1. The prop must be a comparable size to a 1,000-gallon liquid propane tank with nominal dimensions approximately 16 feet long and 41 inches in diameter. The tank prop must have the appearance of an actual liquid propane tank. 2. The prop must have a functional dome cover containing simulated components that include a liquid level gauge, functional service valve, propane regulator, propane fill valve, and vapor return line. The tank must also have a simulated liquid withdrawal valve and relief valve located on the top of the tank. Higher preference will be given to props that most closely replicate a real liquid propane tank and component assembly. a. A functional service valve is requested and expected to experience normal wear from usage. It is preferred that this valve is replaceable as needed for repair. 3. The prop must be accessible for fire attack and vapor control exercises from all sides without substantial obstructions from components.
