Beschreibung
Zusammenfassung:	A temporary hood for capturing vapors exiting from a material storage compartment of a vessel when the compartment is opened includes a base frame that extends around an opening to the compartment and is releasably secured to the vessel. An upper framework is releasably coupled to the base frame and extends upwardly from the vessel around the opening. A plurality of panels are releasably engageable with the upper framework and form an enclosure around the opening. At least one vapor discharge outlet fluidly communicates with the material storage compartment and a vacuum pump to allow the capture of vapors exiting from the opening when the cover is opened and the temporary hood is engaged with the vessel.
