APPROVAL OF EQUIPMENT FOR AMMONIA REFRIGERATION
Some ammonia refrigeration rooms are classified as non hazardous. These may
be in ice rinks or large food processing plants etc.
Memo 18-24-96 gives some advice, but it is not clear that some ammonia rooms
are hazardous and some are not.
If MCCR classifies an ammonia room as a "Class T Machinery Room" then the
room is non-hazardous.
If MCCR classifies it as a "Machinery Room", then it is hazardous location,
Class 1 Division 2.
This follows the CSA specification B52, Mechanical Refrigeration Code used
by the MCCR for Pressure Vessels.
