Arc Flash Hazard Analysis
The Bureau of Labor Statics tells us that more than 2,000 people each year are injured in arc flash accidents. This means that everyone of these persons was admitted to the hospital for at least 24 hours with serious burns. As you know, America’s electrical grid is changing. That change means the hazards your employees face increase. The National Fire Protection Association (NFPA) has mandated; with few exceptions that all employers perform an arc flash hazard analysis of their electrical system.
What is an arc flash?
An arc flash is the instantaneous release of massive electrical energy that is the result of an electrical short. Temperatures of 35,000 degrees Fahrenheit can be generated. If people are near this explosion, they can be badly injured or even killed by the fire, electric shock, shrapnel and blast.
Benefits of arch flash hazard analysis
- Compliance with NFPA 70E standards.
- Greatly increased safety for your personnel.
- Greatly increased electrical system reliability.
- Workman’s compensation costs kept in check.
- Reduced liability and lost production.
- Improvement of a company’s image as a good corporate citizen.
Mandated by the National Fire Protection Association
As a part of our service we urge you to consider onsite training for personnel who are tasked with working on or maintaining electrical equipment. Our training insures that you and your personnel understand arc flash and the proper care and use of PPE. Additionally, we teach your employees the following: how to protect other employees who may be exposed to arc flash; how to establish and maintain the four hazard boundaries; how to establish an electrically safe working condition and much more.
We survey your facility’s electrical system, beginning at the electrical utility, then the electrical service, the main distribution system(s), all panel boards, all disconnect switches, motors of 50 horsepower and larger, onsite generators, the wiring and all systems covered under NFPA 70E.
We produce truly accurate one-line drawings of the electrical system (the electrical backbone of your system) then:
- We calculate the maximum possible fault currents throughout the system.
- We identify the locations where arc faults are possible.
- We determine real-world solutions to reduce arc flash and arc flash hazards.
- We provide and produce the mandatory ANSI labeling with the hazards and we permanently attach them to your equipment.
- We produce a complete report that includes the Short Circuit Study, the Coordination Study, hard copies and soft copies of all the work product and we produce CAD one-line drawings of your system.
- The above mentioned documents are bound into a report and delivered to you.
- We thoroughly review the findings with you.
- We explain everything the report contains so you fully understand the results.
- And your report in written non technical language, so you can maximize your use of this information.
What’s the cost?
Unfortunately, we can’t give you an accurate cost until we see your facility, but our clients tell us our prices are surprisingly low.
We’re pleased to hear that because we try very hard to ensure our clients receive the best quality arc flash hazard analysis. One that truly serves the clients needs.

Frequently asked questions
The electrical service on our building is only 400 amps but is 480 volts. Are we required to get an arc flash hazard survey?
We have 2 services on our facility. One is 3000 amps and the other is 1200 amps. Can we do one at a time? Or must we do them both?
Our building is pretty old. I’m not sure what the power voltage is or how large it is. How can I determine if I need to get arc flash done?
Our building is 75 years old and most of the electrical system is original. I’ve looked and not much of it has labeling left on it. Do we need an arc flash and what do you do with places like this?
Our facility is not on the utility grid so we power our site with three 750 KVA natural gas generators. Do we have to get arc flash?
We just had an arc flash done about 10 years ago but I’m not sure if it’s still okay. OSHA was here a few years ago and didn’t say anything then. I think were due for another inspection. I’ve heard that OSHA is starting to crack down on Arc FLASH. Am I okay?
I am responsible for a large health care facility. The hospital has two 3000 amp services with an automatic tie breaker between them so if one service fails, the tie breaker automatically connects the dead service to the live one. Can you do arc flash for this kind of system?
I noticed that the 1600 amp breaker on our generator has dials that we can set. One says LT delay. What does LT mean?
