This pail kit keeps the contents protected in a waterproof container. The grey sorbent pad and sock are universal, which means they will absorb up to 35 litres of petroleum products or chemicals. This kit is not for marine oil spills, since the universal style pads will soak up water and sink. The pail kit is ideal for in-plant use for hydraulic equipment such as forklifts working in a shop or for waste disposal or service trucks.
