(1) The separation distances required by AS 2187.1 must be maintained between any of the following on the premises where explosives are likely to be present and each ammonium nitrate store:
(a) magazines;
(c) process buildings.
Note In applying AS 2187.1:
• reg 16 must be used to work out the collective hazard division of explosives that are stored together instead of the approach set out in the standard itself
• a reference to NEQ of an explosive is taken to be a reference to the gross quantity of the explosive (including packaging)—see reg 21.
(2) For working out the separation distances required by the standard between a central mixing point and an ammonium nitrate store, a reference to the quantity of the explosives is taken to be a reference to the greater of the following:
(a) the maximum quantity of explosives that can be present at the central mixing point;
(b) half the quantity of ammonium nitrate that can be present at the central mixing point.
