How should inside oil tanks be gauged according to regulations?

Inside oil tanks should not be gauged as a standard practice according to regulations. The primary concern with gauging inside oil tanks involves safety and environmental risks. Accessing the inside of a tank requires proper safety measures, as it can expose individuals to hazardous vapors or potential leaks. Regulations are designed to mitigate risks associated with such activities.

Alternative methods, like using electronic sensors or measuring sticks, might provide safer and regulated approaches to monitoring levels from the outside of the tank without needing to enter. Visual inspections also do not suffice for accurately gauging the contents of an oil tank, as they may not provide the detailed information needed to ensure safe levels and compliance with standards. Thus, regulations prioritize safety and discourage practices that could lead to unsafe conditions.
