Tank Cleaning and Waste Management

At Rafibra we are experts in tank cleaning for diesel, petrol, Jet A1 and chemical products such as acetone, alcohol or paints.

We carry out the cleaning in the most effective and safe way, once the tank has been degassed and controlling that the gases of the atmosphere inside the tank are below 1% I.E.L. at all times.

Once this part is controlled, we start with the extraction of the muds from the bottom of the tank, cleaning the walls with high pressure water and disinfectants designed and created by our chemists, brushing and drying the tank.

The liquids resulting from the cleaning will be packaged in suitable containers for subsequent transfer to the toxic and hazardous waste management plant. In this respect, Rafibra is the manager-transporter of the hydrocarbon sedimentation mud and other hydrocarbon waste. Both in this operation and after the suction of the remains of fuel that remain in the interior of the deposit, the decrease of the explosivity index will be verified.

All ventilation equipment must be connected to earth, together with the tank structure.

In any case will use the oxygen for ventilation.


Access and stay inside the tank will not be allowed until the tank will have less of 1% of the I.E.L

The workers that access to the interior of the tank will be provide with the following equipment:

The entry and stay of persons inside the tank, under the above conditions, will be always subject to external security, ready for evacuation.

Access to the interior will be with non-sparking equipment (aluminium ladder, with rubber stoppers, etc.) and in such a way that rapid evacuation is always possible.

Lights equipment will be explosion-proof and with a power supply no more of 24V.

Will take special care when removing muds, as this will again produce an explosive atmosphere. Will be maintain the precautions described above and, if necessary, will repeat the degass procedure.
