Table Assessment and Arc Flash Study

Don't let budget limitations stand in the way of electrical safety. Our team of electrical safety experts can help determine if your workplace equipment meets the requirements of OSHA and NFPA 70E - 2015. e-Hazard's electrical industry professionals can provide table-based recommendations for any workplace situation at an affordable price.

Table Assessment

e-Hazard can help you create arc flash equipment labels based upon NFPA 70E or CSA Z462. In most cases, a one-day site visit will identify if your company meets all table requirements or is in need of an arc flash study. Many smaller facilities with one utility feed and less than a 1500 KVA transformer do not need a full engineering study and can save thousands of dollars with a table assessment.

Our Professionals

Our electrical safety professionals can provide table-based recommendations for your company. We will determine if equipment meets the table requirements of NFPA 70E and help you create labels based upon NFPA 70E. We can also provide training on the use of tables. If hazards are present, our electrical safety specialist will determine if an arc flash study with calculations is needed.

Case Study

A large warehouse will frequently only need arc flash calculations for the main switch gear while the rest of the facility may be in compliance with the tables. During a site visit, an e-Hazard professional engineer can make this determination and label the piece of non-compliant equipment. Afterwards, you will be guided through labeling the remaining equipment at a more budget friendly cost than a full arc flash study.

Evaluations are available for:

NFPA 70E, CSA Z462 Arc Flash Table Based Assessment or NESC Assessment

  • Personal Protective Equipment (PPE)
  • Arc Flash Equipment Labeling
  • Equipment Specific Lockout/Tagout Program Writing (optional)

Arc Flash Study

Arc flash hazard calculations can be complicated. e-Hazard delivers the necessary results of an arc flash study performed by one of our Professional Engineers (PE) using multiple methods of evaluation. Data can be gathered by your personnel, e-Hazard personnel or a third party contractor.

e-Hazard provides comprehensive engineering studies including:

  • Full, on-site evaluation
  • Modeling
  • One-line drawing
  • Fault current
  • Coordination studies

Our Professionals

Our professional engineers are members of the committees setting the standards for arc flash studies. These include NFPA 70E, IEEE 1584 and IEEE P1584.1. e-Hazard uses SKM Power Tools, EasyPower, ETAP, EDSA, ArcPro and other software packages to provide the best, user friendly results for your arc flash equipment labels.

The Results

Once the study is complete, e-Hazard will make recommendations to reduce any arc flash hazards by changing breaker settings, fuse types and other methods to mitigate the possible effects of arc flash. e-Hazard also provides you with the digital files of your arc flash study for reference when updates are necessary. Arc flash studies are required to be audited every 5 years by NFPA 70E/CSA Z462. Owning the digital files allows you to audit your study internally or to get a second opinion of an outside engineering firm.
