The Technical Standards and Safety Authority has posted a Director's Order on propane storage tanks designed for 200 pounds per square inch gauge (PSIG).
Pursuant to section 14(2) of the Technical Standards and Safety Act, 2000, the Director orders any tank that has a maximum allowable working pressure (MAWP) of less than 250 psig to be taken out of service. This requirement is effective as of October 1, 2025.
While all new installations require 250 psig tanks, there are existing propane storage tanks designed for 200 psig installed and in service. With the aging of these tanks, it is unsafe to allow their continued operation. Given the limited number of propane storage tanks designed for 200 psig installed in the field, most provinces have agreed that 200 psig propane storage tanks should be taken out of circulation as they are not in accordance with the code.
Please read the Director's Order for details.
