Arc flash incidents can happen in a split second, but the right preparation can make all the difference. In this episode of The Deep Dive, we break down the must-know insights from the article “Optimizing Arc Flash Protection: The Crucial Role of Layered Clothing” by Derick Sang, featured in Incident Prevention Magazine. From flame-resistant undergarments to outerwear strategy, we explore why a layered clothing system isn’t just safer — it’s smarter. Learn how layering improves protection, comfort, compliance, and even day-to-day adaptability in the field. Whether you’re in safety leadership or on the front lines, this episode delivers actionable takeaways you can put to work today.

✅ Key Takeaways:

  1. Layered Clothing Enhances Protection: Combining base and outer layers boosts defense against arc flash energy more effectively than a single garment.

  2. Comfort & Moisture Management Matter: Layering helps regulate temperature and sweat, improving field comfort.

  3. Compliance Isn’t Optional: OSHA, NFPA 70E, and ASTM standards mandate FR/AR clothing and recognize layering as an effective strategy.

  4. Base Layers Are Often Overlooked: FR-rated undergarments are critical for secondary protection and shouldn’t be substituted with just cotton.

  5. Training & Maintenance Are Vital: Proper education on wear and care ensures PPE is used correctly and continues to perform over time.

❓ Five Questions & Answers:

Q1: Why isn’t a single flame-resistant garment enough in high-risk environments?

A1: While common, single layers can be uncomfortable and might not meet protection needs. Layering offers cumulative protection and energy dissipation.

Q2: What role do FR base layers play in arc flash safety?

A2: They act as a secondary defense, especially if outerwear shifts or fails during an event, protecting the skin and helping prevent burns.

Q3: Are layered systems recognized by safety standards?

A3: Yes. OSHA, NFPA 70E, and ASTM F1506 all support layered approaches and place responsibility on employers to provide proper gear.

Q4: How does layering improve comfort for utility workers?

A4: It regulates body temperature and wicks away moisture, keeping workers dry and more comfortable throughout changing weather conditions.

Q5: What training should accompany an FR layered clothing system?

A5: Workers should be taught how to wear layers properly, understand when PPE is required, and avoid compromising safety by adding non-FR outerwear.
