Are floating roof storage tanks safe?Are floating roof storage tanks safe?Floating roof storage tanks are inherently safer than fixed roof tanks as they essentially eliminate the creation of a vapor space in the tank above the combustible liquid. Floating roof storage tanks have their roofs actually resting on the stored liquid and rise and fall as the inventory level changes.Floating Roof Tanks FeedbackAPI 650H standard Internal Floating Roof Tank IFR
