What is a sign that a propane container may need further inspection?

The presence of oil around fittings on a propane container is a significant indicator that further inspection is needed. When oil appears around the fittings, it can suggest that there may be a leak or a failure in the connection points, which poses a serious safety risk. Gas and oil do not mix; hence, the presence of oil may indicate that gas is escaping, creating a hazardous situation that needs immediate attention.

In contrast, while visible scratches on the container may indicate wear, they don't necessarily mean that the container is leaking or unsafe. Normal weather exposure is expected for propane containers and does not by itself warrant concern unless there are signs of corrosion or damage. Rust on the outside could indicate deterioration, but it is the combination of rust and other visible issues that typically signals a need for deeper evaluation. Therefore, the presence of oil specifically calls for inspection to ensure that the fittings are secure and that there are no dangerous leaks.
