This article aims to analyse the electric arc exposure hazards to human health and to develop proposals for improvement of safe operation of electric equipment in organizations. The study is carried out on the situation in the field of regulatory documents governing the safe operation of electric equipment; moreover, recommendations are also given. It is concluded that the standard IEC 61482-1-2 (LVS EN 61482- 1-2) is adapted in the Republic of Latvia, which puts forward the requirements to protective clothing against electric arc exposure, but this standard only takes into account the spectrum of partially served electric devices. It is, therefore, necessary to introduce the international standard IEC 61482-1-1, which takes into account the actual short-circuit current magnitude and environmental layout of electric devices.
