The floor is required to drain. If that is accomplished with a floor drain it requires an oil separator. That is what the code says unless it meets the exception. The way it is written I would say it is up to you to make the determination of whether or not the slope alone is sufficient. If I had to make this call I would want to know the answers to these questions:

1. How big is the hangar?

2. How many aircraft are going to be in the hangar?

3. Will there be any fueling in the hangar?

4. Will there be any major mechanical work in the hangar?

5. Is there water plumbed to the hangar?

Are floor drains required in an airport hangar is it meets the floor sloping requirements? I have read 412.4.3 and it does not say they are required and states "if provided" in the commentary. Thanks
