Excellent way of catching drips when you are pumping out of 205ltr/45gal drums to prevent liquids collecting on the surface of the drums. The yellow colour identifies these pads are suitable for chemical liquids. Highly absorbent these pads should be used whenever the drum is in use to prevent any spills from spreading.
Also available as general purpose absorbent drum toppers if not using chemicals.
As with all absorbents these should be disposed of carefully in a hazardous waste bag
