Make sure there are no electrical conduits or similar leading down through the floor to another space that is at a lower elevation. Stuff happens despite what others may claim. It is not unlike, "there is nothing to burn”. I’ve seen an installation, not a diesel fire pump but an emergency power generator, where a failure in the day tank resulted in the above ground diesel tanks siphoning out fuel at the generator which then traveled via the electrical raceways down to the basement electrical room at the adjacent building. Include planning for how the owner would prefer to handle that spill. The facility people often have the better perspective. They also have a say in the contract process.
