Arc Flash Labels — OSHA & NFPA 70E-Compliant

Yes. NFPA 70E requires that electrical equipment be field-marked with arc flash hazard labels where an arc flash hazard exists. The standard specifies that labels must include information such as incident energy, arc flash boundary, required PPE, and working distance. Employers are responsible for conducting hazard assessments and applying compliant labels to all applicable equipment.

Under NEC 2026 (Article 110.16), electrical equipment must be field-marked to warn qualified persons of potential arc flash hazards. Labels must include nominal system voltage, arc flash boundary, and at minimum the available incident energy or the required PPE level. The NEC requires this marking on equipment likely to require examination, adjustment, or maintenance while energized.

The primary NEC code for arc flash labels is Article 110.16, which mandates arc flash hazard warning labels on electrical equipment in commercial and industrial settings. It requires field-applied labels on switchboards, switchgear, panelboards, industrial control panels, and motor control centers that are likely to require examination or servicing while energized.

Arc flash labels from Shield and Supply are available in durable vinyl, high-temperature, and reflective materials rated for 5–10 years of indoor and outdoor use. These materials are scratch-resistant and chemical-resistant, ensuring label legibility and adhesion even in harsh electrical room environments exposed to solvents, heat, or moisture.

Yes. With a LabelTac industrial label printer and the included LabelSuite Design and Print Software, you can create fully customized, NFPA 70E-compliant arc flash labels on demand. Labels can be printed in widths from 1/2" to 9" and in multiple colors including high-visibility options to match your facility's specific hazard identification requirements.

Per NFPA 70E, arc flash labels must include: the arc flash boundary, the incident energy level and working distance (or the PPE category), the nominal system voltage, and the shock protection boundaries. Some facilities also include the equipment name, date of study, and responsible engineer. Labels must be legible, durable, and field-applied to the equipment.
