Overview of the storage tank regulations - Canada.ca

The regulations apply to storage tank systems that ():.are comprised of tanks that have a capacity of more than 230 litres and are designed to be installed in a fixed location; contain petroleum products such as used oil,home heating oil,jet fuel,diesel and gasoline,or allied petroleum products such as biodiesel,general-purpose thinners for lacquers,isopropanol,uninhibited ethylene Oil Storage Tank Leak Testing Methods ProceduresOil tank ultrasound oil tank leak risk screening program (photo above) is offered by some oil companies who scan the bottom section of above ground oil tanks to measure the thickness of the tank steel.Tanks that pass an ultrasound screening test may be insured against future leakage.Lessons to prevent deaths during hot work in,around tanksA contract welder was killed while welding on a catwalk located over a 9,300-gallon waste oil storage tank at the Philip Services Corporation (PSC).Following an investigation,the Honolulu Fire Department (HFD) concluded that,during the welding,sparks dropped in and around the vent area of the tank.
