NFPA 2112 vs NFPA 70E: A Practical Comparison

If you buy FR clothing for oil, gas, chemical or electrical work, you have seen both NFPA 2112 and NFPA 70E on labels and quotations. They are often listed together, but they cover different hazards and different test methods. Understanding the difference makes specifications clearer and audits easier.

NFPA 2112 in one paragraph

NFPA 2112 is the standard for flame-resistant garments protecting industrial workers from flash fires. Garments are tested on an instrumented manikin and must limit predicted body burn to 50% or less, plus pass heat and flame tests after laundering. It is the standard most oil and gas operators cite.

NFPA 70E in one paragraph

NFPA 70E is the electrical safety standard for the workplace. It requires arc-rated clothing for electrical work, based on an incident energy analysis. Arc ratings come from ASTM F1506 fabric testing and are expressed in cal/cm². The standard also sets PPE categories and risk assessment procedures.

Where they overlap and where they do not

• A garment can be both NFPA 2112 compliant and arc-rated. Many arc-rated shirts are dual-certified.
• NFPA 2112 alone says nothing about arc performance.
• NFPA 70E alone does not guarantee flash fire performance; it focuses on arc ratings.
• For mixed hazards, specify a garment that meets both.

How the labels differ

An NFPA 2112 label typically states “NFPA 2112 compliant” and may reference the fabric certification. An arc-rated label must state the arc rating in cal/cm² along with the standard, and often the PPE category.

If you are building a specification, list the standard, the year and the required performance number — for example, “NFPA 2112 compliant, arc rating 12 cal/cm², ASTM F1506”.

What this means for procurement

1. Ask what hazard dominates. Flash fire, arc flash, or both.
2. Require documentation for each standard. A certificate for one does not cover the other.
3. Check trims and layers. Zips, reflective tape and embroidery thread must also be FR for FR garments.
4. Align outerwear. Winter jackets and rain gear in an FR zone must be FR-rated.
5. Plan laundering. FR performance depends on care; industrial laundry programs need compatible detergents and procedures.

Common scenarios

Oil and gas site: NFPA 2112 shirts, pants, coveralls and jackets, often with FR hi-vis. Arc ratings are usually not the driver unless electrical work is in scope.

Electrical utility: Arc-rated clothing to NFPA 70E, with ratings matched to incident energy. FR hi-vis is common for roadside work, and rain gear must be FR.

Mixed industrial plant: Dual-certified garments simplify inventory, because one shirt covers both hazards.

Documentation checklist for buyers

• Fabric and garment certificates for NFPA 2112
• Arc rating reports (ATPV) for arc-rated styles
• Care and laundering instructions
• Lot or tracking codes
• Declarations of conformity for CE markets

Bottom line

NFPA 2112 addresses flash fire, NFPA 70E addresses arc flash, and the strongest programs specify dual-certified clothing where both hazards exist. Ask for the certificate that matches the hazard, not just the standard name on the marketing sheet.
