Description of Compilation The “Illustrations of Safety Protection on Sites of CSCEC’s Overseas Projects” (Illustrations) is compiled in accordance with relevant laws, regulations, standards and specifications of China as well as related stipulations of countries and regions where CSCEC has been carrying out business operations, combining with China’s construction safety management system and actual situations on site The compilation is done to implement CSCEC’s safety concept of “Life First and Safety First” and realize normalization and standardization of safety facilities on construction sites I Principles and Requirements of Compilation The compilation is done complying with laws, regulations and standards of the state, based on which, we strive to make it simple, practical, easily kept, well circulated and instrumentalized The compilation, taking full account of geographical differences, has classified the Illustrations into such three parts as Basic Protection, Standard Protection and Upgraded Protection The Basic Protection is the bottom line, followed by the Standard Protection to be popularized and the Upgraded Protection to be recommended The Upgraded Protection is the relevant addition of the Standard Protection The standard or standards of the host countries, if higher than the Illustrations, shall be applied The materials included in the Illustrations for undertaking protections shall have to meet the specifications in terms of rigidity, thickness and side impacting force The Illustrations includes the most basic site protections other than those uncovered protections which shall be done in line with “Illustrated Standards for Safety Protection on Construction Sites of CSCEC’s Projects” (2014 edition) The Illustrations shall be implemented from the date of its issuance II Basis of Compilation Law of the People’s Republic of China on Safety Production Safety Management Measures for the Safety Management of Large and
