7.1 Arc Flash Hazard
IEC 61936 requires arc mitigation if prospective energy > 300 kJ (≈ 25 kA for 0.2 s).
Mitigation methods:

7.2 Personal Protective Equipment (PPE)

A common mistake: even if the conductor is hot (energized), the structure around it must be earthed. IEC 61936 requires that portable earthing devices are rated for the prospective fault current and the duration of the hot work. If a hot conductor falls on an ungrounded structure, the step voltage kills. iec 61936 pdf hot

This paper summarizes IEC 61936 requirements relevant to high-voltage electrical installation safety, with emphasis on thermal and "hot" conductor scenarios (overheating, fault heating, energized component handling). It outlines applicable clauses, risk-assessment methodology, design and protection measures, testing and verification, and recommended best practices for installation, maintenance, and emergency response. design and protection measures
