GB 25285.1-2010 Explosive atmospheres—Explosion prevention and protection—Part 1:Basic concepts and methodology

Scope

This section specifies methods for identifying and assessing hazardous situations that may lead to explosions, as well as design and structural measures adapted to safety requirements, achieved through the following aspects:
——Hazard identification;
——Hazard assessment;
——Eliminating hazards or minimizing their impact;
——Using information.
The safety of equipment, protective systems, and components can be achieved by eliminating hazards and/or limiting them, namely by taking the following measures:
a) Achieving this directly through design, without the need for safety protection devices;
b) Achieving this through the use of safety protection devices;
c) Achieving this by communicating information to users via communication devices, if necessary;
d) Taking other additional preventive measures.
The explosion-proof measures corresponding to a) (prevention) and those corresponding to b) (protection) are addressed in Chapter 6 of this section. The explosion-proof measures corresponding to c) are addressed in Chapter 7 of this section. The explosion-proof measures corresponding to d) are not addressed in this section, but are covered in Chapter 5 of GB/T 15706.2-2007.
The preventive and protective measures specified in this section do not provide the required level of safety unless the equipment, protective systems, and components operate within their intended range of use and are installed and maintained in accordance with the corresponding operating procedures or requirements.
This section specifies general design and manufacturing methods to assist designers and manufacturers in achieving explosion-proof safety when designing equipment, protective systems, and components.
This section applies to equipment, protective systems, and components intended for use in explosive atmospheres under atmospheric conditions. These atmospheres may be caused by flammable substances handled, used, or released
