ARC FLASH ANALYSIS

Why should I perform an Arc-Flash Analysis?

Without an Arc-Flash Analysis, you cannot protect your employees from an arc-flash. It is imperative to know realistic values for fault current as well as clearing time for protective devices in order to determine the proper Personal Protective Equipment (PPE) for your electrical workers. Guessing or assuming an infinite bus can be dangerous! Only a complete system analysis allows for proper hazard assessment and recommendations for the appropriate Arc-Flash Protection.

Are there regulations regarding Arc-Flash Protection?

Indeed there are. OSHA 29 CFR 1910.132 (d) requires employers to assess the workplace to determine if hazards are present and select and require each employee to use the types of PPE that is needed to protect them from the hazard……...Verify that the required workplace hazard assessment has been performed through written certification that identifies the particular workplace evaluated.

NFPA 70E-2004, Article 110.8 (B) (1) (b) states that a flash hazard analysis shall be done in order to protect personnel from the possibility of being injured by an arc-flash. The risk analysis shall determine the level of the hazard and the proper rating of the PPE for the given task.

In performing an Arc-Flash Analysis, what is the Proper Procedure?

Gathering Electrical System Data and Site Assessment
Short Circuit Study on the Electrical System
Protective Device Coordination Study
Evaluation Analysis of Electrical Equipment
Arc-Flash Hazard Analysis and Equipment Labeling

Arris Engineering has recently been awarded another design project at the Tobyhanna Army Depot. The renovations and additions to the Building 72 Mezzanine area marks the fifth project awarded this year. Arris will act as the lead design professional for this project and will work with M.E.R.I.T. Inc. in a design/build capacity to complete construction of the renovation and addition.

Arris has implemented Autodesk Revit MEP. The new software has allowed Arris to work with Architects that also utilize the Architectural version of the software and better serve to meet the client’s needs when considering a complete building system package. The software conversion included all the aspects of Autocad MEP and also allows for designs to be completed with the use of 3-D building components.
