DIESEL V2000 a SAFETY DATA SHEET Vapour (vapor is the US spelling) is the more technically correct term. LPG gas (vapour) is heavier than air. Flammable, explosive amounts of vapors can therefore collect around floors or in basement structures, pits, sewers, sumps and trenches while people nearby remain unaware. Hazards. Being heavier than air, vapors may travel long distances to an ignition source and flashback. At this temperature, a combustible (explosive) mixture of vapour and air is created directly above a flammable liquid. Note that LPG gas is also referred to as "LPG vapour". the energy density of hydrogen is equal to 33.6 kWh of usable energy per kg, versus diesel which only holds about 12-14 kWh per kg. splash filling. #2 because vapors and particulates that pass through the eductor system can generate static, the eductor system must be bonded to a grounded Diesel is thicker, heavier, and oiler than gasoline and has more energy density. Ethanol's specific gravity is 0.79, which indicates it is lighter than water but since it is water-soluble it will thoroughly mix with water. Other hazards The vapour is heavier than air; beware of pits and confined spaces. Butane is 2.08 times heavier than air. In its vapor form, diesel is very dangerous and can catch fire (or explode) easily in the presence of an accelerant such as fan air or oxygen. No, I haven't seen a gas tank sensor - it may be power limited to such an extent that the vapor cannot be ignited, I dunno. Flammable vapours may be present even at temperatures below the flash point. Materials lighter than air have vapor densities less than 1.0 (example: acetylene, methane, hydrogen). In contrast, the density of Air is 1.225 kg/m 3 (at 15C and sea level). You would need to heat it to get it to evaporate and then, with the right fuel-air mixture, it can explode. Impurities such as water vapour . Kerosene and Diesel Fuel are termed Combustible because their Flashpoint is greater than 100 degrees F.
