Arc Flash PPE Category Selection Chart — IEEE 1584-2018 & NFPA 70E
Free download · A4 portrait, wall-poster
Selecting the correct arc flash PPE category is a life-or-death decision. This A4 portrait wall poster presents the four NFPA 70E PPE categories in a clear, colour-coded layout that can be read from across a switchroom. Each category band — Category 1 (green, 1.2–4 cal/cm²), Category 2 (yellow, 4–8 cal/cm²), Category 3 (orange, 8–25 cal/cm²), and Category 4 (red, 25–40 cal/cm²) — lists the minimum required PPE: arc-rated shirt and pants, face shield, balaclava, flash suit hood, and glove ratings. Above 40 cal/cm² is marked as a red DANGER zone where energized work is prohibited. The poster includes the IEEE 1584-2018 simplified arc flash boundary formula, approach boundary distances (limited, restricted, prohibited) per NFPA 70E Table 130.4(E)(a), and a decision flowchart for determining whether energized work is justified. Post this in every switchroom, MCC room, and electrical workshop. Pair with our arc flash calculator to determine exact incident energy levels for your specific equipment configurations.

Frequently Asked Questions
Where should I post this chart?
Post in every switchroom, MCC room, electrical workshop, and PPE storage area. Laminate for durability. NFPA 70E requires arc flash hazard identification at equipment — this chart supports that requirement.
What paper should I print this on?
Print on A4 in colour — the colour coding is critical for quick PPE category identification. Use a colour laser printer for durability. Laminate and mount on the wall.
What standard does this reference?
This chart references IEEE 1584:2018 for incident energy calculation methodology and NFPA 70E for PPE category definitions, approach boundaries, and energized electrical work permit requirements.
How often is this updated?
Updated when IEEE 1584 or NFPA 70E publishes new editions with revised PPE categories or boundary distances. Current chart reflects IEEE 1584:2018 and NFPA 70E:2024.
