To prevent undetected oil leaks, conduit must penetrate the cement surface how many inches above grade?

The requirement for conduit to penetrate the cement surface by two inches above grade is designed to ensure that any potential leaks or drips from the conduit are effectively contained and do not seep into the surrounding areas, which could lead to environmental contamination or property damage.

This height provides a sufficient barrier, allowing any leaking oil to flow away from sensitive surfaces and accumulate instead in areas where it can be detected and managed appropriately. Ensuring that the conduit is elevated above grade also assists in preventing any buildup from moisture or debris that could compromise the integrity of the conduit itself. Ultimately, this regulation helps uphold safety standards and environmental protection measures vital in oil fuel management.
