You may ask yourself why and when do I need a Spill Kit?
If you have a warehouse or a yard that stores oil & fuel, dangerous goods, you have a forklift and trucks that come into and out of your site, then you need a spill kit.
See the above Spill Kit Chart as to which spill kit you may need? General Purpose (GP), Oil & Fuel or Hazchem.
The two essential differences between any spill kit is what volume of liquid it can absorb, defined in litres and what sort of liquid the spill kit can effectively absorb and safely contain.
