Can we use the new True Color Grey (TCG) shield in our old Oberon arc flash suit hoods?
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.
