Bulk Oil Ventilation

[lojack1]

I have a bulk oil storage room that serves the service shop for a dealership in Florida that I need to ventilate. The room is 20 x 10 x 17. What cfm fan do I need and can I ventilate this room with air from the service shop or do I have to ventilate with 100% outdoor air. The service shop is well ventilated with specialized tailpipe exhaust system and carbon monoxide detection system.

I would take outside air, since the service shop is allready ventilated and possible under negative presssure.

If you take more air from the service shop you need to supply more or get more air to the service shop as well. This makes me ask how is the air supplied to the service shop?

Just my 1 cent contribution.
