    • REGULATORY REQUIREMENTS Companies and persons working with propane are regulated to ensure the safe handling, transferring, and use of propane . Regulatory requirements for training, certification, sale,installation and use of propane may appear in Ontario Technical Standards and Safety Authority Regulation.Contravention of the Regulations may result in tickets, penalties, or litigation by the authority having jurisdiction.Regulations developed by Industry and Government reflect the proper and safe method of completing tasks To properly handle transfer propane you need to know thehazards of the product, the equipment used to store and transfer propane and proper procedures to follow.
    • CHECKING ANG TESTINGTesting Requirements for Tanks. Initial Testing. All tanks, whether shop built or field erected, shall be tested before theyare placed in service in accordance with the applicable requirements of the code under whichthey were built.An approved listing mark on a tank shall be considered to be evidence of compliancewith this requirement. Tanks not marked in accordance with this subsection shall be tested beforethey are placed in service in accordance with good engineering principles. Tightness Testing. In addition to the tests called for in 4.4.1, all tanks and connectionsshall be tested for tightness after installation and before being placed in service accordancewith 2.4.2.2 and 2.4.2.3, as applicable. Except for underground tanks, this test shall be made atoperating pressure with air, inert gas, or water. Air pressure shall not be used to test tanks thatcontain flammable or combustible liquids or vapors. Single wall underground tanks and piping, before being covered, enclosed, or placed inuse, shall be tested for tightness either hydrostatically or with air pressure at not less than 3 psigand not more than 5 psig.Underground secondary containment tanks and horizontal aboveground secondarycontainment tanks shall have the primary (inner) tank tested for tightness either hydrostaticallyor with air pressure at not less than 3 psig and not more than 5 psig. Additional Testing. Tanks that have been relocated, structurally damaged, repaired, orare suspected of leaking shall be tested in a manner acceptable to the authority having thejurisdiction.
    • DURING PERFORMING THE TASK Major Modification Activities :• Repairing, removing or replacing any part of the tank.• Replacing or repairing equipment when excavation is required.• Adding ancillary equipment.• Installation, repair or replacement of interior (internal) tank lining or coating.• Installation of corrosion protection systems or anodes on cathodic sacrificial and impressed current systems.
    •  Minor Modification Activities :• Staking and placing of concrete forms over the tank field.• Replacement, repair or removal of aboveground piping associated with the system (excluding dispenser components).• Replacement, repair or removal of the check valve in a suction system.• Replacement or removal of leak detector/pump-manifold (packer) assembly.• Replacement, removal or disconnection of flexible piping connectors.• Replacement, removal or disconnection of break-away (shear) valves.• Replacement or removal of primary piping through extraction from the secondary piping or double walled piping systems or double wall piping from a tertiary conduit when accessible from aboveground or through man ways (not involving an excavation).• Installation or replacement of anode bags or spike anodes to flexible piping connectors.• Installation or replacement of isolation boots.• Installation of a line leak detector.• Changing the type of line leak detector, such as, mechanical to electronic.• Installation, repair or replacement of overfill prevention devices.• Installation, repair or replacement of spill containment devices.• Initial installation or complete replacement of an automatic tank gauging system.• Replacement of a complete dispensing unit.
    • Maintenance Each tank shall be inspected and maintained to ensure compliance with the requirements of this code. Testing requirements for tanks shall be in accordance with Section 4.4 Each tank shall be maintained liquid tight. Each tank that is leaking shall be emptied of liquid or repaired in a manner acceptable to the authority having jurisdiction. Tanks that have been structurally damaged, have been repaired or reconstructed, or are suspected of leaking shall be tested in accordance with 4.4.1 or in a manner acceptable to the authority having jurisdiction. Tanks and all tank appurtenances, including normal vents and emergency vents and related devices, shall be properly maintained to ensure that they function as intended. Openings for gauging on tanks storing Class I liquids shall be provided with a vapor tight cap or cover. Such covers shall be closed when not gauging.
    • CONCLUSION Underground tank present unique challenges not experienced with thoseinstalled aboveground. It is important to make sure this is given careful consideration in the installation and inspection of underground systems to minimize problems and provide satisfactory service.
