peer agreement (net): +5floating roof Explanation: Some storage tanks need a floating roof in addition to or in lieu of the fixed roof and structure. This floating roof rises and falls with the liquid level inside the tank, thereby decreasing the vapor space above the liquid level. Floating roofs are considered a safety requirement as well as a pollution prevention measure for many industries including petroleum refining. Reference: http://en.wikipedia.org/wiki/Storage_tank |
