Our authorisations
- Albo Gestori Ambientali no. MI03807 – category 9 (site remediation)
- Categories 4 and 5 for the transport of non-hazardous and hazardous waste
- Staff qualified for work in confined spaces
Work in confined spaces: entering a tank is dangerous and must only be done by qualified staff with specialist equipment. Don't try it yourself: call us.
How we work, step by step
- Site inspectionWe check the site or the tank: type of product it holds, volume, access and whether there have been any leaks.
- EmptyingWe pump out the remaining product and sediment with the vacuum tanker and handle them as waste.
- Internal washing and cleaningWe wash the tank with specialist equipment, following the procedures for confined spaces.
- Gas-free certificateA qualified chemist measures the gases and issues a certificate stating that the tank poses no risk of explosion.
- Removal or filling with inert materialWe remove the tank or, if that is not possible, fill it with inert material and leave it safely where it is.
- Disposal and checksWe dispose of residues and scrap with a waste transfer form. If the soil turns out to be contaminated, we start the notifications and analyses required for remediation.
The laws to comply with
- Legislative Decree 152/2006 (Italian Environmental Code), Part IV Title V
- Remediation of contaminated sites: if an event occurs that could contaminate the soil, the authorities must be notified and the site characterised (art. 242).
- Legislative Decree 152/2006 (Italian Environmental Code), art. 192
- Dumping waste is prohibited: the person responsible and, in some cases, the owner must remove it and restore the area.
- Legislative Decree 81/2008 and Presidential Decree (D.P.R.) 177/2011
- Tanks are confined spaces: work inside them may only be done by a qualified company.
- D.P.R. 151/2011
- Fire prevention: for diesel stores subject to Fire Brigade inspection, decommissioning must be notified.
- Albo Gestori Ambientali, categories 5 and 9
- Transport of hazardous waste and site remediation: we are registered in both.

FAQ
Do I have to remove my old diesel tank?
Not always: often it is enough to empty it, clean it and make it inert. After the site inspection we tell you the simplest and cheapest solution for your case.
What is a gas-free certificate?
It is the document certifying that the tank no longer contains dangerous vapours. You need it to decommission the tank or to work on it safely.
