Vessel for collecting and extinguishing combustible liquids

A vessel for collecting liquid, comprising a plurality of hollow bodies each having a length dimension:

• said hollow bodies being arranged side-by-side parallel to their length dimension and being secured to one another to form an assembly;
• each said hollow body defining an enclosed inner chamber for accommodating the liquid;
• the chambers of the respective hollow bodies being separated from one another;
• each hollow body having an outer upper surface inclined downwardly in a direction transverse to said length dimension;
• the inclined upper surfaces of any two adjoining hollow bodies together form a trough extending parallel to said length dimension;
• each trough having a bottom and drainage openings at said bottom for providing passage of the liquid from each trough into said inner chambers underneath the respective troughs;
• each hollow body further having an external apical portion;
• and further comprising a vent pipe secured to each hollow body in said apical portion thereof and extending vertically upwardly from said apical portion;
• each vent pipe defining a vent opening maintaining communication between the respective inner chamber and the ambient atmosphere.
