Fossil fuels are essential to heat our homes and operate our vehicles. During the winter it takes many gallons of heating fuel to keep your home warm. Construction companies and farmers use thousands of gallons of fuel in the vehicles that are necessary to get the job done. Fuel storage tank fuel safety at home or on the job prevents catastrophic lose due to fire or other serious disaster.

Rural Tanks

The National Fire Protection Association (NFPA) standard 395 applies to fuel tanks on farms or other rural locations holding less than 1100 gallons. This standard does not apply to tanks used to store home heating fuel, or to store fuel for stationary engines. Above ground fuel storage tanks must be constructed of steel. Tanks with a storage capacity of 561 to 1100 gallons must be constructed of twelve gauge metal. The fill opening must be separate from the vent valve. The vent valve must be located so fuel vapours escaping the tank do not come in contact with heat sources. The location of a farm fuel storage tank is very important to fire safety issues. If your above ground tank is installed closer than 40 feet to a building made of combustible material it must be erected according to NFPA standards 30 and 30A.

Commercial Tanks

There are several simply safety regulations that make operations around commercial fuelling stations much safer. There must be signs designating the area around fuelling operations and fuel storage tanks as a no-smoking area. This area must extend out 20 feet from the fuel storage tank or fuel dispenser. Commercial fuelling stations must also require the vehicle operator to turn off their engine, and members of the public must be at least 16 years old to dispense fuel. The applicable NFPA standard is 30A, Fuel storage tanks in commercial use must be built according to standards defined in NFPA 30 with a sign or label indicating compliance with the standard.

Underground Tanks

Underground fuel storage tanks should not be installed closer than three feet to a basement wall or property line. There must be a one foot distance maintained between underground fuel tanks, and storage tanks must be constructed with corrosion resistant materials to protect against leakage. There standards are described in NFPA 30. Inspection requirements for underground fuel storage tanks include a tank pressure test, pressure test of system piping to 150 per cent of anticipated operational pressure, and a soap inspections of all fittings and tank seams in accordance with NFPA 30.2-8. A soap inspection involves spreading a soapy mixture on the fitting of a pressurised pipe and looking for the soap to bubble-up indicating a leak.
