The Carbery Plastics survey analysed compliance with OFTEC storage tank installation requirements at 150 domestic heating oil storage installations across Ireland.
In the Republic of Ireland, environmental protection was the biggest issue with 72% of surveyed tanks incorrectly specified as single skin tanks at installations where a bunded tank was required.
In Northern Ireland, fire protection was the biggest issue, with 60% of tanks non-compliant with fire safety requirements.
Carbery’s John Switzer said: “When installed in accordance with OFTEC requirements, modern plastic oil tanks can provide many years of reliable, dependable service. However failure to install a storage tank correctly can cause irreparable damage and significantly reduce operational life. Non-compliance with installation instructions and statutory requirements means that some technicians are exposing themselves and their customers to unwelcome and wholly unnecessary risk and liability.”
