Arc Flash PPE Requirements Chart Explained
Arc Flash PPE Requirements Chart is a vital resource for electrical safety professionals seeking a clear and visual breakdown of protection standards. Based on NFPA 70E guidelines, this chart aligns incident energy exposure levels with the required arc-rated (AR) protective equipment for each task. Whether you're assessing hazard levels or planning worker PPE, the chart provides task-based clarity—helping safety managers match the correct personal protective equipment with each job’s unique risk.
If you're working with high-calorie protection suits, our 40 Cal Arc Flash Suit page offers an in-depth look at components, compliance, and use cases. With categories ranging from 4 to 40 cal/cm², this tool ensures compliance, reduces injury risk, and supports smarter, faster PPE selection in energized environments. Explore the complete PPE framework outlined by workplace safety standards in our Arc Flash PPE Requirements page, covering selection, compliance, and risk assessment.

Understanding the Arc Flash PPE Categories
NFPA 70E categorizes hazards into distinct PPE levels, each associated with a specific range of incident energy measured in calories per square centimeter (cal/cm²). Our chart provides a visual representation of these categories, detailing the required PPE for each level to ensure workers are adequately protected. To better understand how each PPE category is defined, visit our detailed guide on the Arc Flash PPE Category page, which explains hazard levels from Category 1 to Category 4.
According to Table 130.7(C)(15) in the NFPA 70E standard, the appropriate PPE is determined based on the task and the associated incident energy exposure. For tasks with a rating of 25 cal/cm², workers are typically required to wear a complete AR ensemble that includes a shirt and pants or coverall system made from flame-resistant materials. In addition to clothing, face shields are an essential part of head and facial protection, offering a barrier against radiant heat and flying debris during an incident energy event. Proper selection of PPE from this table ensures compliance and significantly reduces the risk of injury in hazardous electrical environments.
Key Features of the Chart:
-
Visual Representation: The chart uses intuitive graphics to depict each PPE category, making it easy to understand the required protective gear at a glance.
-
Detailed Descriptions: Each visual is accompanied by a concise description of the PPE components necessary for that category, including clothing, headgear, face protection, and gloves.
-
Compliance Guidelines: The chart aligns with the latest NFPA 70E standards, providing up-to-date information to help organizations maintain compliance.

How to Use the Chart:
-
Identify the Hazard Category: Determine the task or equipment's hazard category based on an incident energy analysis or the PPE category method.
-
Consult the Chart: Refer to the corresponding section of the chart to view the required PPE for the identified hazard category.
-
Equip Accordingly: To mitigate the risk of injury, ensure that all personnel don the specified PPE before commencing work.
Matching PPE to Incident Energy Levels
Selecting the proper AR gear begins with identifying the electrical hazard protection levels outlined in the NFPA 70E PPE matrix. This matrix helps map out task-based protection, ensuring that the required gear by incident energy matches the severity of the exposure. Whether the task involves energized equipment or maintenance near switchgear, clothing requirements by cal/cm² serve as the benchmark for choosing the right level of PPE. Selecting the correct AR suit, gloves, or face shield meets regulatory requirements and ensures workers remain protected based on the actual energy risk present.
