Slip TANKS in Canada a Reminder before the Ticket!

Spring is always a time when you can buy on line on a variety of sites Slip Tanks and before you fork out monies for that cheap unit you may want to remember your Transport Canada T.D.G. training regarding these items.

Transportation of Dangerous Goods (TDG) Regulations, states that most containers commonly referred to as “slip tanks” or “tidy tanks” must be certified by the manufacturer. This means that it must be manufactured to the Canadian General Standards Board Standard CAN/CGSB 43.146. There are certain times when a certified tank is NOT required. For example:

SLIP TANK FOR DIESEL ONLY (450 L limit)

A tank with a capacity of 450 L or less does not need to comply with any standard if it only contains diesel. You will find this exemption under the TDG Regulations.

Please note: You may NOT use this exemption to transport gasoline.

Also, when using this exemption:

  • you do NOT need a shipping document ;
  • the tank or the truck does NOT need labels or placards ; and
  • you do NOT need to be trained .

SLIP TANK FOR GASOLINE AND DIESEL (2000 L limit)

You will find another exemption for slip tanks under regulations. This exemption states that when you are transporting gasoline or diesel:

  • you do NOT need a shipping document ;
  • you do NOT need to display a UN number on the tank (Note: A label or placard must still be displayed); and
  • you do NOT need to be trained .

You are NOT exempt from (Means of containment). This means that:

  • the slip tank (i.e., means of containment) must be certified by the manufacturer;
  • the tank is subject to periodic inspections by a facility registered with Transport Canada; and
  • the tank(s) is/are limited to a total maximum combined capacity of 2000 L.

How much diesel / gasoline may I carry in a slip tank?

Answer: The answer depends on whether you plan on using an exemption under the TDG Regulations.

If you do not want to use any of these exemptions, there is no limit. This means that:

  • you will need a shipping document for the dangerous good in the tank;
  • you must be trained and hold a valid training certificate as set out in f the TDG Regulations;
  • the tank must be certified by the manufacturer. This means that it must be manufactured and maintained in accordance with the Canadian General Standards Board Standard CAN/CGSB 43.146 or CSA B620; and
  • the tank is subject to periodic inspections by a facility registered with Transport Canada.

Do I need double walled slip tanks to carry diesel / gasoline?

No. There are no Transport Canada requirements that currently exist for using “double walled” tanks for transporting products such as diesel fuel, fuel oil or gasoline

Even though it may seem safer to use a double walled tank to contain leaks, the inter-wall space of double-walled tanks might collect contaminants and moisture that can accelerate corrosion. Also, these tanks make it harder for inspectors to detect corrosion between the tank walls. Conducting effective and adequate periodic inspection of transport tanks is key to preventing leaks and other failures. Since double-walled tanks are more likely to corrode and are more difficult to inspect, they may be less reliable over the long term unless inspectors take sophisticated measures during periodic inspections.
