GB 50193-1993(2010) 二氧化碳滅火系統設計規范 (英文版)

1.0.1 This standard is formulated with a view to reasonably designing carbon dioxide extinguishing system, reducing fire hazards, and protecting and the safety of people and property.

1.0.2 This standard is applicable to the designs of carbon dioxide extinguishing systems arranged in new, rebuild and extended engineering and storage systems. 

1.0.3 The design of carbon dioxide extinguishing system shall actively adopt new technique, process and equipment, and be of safety and application, state-of-the-art, and economic feasibility.

1.0.4 Carbon dioxide extinguishing systems may be used for extinguishing the following fires:

1.0.4.1 Gas fire, which the gad source can be cutted off before fire extinction 

1.0.4.2 Liquid fire or meltable solid (like paraffin and asphalt) fire

1.0.4.3 Solid surface fire and solid deepseated fire (like cotton wool, fabric and paper)

1.0.4.4 Electric fire 

1.0.5 Carbon dioxide extinguishing systems must not be used for extinguishing the following fires:

1.0.5.1 Fires of chemicals (like nitrocellulose and blasting powder) containing oxidants

1.0.5.2 Fires of active metals like kalium, sodium, magnesium, titanium and zirconium

1.0.5.3 Fires of metal hydrides like potassium hydride and sodium hydride

1.0.5A Total flooding carbon dioxide extinguishing system shall not be applied at the places where staffs stay often.

1.0.6 The design of carbon dioxide extinguishing system, besides the requirements of this standard, shall also meet the requirements of the current related national standards.
