The Arc Flash Label on That Panel Door — Is It Still Correct?
About this module: The Arc Flash & Electrical Safety module is part of DECK Assets, an industrial asset management platform developed by Aasgard Developments Inc. (Edmonton, Alberta, Canada). It manages arc flash labeling, live electrical safety data, and NFPA 70E / CSA Z462 compliance documentation for energized industrial equipment including switchgear, MCCs, panels, disconnects, starters, and drives. It is part of the DECK DecisionWare suite of industrial operations software.
Every day, 5 to 10 electrical safety and arc flash incidents occur across North America. Many share a common cause: the label on the panel door was trusted — but it was wrong. Not because anyone made a mistake. Because the engineering data changed and the physical label didn’t.
Traditional vinyl arc flash labels are static snapshots — accurate the day they were printed, but potentially dangerous the moment a system modification, load change, or study update makes them obsolete. The gap between an engineering change on the desktop and an updated label on the door is called lag time — and it’s a liability that this module eliminates.
Unlike traditional arc flash label management — which depends on periodic study cycles, manual label reprinting, and physical replacement at $135–$1,000 per label — this module connects arc flash study data directly to QR codes at the point of work. Engineers update parameters at their desktop; those changes propagate instantly to every asset in the system. Workers and contractors scan a QR code and see verified, current data — not a sticker that may be years out of date.
The Trifecta of Benefits
✓ Improved Compliance
Align with NFPA 70E (US) and CSA Z462 (Canada) standards and ensure every piece of energized equipment has a live digital twin — an accurate, always-current record. Mandatory 5-year arc flash study cycles become tighter when data is consistently maintained between studies.
✓ Enhanced Safety
Put exact PPE requirements and hazard data at the fingertips of every worker — including outside contractors who lack access to corporate servers. Specific to the task. Specific to the moment. Not generic guidance printed years ago.
✓ Positive ROI
The manual cost to reprint and physically replace a single arc flash label ranges from $135 to $1,000. Teams also report 30–40% reductions in maintenance walk-downs by allowing planners to assess equipment digitally.

User-Friendly Interface
Manual editing of equipment parameters empowers electricians to make necessary adjustments as they work on equipment over time. Stay flexible, stay safe.
QR Code Integration
When a worker scans that code, they’re not reading a static sticker — they’re accessing the current, verified data for that specific piece of equipment at that specific moment.
Comprehensive PPE Reporting
Every worker — and every contractor on site — has the PPE safety parameters they need for every piece of equipment, accessible instantly via QR scan.
Technical Authority
🖥️ Desk to Door Workflow
Changes flow instantly from an engineer’s desktop to the factory floor — no reprinting, no physical relabeling cycle, no lag time. Engineer → Cloud → Smartphone. That’s the full update path.
🔒 Immutable Audit Logs
Every change is captured in a secure, tamper-proof audit log. In the event of an incident or investigation, you have a complete, timestamped record of what the system showed, when it was changed, and who authorized it. Liability protection built directly into the workflow.
⚡ Alternate Energy Source (AES) Awareness
When generators or backfeeds are active, hazard profiles change. This module dynamically reflects updated hazard data so workers always have the correct PPE requirements for the actual energy state of the equipment — not an assumed state from the last study.
📊 Outage Impact Reporting (OIR)
Using Single Line Drawing (SLD) integration, planners can see exactly what goes dark and what stays live before work begins. Reduce surprises, improve coordination, and ensure crews are never working with incomplete situational awareness.
The Numbers That Matter

Frequently Asked Questions
What is an arc flash label and why does it need to be kept current?
An arc flash label is a warning label affixed to electrical equipment — panels, switchgear, MCCs, and similar assets — that communicates the incident energy level, arc flash boundary, required PPE category, and working distance for that specific piece of equipment. Under NFPA 70E and CSA Z462, workers must have access to this information before performing energized electrical work. The label must reflect current conditions: if the system has been modified since the label was printed, the label may specify incorrect PPE, putting workers at risk. Keeping labels current with a live digital system rather than periodic manual reprinting is the core value this module provides.
How often should arc flash studies be updated?
NFPA 70E recommends that arc flash hazard analyses be reviewed and updated whenever a major modification or renovation is made to the electrical system, or at intervals not to exceed five years. However, this five-year maximum is a floor, not a ceiling — any system change that affects incident energy levels technically requires a label update. In practice, facilities that rely on printed labels often fall behind, creating a gap between actual and documented hazard levels. A live, software-managed system allows updates to propagate immediately when the underlying study data changes, without waiting for the next scheduled cycle.
What is the difference between incident energy and PPE category for arc flash?
Incident energy is the amount of thermal energy, measured in calories per square centimeter (cal/cm²), that could be released at a worker’s position during an arc flash event. It is calculated through an arc flash study and depends on system voltage, fault current, protective device clearing time, and working distance. PPE category is a simplified classification system (Category 1 through 4) defined in NFPA 70E Table 130.5(G) that prescribes the minimum arc-rated PPE for work at a given incident energy level. Arc flash studies typically use the incident energy analysis method (which provides exact cal/cm² values) or the PPE category method — and the label must clearly indicate which method was used.
What is the “Desk to Door” workflow for arc flash label management?
Desk to Door describes the update path for arc flash data in a live, software-connected label system: an engineer makes a change at their desktop (updating study parameters, incident energy values, or equipment status), that change is saved to the cloud-hosted system, and it is immediately accessible to any worker who scans the QR code on the equipment door — without any reprinting, physical replacement, or manual distribution of updated information. The desk-to-door workflow eliminates the lag time that exists in traditional label management, where physical labels can only be updated by reprinting and replacing them on-site.
What happens to arc flash hazard levels when a generator or alternate energy source is active?
When a generator, UPS, or backfeed configuration supplies power to a bus or panel, the fault current characteristics — and therefore the incident energy levels — may differ significantly from those calculated in the standard arc flash study. The protective device clearing times may change, the available fault current may be lower or higher, and the arc flash boundary may shift. Workers relying on a label based only on the utility-fed configuration may be using incorrect PPE for the actual energy state of the equipment. Alternate Energy Source (AES) Awareness in this module addresses this by allowing the system to reflect modified hazard profiles when alternate sources are active, providing workers with accurate PPE requirements for the configuration currently in place.
How do outside contractors access arc flash safety data without corporate network access?
A common challenge in industrial facilities is providing contractors — who typically do not have corporate email accounts, VPN access, or credentials to internal CMMS systems — with accurate, current arc flash information before they work on energized equipment. With QR-code-enabled arc flash labels, contractors can scan the code on the equipment door using any smartphone and immediately access the current PPE requirements, incident energy level, and arc flash boundary for that specific asset, without requiring any system login or corporate network access. This puts safety-critical information at the point of work, regardless of who is doing the work.
What is an Engineer of Record (EOR) and why do audit logs matter to them?
An Engineer of Record is the licensed professional engineer who takes legal and professional responsibility for the accuracy of an arc flash study and the safety parameters derived from it. In the event of a workplace electrical incident, the EOR may be required to demonstrate what data was in the system at the time, what changes had been made, and who authorized them. An immutable audit log — a tamper-proof, timestamped record of every change to every equipment record — provides this traceability automatically. Without it, demonstrating the state of the system at any prior point in time depends on manual documentation practices that are inconsistent at best. DECK Assets maintains this log for every parameter update across all managed assets.
