Know the Energy, Boundaries and Protection Required at Each Location

An arc flash study evaluates the electrical distribution system to calculate potential incident energy, determine arc flash boundaries and provide location-specific information used to support safer work practices and equipment labeling. Every InfraredTeam arc flash study is engineered and sealed by a licensed Professional Engineer from our vetted engineering partner. Our team handles the field data collection, verification, coordination and reporting.

  • Protective-device clearing times
  • Incident energy at working distance
  • Arc flash boundaries
  • PPE or energy information for equipment labels
  • Mitigation opportunities at higher-energy locations

Common Reasons Organizations Start or Update an Arc Flash Study

No Current Arc Flash Study

The facility has never completed a location-specific arc flash hazard analysis.

Study Is Five Years Old or Older

The electrical system and labels may need review as part of the facility’s electrical safety program.

Electrical System Changes

New transformers, equipment, protective devices or system reconfiguration can change the model and results.

Missing or Generic Arc Flash Labels

Existing labels may not provide equipment-specific incident-energy or boundary information.

New Construction or Renovation

Study, documentation and labeling may need to be coordinated with project closeout.

Audit, Insurance or Safety Review

A review may identify gaps in electrical safety documentation or labeling.

Clear Engineering Deliverables for Your Facility Team

Reports
Depending on the agreed project scope, deliverables may include:
  • Stamped arc flash hazard analysis report
  • Short-circuit analysis results
  • Protective-device coordination study and time-current curves
  • Updated or newly developed one-line diagrams
  • Equipment-specific arc flash labels
  • Prioritized mitigation recommendations
  • Documentation for internal safety, insurance and project review
  • Digital copies of reports, diagrams and label data
NOTE: Final deliverables and stamping requirements are defined by project scope and may vary by jurisdiction.

Outdated Arc Flash Data Can Lead to the Wrong Work Decisions

Workers may not have location-specific information for selecting protective measures.
Electrical system changes can make older calculations and labels inaccurate.
Generic labels may not communicate equipment-specific incident energy or boundary data.
Missing documentation can create delays during audits, project closeout or insurance review.
Poor protective-device coordination can increase equipment damage and outage duration.
Arc flash programs may involve NFPA 70E workplace electrical safety practices, IEEE 1584 calculation methodology and applicable NEC marking requirements. Requirements and final documentation depend on the facility, project and jurisdiction.

Analysis Identified Opportunities to Reduce Incident Energy

ENGINEERING OUTCOME

During an industrial arc flash study, the engineering study identified locations with elevated incident-energy levels related to protective-device clearing times. The team recommended coordination and relay changes intended to reduce exposure at those locations and improve the facility’s electrical safety planning.

Arc Flash Study FAQs

How often should an arc flash study be updated?
Arc flash studies should be reviewed when electrical-system changes could affect fault current, protective-device clearing time or system configuration. InfraredTeam’s source material also references a five-year review cycle associated with NFPA 70E guidance. The appropriate timing should be confirmed for each facility and electrical safety program.
Who needs an arc flash study?
Organizations whose personnel work on or near energized electrical equipment may need a location-specific hazard assessment and equipment labeling as part of their electrical safety program. Requirements depend on the facility, work practices and jurisdiction.
What is included in a comprehensive arc flash study?
A typical scope may include field data collection, one-line verification, short-circuit analysis, protective-device coordination, incident-energy calculations, equipment labeling and an engineering report.
How long does an arc flash study take?
Timing varies with facility size, system complexity and available documentation. Field collection may require one to several days, followed by engineering analysis, review, reporting and labeling.
What does an arc flash study cost?
Pricing depends largely on electrical-system size and complexity, including the number of modeled buses, buildings, voltage classes, existing documentation and field-verification requirements. InfraredTeam provides a scoped proposal after an initial discussion.
Can InfraredTeam update an existing arc flash study?
Yes. When reliable models, reports and one-line diagrams are available, InfraredTeam may be able to verify system changes and update the existing study rather than rebuild the entire analysis.
What is the difference between NFPA 70E and the NEC?
NFPA 70E addresses workplace electrical safety practices, while the National Electrical Code addresses electrical installations and marking requirements. The requirements that apply to a specific project should be confirmed based on the facility and jurisdiction.
