1.0.1 This code is drawn up for the sake of implementing the policy for electrical installation design of explosive and fire hazardous atmospheres with stress on prevention so as to guarantee the safety of people and property, to take preventive measures to suit local conditions, and to make the design with advanced technique, economy and rationality, and safety and suitability.
1.0.2 This code is suitable for the electrical design of new, extension and renovation engineering projects which emerge or likely emerge explosive and fire hazardous atmospheres in the procedure of production, processing, treatment, transferring or storing.
This code is not suitable for the following atmospheres:
1. Under mine shaft;
2. In the atmosphere where gunpowder, explosives and primer are manufactured, applied and stored;
3. In electrical installation area of electrolysis, electroplating, etc. where electric energy is used for production and is directly related to the production technological process;
4. In storage battery room;
5. In the atmosphere where strong oxidant as well as material self-ignitable without ignition from external fire source;
6. In communication and transport vehicles on land, water and in air, and off - shore platform for oil well.
1.0.3 The electrical design for explosive and fire hazardous atmospheres, besides shall conform to the stipulation of this code, shall further conform to the stipulations of relevant national standards and codes.
