the fabric construction and installation method. The new TCG shield lenses have metal snaps that make assembly and disassembly easier for the worker. All older Oberon hoods must be replaced with complete TCG hoods when upgrading to the new technology.

 

The ASTM F2178 Standard requires the hood to be tested as you would use it. This final product testing requirement is critical for the product to perform as needed during an arc flash exposure.

Yes, Oberon has different adapters available that can fit other manufacturer’s hard hats. However the selection is limited and you must consult with an Oberon Representative for assistance. The originally supplied Oberon hard hat shall never be switched for another manufacturer’s hard hat without first changing the adapters. Failure to comply will result in broken adapters and increased risk to the worker. Oberon has conducted all of its arc flash testing using Oberon manufactured hard hats. For the best results you should always use an Oberon hard hat.

This is highly unlikely. Workers need the fresh air provided by an Oberon hood ventilation system to properly function during a work task execution. The risk of heat stress causing disorientation and dizziness is far more severe than the likelihood of the fan unit pulling in toxic fumes from an arc flash. Oberon has tested its hood ventilation system and made no observations of the fan causing any increased harm to the worker. When the fan unit is directly exposed to an arc flash incident the motor was rendered inoperable.

Both Oberon green/yellow and new clear True Color Grey (TCG) lenses provide protection from an arc flash incident. A clear grey lens is safer than the old green technology because the likelihood of a worker making a mistake that could cause an arc flash has been reduced.

 

Oberon’s True Colour Grey is a medium density filter that allows all visible light to pass through it with no distortion. Oberon TCG is a nearly clear lens that provides the same protection as old style green with the difference being workers can finally see the true colours of their work.
