Propane Bulk Plant
A storage site where propane is received in bulk, kept in pressure vessels and sent out in delivery trucks and cylinders.
What it does
Propane is odourless, so ethyl mercaptan is added and the odour level must be confirmed; a Canadian field method exists to test it. In Canada storage and handling follow CSA B149.2.
