The new community regulations, concerning safety and prevention at work, provide for the deployment of first aid kits to stem and absorb any leaks of dangerous liquids. The kit is contained inside UN approved polyethylene drums for solids with total opening and perfectly stackable and palletizable. The drums are easy to move thanks to the two handles or grooves placed on the sides of the drums. The galvanized steel locking carabiner can be sealed to make the contents inviolable. These drums are made of high density and high molecular weight polyethylene, with the addition of an anti UV additive.
