1. Door latches on equipment can't be counted on to hold the door closed during an Arc Flash Event.
Agreed

2. Once you have done an Arc Flash study, you can still use the NFPA table to select PPE for work where all doors are securely closed and fastened. Greg stated that NFPA officials have indicated that Arc Flash calculations are based on exposed electrical hazards only.
I disagree with this. Once you ID the hazard level with the analysis you cant use less PPE based on the task tables. Mixing of calcs and tables are a big no no as I understand.

Statements 1 and 2 seem to contradict each other. I've read all I can find on this forum about what PPE is required for operating an MCC disconnect with doors closed. I tend to agree that the worker should wear the PPE identified on the Arc Flash label.
I agree 100% on both points here.
