We conduct Arc Flash Risk Audits/Assessments for our customers with support from Brady ID Technical Services teams.

What is Arc Flash Risk?

Arc flash (often called a flashover) is a type of electrical explosion or discharge that results from a connection through air to ground or another voltage phase in an electrical system. For example, when a wire makes contact with an earthed system. Temperatures at the source of an arc flash can reach 20,000 °C — around four times the surface of the sun.

Injuries can include external burns (i.e. severe burns to the skin), internal burns and intoxication from inhaling hot gasses and vaporised metal, hearing damage, eye damage and blindness from the ultraviolet light of the flash as well as many other devastating injuries.

Arc Flash Risk Assessment
Dedicating internal resources to complete your NFPA Arc Flash Risk Assessment can not only be time
consuming, but requires an investment in software and the Arc Flash knowledge behind the assessment.
One miscalculation can result in inaccurate PPE protection, non-compliance and even more time spent on rework. Our Electrical Engineer will complete your assessment, provide you with a detailed assessment report including your single line diagram and install the correct arc flash labels.
Our Arc Flash Risk Assessment is performed by a licensed Engineer using power system analysis software, providing you with the tools and resources for success. From performing the risk assessment and printing the proper arc flash labels, to collaboration with your stakeholders and a detailed assessment report, our engineers will enable you to not only reach compliance, but maintain compliance.

The Process:
• Brady engineers will hold a kick off meeting that will include team building with your internal
stakeholders and a facility tour
• Brady engineers will then collect and audit your arc flash data including identifying all electrical
equipment, documenting conductor lengths and ampacity, documenting overcurrent protection
device ratings and more
• Once all the data is collected, they will enter the information into the power system analysis
software creating an electrical system single-line diagram
• With all information in hand our engineer will create your risk assessment report and create the
corresponding arc flash labels
Standards Included NFPA 70E, IEEE 1584

Arc Flash Audit, On Site & Off Site Activities (Phase-1 & Phase -2)

Phase 1 (Visit 1): Arc Flash Analysis: Brady Electrical Engineers will visit for on-site data collection to
accomplish below objectives –
1. Single Line diagram
Power Flow Representation from the Grid ( Power Supply ) to the End Load
2. Load Flow Study
Study to Assess the Cable Capacity, Load Bearing Capacity and also the Device Load withstanding
Capacity
3. Short circuit Report (Alert summery and Marginal report will be given along FCT Value)
Study to Assess if the System is Capable of withstanding the Short Circuit.
4. Device Setting
Detailed report of the Settings on the Breakers /Devices.
5. Relay Coordination Verification
6. Study Carried out to find out if the Sequence of Tripping is from Bottom Load to the Source of
Power
7. Arc flash Report
Study used to find out the respective Category of PPE required to work on the assessed Panels.

accomplish below implementation objectives –

1. Development of SOP for different levels of PPE
2. Customised Training for Staff
3. Submission of Reports:
I. Single Line Diagram (pdf)
II. Short Circuit Report (pdf)
