This document specifies methods for identifying and assessing hazardous situations that may lead to explosions, as well as design and structural measures that are consistent with safety requirements, through the following aspects: - Risk assessment; - Risk reduction. Safety of equipment, protective systems, components can be achieved, by eliminating hazards and/or limiting risks, i.e., by: a) Proper design (no safety protection devices); b) Safety protection devices; c) Usage information; d) Any other precautionary measures. Explosion protection measures corresponding to a) (prevention) and b) (protection) are covered in Chapter 6. Explosion protection measures corresponding to c) are covered in Chapter 7. The explosion protection measures corresponding to d) are not covered in this document. They are covered in GB/T 15706 (Chapter 6 in GB/T 15706-2012). The preventive and protective measures, which are specified in this document, can only provide the required level of protection, when the equipment, protective systems and components are operated within the scope of their intended use and are installed and maintained in accordance with the corresponding operating procedures or requirements. This document specifies general design and manufacturing methods, to help designers and manufacturers achieve explosion-proof safety, when designing equipment, protective systems, components. This document applies to any equipment, protective systems, components, which are intended to be used in explosive atmospheres under atmospheric conditions. These environments may be caused by flammable substances that are handled, used or released by equipment, protective systems, components, OR by flammable substances around equipment, protective systems and components and/or by the constituted GB/T 25285.1-2021 www.ChineseStandard.net ?
