ARC-FLASH HAZARD ANALYSIS

An arc-flash hazard analysis is an engineering study that calculates incident energy levels throughout a facility so appropriate PPE can be
selected by electrical workers. Upon completion of an arc-flash hazard analysis, arc-flash hazard warning labels are provided that are then posted
on the facility’s electrical equipment. The facility also receives an engineering report that documents the methodology used for the study, describes the study’s findings, makes recommendations to improve the facility’s electrical safety and provides a current one-line diagram.

IMPACT OF A
WORKPLACE
INJURY

An arc-flash event can cause third degree burns and potential death as well as other injuries including blindness, hearing loss, nerve damage and cardiac arrest. The National Safety Council estimates a major work-related injury can cost a business over $10M in fines, litigation, medical costs, loss of business and equipment repairs.

THE PROCESS

Detailed information of a facility's electrical system is required before an electrical study can begin. Site specific information can be provided in the form of drawings, submittals, or by other means. If detailed information is not readily available, it can be collected in the field by our technicians, your in-house electricians or your preferred contractor. Entire shutdowns are often required to safely collect information needed for the study.

After system data is collected, an engineer builds an electrical system model within specialized engineering software. An arc-flash hazard analysis is performed in conjunction with an electrical short-circuit study and protective device coordination study. These additional studies verify that the electrical equipment is adequately sized and properly set.

NFPA 70E

The NFPA 70E provides the formal requirement for the arc-flash study and specifies PPE, working distances and shock hazards shown on the labels. IEEE 1584-2018 formulas are used to calculate the theoretical arc-flash energy which is also displayed on the arc-flash labels.

The NFPA 70E requires arc-flash studies to be revised every 5 years or after any significant electrical upgrade.

Electrical arc-flash is considered by OSHA to be a recognizable hazard that must be mitigated.

It's important to our clients that we provide high quality engineering services with quick turnaround at a competitive price so that's what we do!

SEL RELAYS

We provide engineered solutions for replacing outdated relays with new SEL relays that provide better troubleshooting capabilities, arc-flash reduction, better system visibility and more protective functions that outdated electrical-mechanical relays do not.

 

We work with clients on high voltage substations with protection design, relay settings, post-fault investigations and troubleshooting.

For MV motor starter upgrades we replace the existing controls with a SEL 710 relay which allows for current based transfers and advanced troubleshooting capabilities.
