Nitro-foam inerting is an innovative method developed for the inerting of fuel tanks in lieu of water filling. As petrol tanks must be made safe prior to opening them up, this method was designed to positively vent explosive vapours from the tanks in a controlled and safe manner.

This type of inerting for underground petroleum tanks can be advantageous when rendering tanks safe for:

  • Temporary inerting prior to cleaning and gas-freeing
  • Breaking down manhole chambers and exposure of tank tops
  • Removal of manlids and associated pipework
  • This method is cheaper than water filling and subsequent water disposal by tanker. The nitrogen filled bubbles force out fuel vapour and then dissolve away to virtually nothing. It also saves time, with only one operation instead of two, and avoids time delays while waiting for tankers.

    Building on our 20-plus years of experience using Nitro-foam, we have developed and improved our own self contained inerter, which keeps the foam consistent, regardless of local mixing water quality. The main part to the equipment does not even need unloading from our vehicle to operate.
