The French decree of November 19, 2009 relative to general prescriptions applicable to classified installations declared under paragraph number 1136 (use and storage of ammonia) replaces the previous decree of February 23, 1998, which was rescinded as of April 24, 2010. This new decree, applicable since April 2010, should facilitate the implantation of ammonia refrigeration installations in France thanks to the reduction of their minimal distance from property limits from 50 to 10-15 metres, provided that certain security measures are strengthened, such as protection against fires and leak detection.
