Arc Flash Risk Assessment

Step 1 – On-Site Data Collection


Arc Flash Risk Assessment identifies potential electrical hazards.The arc flash risk assessment identifies the presence and location of potential hazards and provides recommendations for PPE, boundaries for limited, restricted and prohibited approaches, recommendations for flash protection, and safe work practices.

An ESS arc flash Engineering Technician will come on-site to collect the necessary information to perform an Arc Flash Risk Assessment which is a critical step in the process. Our arc flash Engineering Technicians have several years of experience in commercial/industrial electrical installations and maintenance, they also have extensive training on the intricacies of the data collection process for Arc Flash Risk Assessment, Selective Coordination, Equipment Evaluation, just to name a few.

It is imperative that we get the correct information needed to perform an Arc Flash Risk Assessment in your facility. Many factors such as conductor size/length, over current protection device (i.e. breakers, fuses), settings, transformer sizes and impedances, as well as looking for all areas requiring labels per NEC, NFPA 70E, IEEE will be documented and physically verified on-site. This will require opening of panel covers, MCC buckets, Industrial control panels, and more. Our Engineering Technicians are comprised of Master/Journeyman electricians that are thoroughly trained to achieve the data collection without disrupting power. In the very rare occurrence that power will need to be disrupted we have several options availab le to gather the necessary information to perform the Arc Flash Risk Assessment.

Step 2 – Arc Flash Engineering Analysis

Flow chart for arc flash engineering analysis.Once the data collection process is complete, we will begin the process of creating arc flash one line diagrams and conducting a hazard risk assessment including arc flash, shock hazard, short circuit assessment, and coordination studies. We also offer mitigation studies (Optional) to help reduce the arc flash hazards to a manageable level. We usually suggest mitigation as a service to be done only if needed. Find out your levels of risk before you try to fix them.

As an independent consultant we do not pursue or generate revenue by selling breakers, fuses, and switchgear as many of our competitors do. We strongly believe "if it is not broke, don't fix it". The purpose of our visit is to help save lives and money by safe work practices and minimize the possibility of injuries and lost time accidents.

Step 3 – Installation of Arc Flash Warning Labels

Arc Flash Technician installs arc flash warning labels.This will be the second visit to your facility. One of our arc flash Engineering Technicians will apply the arc flash warning labels generated by the arc flash study. This is another critical step in the process as it is imperative to insure that the arc flash warning labels are placed in the correct locations, as a misplaced label could mean life or death in the wrong situation.

NFPA 70E 130.5.

Electrical equipment such as switchboards, panel-boards, industrial control panels, and motor control centers that are likely to require maintenance while energized, must be field marked with a label.

Step 4 – NFPA 70E Arc Flash Training

Arc Flash Risk Assessment includes arc flash safety training for employees.Once again critical steps in performing an Arc Flash Risk Assessment. All the efforts thus far will be meaningless unless your employees are able to follow and understand the guidelines set forth by OSHA, NFPA70E, NEC, and IEEE. Our goal is to save lives and this will not be possible if your employees are not actively engaged in the process and safe work practices set forth by your company. This step is usually completed during the arc flash labeling application process or during the data collection process if your company desires.
