Foreword

Subclauses 5.2.2, 5.2.6 and 8.3.3 of this standard are recommended; the rest is mandatory.

This standard was prepared on the basis of the practical experience of aluminium and magnesium powder processing in China, with reference to the US National Fire Protection Association standards NFPA 480 Storage, handling and processing of magnesium solids and powders (1998 edition) and NFPA 651 Machining and finishing of aluminum and the production and handling of aluminum powders (1998 edition).

This standard replaces GB 17269-1998 Safety regulation for the prevention and protection of dust explosion in manufacturing powder of aluminum and/or magnesium.

The main changes of this standard compared with GB 17269-1998 are as follows:

- the structure of some clauses and subclauses has been adjusted (Clauses 6, 7, 8, 9 and 10 of the 1998 edition correspond respectively to Clauses 7, 8, 10, 9 and 6 of this edition);

- some provisions have been added on the basis of production practice in China (7.3.7 of this edition);

- some provisions have been deleted on the basis of NFPA 480 (1998 edition) and NFPA 651 (1998 edition) (6.3.4 of the 1998 edition).

This standard was proposed by the State Administration of Work Safety.

This standard is under the jurisdiction of the National Technical Committee for Standardization of Dust Explosion Prevention and Protection.

Drafting organizations of this standard: Wuhan Research Institute of Safety and Environmental Protection, Northeast Light Metal Powder Company, Beijing Xinlihua Magnesium Powder Research Institute.

Main drafters of this standard: Zhou Hao, Yu Yongfang, Deng Xufan, Wu Changhai, Wang Hongjin, Li Xiaofei, Cai An.
