Causes of Arc flash:
- Inadequate maintenance.
- Wear and tear.
- Accidental dropping of uninsulated tools.
- Equipment failures.
- Live work on damaged equipment.
- Exposed live parts.
- Loose connections.
- Lack of training and awareness.
Our approach for arc flash assessment:
- Understand the legal and regulatory requirements for electrical and workplace safety.
- Safety practices compliance with relevant standards – NFPA 70E, OSHA.
- Goals for electrical safety, considering both personnel and equipment protection.
- Perform a thorough risk assessment.
- Identify potential hazards and quantify the risks.
- Define engineering controls, administrative controls, and PPE.
- Provide detailed plan for implementing potential measures.
- Training and awareness for electrical and non-electrical team.
Our deliverables:
- Determine the information required to perform the study by site survey and data collection based on the task matrix.
- Guidance on the accuracy of data collection and information required.
- Updating of Power distribution single line diagram.
- Listing of electrical equipment within the scope of study.
- Determine system modes of operation.
- Review of short circuit study and protective relay coordination report provided by customer.
- Arc flash hazard calculations.
- Representation of incident energy test results.
- Evaluable with tolerable limits provided by standards.
- Optimization of protective devices.
- Consideration of incident energy reductions.
- Arc flash label design and information.
- Training and discussion on report.
