When selecting arc flash PPE, a common question arises: should you opt for a one-piece coverall or a full arc flash suit (jacket + bib + hood)? Each has its advantages depending on the application and environment.
Arc Flash Coverall
- Design: One-piece, zipper closure
- Use Cases: Quick wear, confined spaces
- Advantages:
- Less room for error in donning
- Lightweight and compact
- Disadvantages:
- Less flexible in hot environments
- Limited layering options
Arc Flash Suit (Jacket + Bib + Hood)
- Design: Modular; allows for partial wear
- Use Cases: Utility substations, transformer rooms, maintenance work
- Advantages:
- Better heat ventilation
- Easy replacement of one part (e.g., just the jacket)
- Disadvantages:
- Takes more time to wear
- Slightly heavier
