What You'll Learn
Old fuel oil tanks can corrode and leak
Old fuel oil tanks can pose a serious risk to both your home and the environment. While explosions are not an issue, and heating oil will not burn unless heated and turned to vapour, there are still several dangers associated with old fuel oil tanks. Firstly, if your tank is 15 years old or older, it is at a higher risk of corrosion and leaking. Tanks can corrode from the inside out, which may initially present as a minor hole or leak but is indicative of a larger internal problem. Over time, factors like corrosion or damage can cause a tank to wear out, compromising the walls and allowing oil to contaminate the soil and groundwater. This can have a negative impact on the environment, including the health and safety of people. For example, a slow leak from an underground tank can spread from the soil into groundwater and then into surface water, impacting not just your home but those around you.
Leaking oil can also cause damage to your home heating system. If you notice any signs of leaks around your tank, filter, fuel-delivery line, valves, piping, or fittings, or if your tank has been patched to temporarily conceal a leak, you should contact your oil supplier immediately. Old fuel-fill lines that are no longer connected to the tank can also cause a massive oil leak if they are inadvertently filled.
Furthermore, heating oil is a moderately toxic substance that can be harmful to human health when inhaled. Short-term exposure to heating oil fumes can cause headaches, nausea, increased blood pressure, dizziness, difficulty concentrating, and irritation to the eyes, nose, and throat. Long-term exposure can lead to more serious health problems, such as liver or kidney damage. Therefore, it is important to have your heating oil tank regularly inspected by a professional to detect any signs of corrosion or leakage early on. This can help prevent more costly and challenging problems down the line.
If you suspect a leak or spill, it is important to take immediate safety measures, including contacting your fuel supplier. Small spills can be cleaned up by wearing rubber gloves and old clothes that can be disposed of afterward, while larger spills will require professional cleanup. The cost of cleaning up an oil spill can be extremely high, often running into hundreds of thousands of dollars, and can put homeowners at risk of bankruptcy. Therefore, it is crucial to take proactive measures to prevent leaks and spills from occurring in the first place.

Leaks can cause environmental damage
Heating oil tanks can be located underground, in basements, or above ground outside of a house. While heating oil is generally safe when stored and used appropriately, leaks and spills can occur and cause environmental damage. A slow leak from an underground oil tank can spread from the soil into groundwater and then into surface water, impacting not just the homeowner but also neighbouring properties. For example, groundwater may become unusable for irrigation, affecting nearby farmers. A leak that contaminates surface water can also harm wildlife and impact public health.
Oil leaks can occur for several reasons, such as when a storage tank develops a leak due to corrosion, or when it is damaged, overfilled, or improperly decommissioned. Old fuel-fill lines that are no longer connected to the tank can also cause a massive oil leak if they are inadvertently filled. Tanks can corrode from the inside out, presenting as a minor hole or leak but indicating a larger internal problem. Over time, factors like corrosion or damage can cause tanks to wear out, allowing oil to contaminate the soil and groundwater.
The environmental impact of oil leaks is significant. Heating oil contains toxic chemicals such as kerosene, range oil, and jet fuel. If pipes connected to the heating oil tank run through the house, a tank leak can produce vapours that are harmful to human health when inhaled. Short-term exposure to heating oil fumes can cause headaches, dizziness, and nausea, while long-term exposure can lead to more severe issues like liver or kidney damage.
To prevent leaks and minimise environmental damage, regular inspections of heating equipment and oil tanks are crucial. Homeowners should also be aware of the signs of a leaking tank, such as dying vegetation surrounding an outdoor tank or the presence of old, rusty, loose, or wobbly tank components. If a leak is detected, immediate safety measures should be taken, including contacting the fuel supplier and, in the case of larger spills, professional cleanup services.
