Foreword

GB 11666 "fertilizer manufacturing Health protection" is divided into four parts.

--- Part 1. nitrogen fertilizer manufacturing;

--- Part 2. phosphate fertilizer manufacturing;

--- Part 3. potash industry;

This section GB Part of 211,666.

This section 4.2 to 4.4 are recommended, the rest are mandatory.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB 11664-1989 "calcium and magnesium phosphate fertilizer plants Health protection standards" and GB 11665-1989 "ordinary superphosphate Plant health protection from the standards. " Compared with GB 11664-1989, GB 11665-1989 main technical changes are as follows.

--- Adjust the standard name, and according to GB/T 1.1-2009 standard structure adjustment;

--- Amendments to the definition of health protection distance, increasing the sensitive area of complex terrain two terms and definitions;

--- Revised the Health protection zone standard limits, increasing the scale of production sub-file;

--- Increased requirements for greening.
