WebNow lets come to point F on the flammability diagram. Point F is where we have oxygen around 4 to 5% and the hydrocarbon content is around 11% by volume inside the cargo tank. This is the case normally when the cargo has been discharged, but the hydrocarbon content is still there inside the tank. WebThis is halfway between 17% (below which breathing for unacclimatised people becomes difficult) and 25% (above which many organic compounds are highly flammable). The element and its compounds make up 49.2% by mass of the Earth’s crust, and about two-thirds of the human body.
