GB/T 41092-2021 is the English-translated version of 多重应用环境场所电气安全风险评估和风险降低指南.
GB/T 41092-2021 is guidance on assessing and reducing electrical safety risks in multiple application workplaces, that is, sites where several electrical equipment and systems of different kinds work together and can disturb one another's electric and magnetic fields and heat distribution.
It sets general principles and implementation steps, then explains how to determine the application subjects and their correlation, identify hazards and safety factors, estimate risk with a risk index, evaluate it, reduce it and reassess it, and how to document the work.
Its annexes list the safety factors that application subjects share and those that differ between them. It applies to electrical equipment and systems of 1000 V AC and below and 1500 V DC and below in such workplaces. It was issued on 31 December 2021 and has applied since 1 July 2022.

Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1. Structure and Drafting Rules of Standardization Documents" drafted.
Introduction
With the development of technology and changes in demand, more and more application subjects (all kinds of electrical equipment and systems) are integrated into a workplace. We refer to such workplaces as multi-application environments.
Due to different functions, the mutual influence between the application subjects may lead to the instability of electric field, magnetic field and thermal distribution, which will affect the site and application main body.
The safety of the body creates uncertainties. Through risk assessment and risk reduction, it is possible to identify hazards, determine risk levels, and control risks. Purpose.
1 Scope
This document provides guidelines for the implementation of electrical safety risk assessment and risk reduction in multiple application environments, including general principles, implementation steps, application subject determination, identification of application subject safety factors, risk estimation, risk assessment, risk reduction, reassessment and document preparation.
This document is applicable to all kinds of electricity with AC voltage of 1000V and below and DC voltage of 1500V and below in multiple application environments safety risk assessment and risk reduction of gas equipment and systems.
