However, it is important to note that when diesel fuel is blended with ethanol (e-diesel) to reduce emissions, blended diesel fuel has a low flash point of about 68F (20C). Mixed fuel is therefore considered a flammable liquid that requires management of the associated fire and explosion risks. For simplicity, only conventional diesel fuel is considered in this article. But gasoline can be dangerous if not handled or stored properly. Gasoline should only be used for its intended purpose – as fuel – and stored only when absolutely necessary. It should not be used as a solvent, cleaner, grill starter or for any other purpose other than the engine. Day tanks. The day tank is located between the bulk material storage tank and the diesel engine. Fuel is transported from bulk material storage to the day tank via the bulk material feed pump. Fuel from the day tank is routed to the diesel engine through the engine-driven fuel pump mounted on the engine assembly. 2. A double-walled surface secondary containment type overflow control tank is illustrated here, which is located away from the property line. Courtesy: Pxfuel G20 – This 12VDC has 20GPM capacity and can operate efficiently at temperatures ranging from -20°F to 125°F.

This mobile pump carries gasoline (up to 15% alcohol blends such as E15), diesel fuel (up to 20% biodiesel blends such as B20) and kerosene. OSHA requirements are defined by laws, standards, and regulations. Our interpretative letters explain these requirements and how they apply to particular circumstances, but they cannot create additional obligations for employers. This letter represents OSHA`s interpretation of the requirements under discussion. Please note that our enforcement guidelines may be affected by changes to OSHA rules. We also update our guidelines from time to time in response to new information. To stay informed of these developments, you can visit the OSHA website at The day tank is needed when the engine-driven fuel pump cannot draw fuel from the fuel tank due to distance or altitude issues.

The day tank is also used to ensure efficient fuel flow to the engine by eliminating an externally induced print head generated by the position of the bulk tank or bulk material delivery pump. The day tank also serves as a heat sink to collect hot, unused fuel, which is returned from the engine via a radiator. According to a spokesperson for the National Biodiesel Board, „blending ethanol into diesel fuel produces fuel that does not meet the ASTM D975 specifications for diesel fuel.“ The spokesperson said biodiesel is „a clean alternative to diesel fuel“ made from a wide range of renewable resources, including soybean oil, animal fats and recycled cooking oil. Biodiesel can be used alone or blended with petroleum diesel. Tank Filling – Use a tank suitable for outdoor use and bearing a UL (Underwriters Listed (UL) stamp. Tanks of this type can hold large amounts of fuel for up to weeks or even months. Therefore, minimizing refills reduces the risk of spills, leaks and fire. Leave room for expansion, so the tanks never fill more than 95% of their capacity. 1. Diesel generators are regularly used to provide backup power to commercial, industrial, medical and educational facilities. They are also used in power plants to provide standby power and black start capability. Courtesy of TAI Engineering ventilating bulk diesel storage tanks.

Bulk diesel storage tanks should be equipped with a vent line to prevent the formation of vacuum or overpressure in the tank during tank removal or filling or due to changes in atmospheric temperature. The drain pipe must be emptied into a secure room at least five feet from building openings and at least 15 feet from motorized ventilation air intake devices. Design standards for bulk diesel storage tanks. For diesel generator sets, the bulk storage tank is typically an atmospheric tank designed and constructed in accordance with the American Petroleum Institute (API) Welded Tanks for Oil Storage Standard 650. These tanks can operate at atmospheric pressure up to an overpressure of 1.0 psi (6.9 kPa), but must be ventilated to avoid vacuum. Other design standards may be used, but pressure limits shall be checked to prevent deformation of the tank hull during operation. The bulk storage tank may also be designed as a low-pressure tank according to API 620 Design and Construction of Large, Welded, Low-Pressure Storage Tanks or as a pressure vessel according to Section VIII of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Receptacle Code. 29.

January 2004 Mr. Dennis Vance Dennis Vance, LLC 711 Low Gap Road Princeton, WV 24740 Re: 29 CFR 1926.152(a), (f) and (g); §1926.155(a) and (l); and Standard 3-4.1A Mr. Vance, I am writing in response to your letter dated July 31, 2003, addressed to the Occupational Safety and Health Administration (OSHA). They ask about the requirements for storing and handling gasoline on a construction site at 29 CFR 1926.152. Your letter was forwarded to this office for processing on August 20, 2003. We apologize for the delay in responding. Question 1: Can gasoline from a five-gallon safety box approved by Underwriters` Laboratories be released into the fuel tank of a tool such as a target saw, weeder or 5 kW generator during a construction contract? General requirements for the handling and use of flammable and flammable liquids such as gasoline are specified in 29 CFR 1926.152(a): Ethanol diesel fuel storage tanks must be equipped with a flame arrester at the vent pipe outlet. This is because ethanol diesel fuel is a flammable liquid with a low flash point. By following OSHA`s guidelines above and educating your entire crew on proper protocols for storing and transporting fuel, you will ensure a safe and compliant construction site. Aboveground fuel tanks can be a convenience for businesses that often need to refuel company vehicles, construction vehicles, lawn mowers, and power tools.

Aboveground fuel tanks can also pose significant risks of loss in the form of fire, explosion, pollution and theft. If your company has or plans to install an aboveground fuel tank, you should consider the following: Installation of diesel storage tanks for bulk. Bulk tanks can be installed above ground, in a storage tank vault, underground (directly buried) or in a storage storage building. These are requirements for the storage of flammable and flammable liquids such as gasoline or diesel, as described by OSHA.
