A Guide to Home Heating Oil Tanks
7
If you have an indoor tank, place it in the lowest level of the building, such as a crawlspace or
basement. If you locate it elsewhere, (inside an attached garage that is not the lowest floor),
ensure that it is inside an extra container at least the same size as the tank, or on a drip pan
fitted with an alarm. If this isn’t possible, use anti-siphon valves . Regardless, an extra system of
containment is a good idea.
Your indoor tank should be inspected regularly for signs of leakage, oil stains and odours in the
basement. Vent and fill pipes must terminate outdoors to prevent fuel leaks or vapour intrusion
into the living space.
Oil vapours are not only dangerous from a combustible viewpoint but are a potential health
hazard to occupants and can cause headaches, nausea, dehydration, and dizziness.

Notice the fill and vent pipes terminate outdoors.
Vehicle bumpers could contact this unprotected
tank. It is likely leaning due to a bumper having
pressed against it.
Protect the tank from vehicle impact with posts if
no other location is possible.
