    Product Appearance Odor Special Behavior Hazards
    Natural Gas Combustible mixture of hydrocarbon gases which is colorless and shapeless No odor will be detected unless an odorant is added for shipping
    • Low density and lighter than air
    • In an open area, it rises into the atmosphere and dissipates
    • In an enclosed area, natural gas will collect first overhead
    • Extremely flammable and explosive
    • Suffocation can occur if gas displaces the oxygen in an enclosed area
    Natural Gas Liquids (NGL) Steam-like cloud or a frost-like appearance on the ground Similar to gasoline, but much stronger and extremely unpleasant
    • Heavier than air
    • Stays close to the ground in low-lying areas
    • Extremely flammable and explosive
    • Suffocation can occur if gas displaces the oxygen in an enclosed area
    Hydrogen Sulfide (H2S) Colorless and shapeless Smell similar to rotten eggs
    • Slightly heavier than air
    • Settles particularly in low-lying areas
    • A mixture of H2S and oxygen (air) is flammable and explosive.
    • Toxic in high concentrations
    • Paralyzes the sense of smell in higher concentrations
    Product Appearance Odor Special Behavior Hazards
    Crude Oil Black liquid Similar to gasoline or diesel fuel*
    • Flows with the land profile
    • Flow depends on temperature and viscosity. Can be thick and slow moving or light and able to move quickly.
    • Extremely flammable and explosive, especially when first released
    • Suffocation can occur if gas displaces the oxygen in an enclosed area
    • Benzene is a toxic and volatile element in crude oil; benzene levels in crude vary greatly
    Synthetic Crude, Condensate or Refined Products Light brown or yellow liquid Similar to gasoline or diesel fuel*
    • Flows with the land profile
    • Extremely flammable and explosive
    Natural Gas Liquid Steam-like cloud or frost-like appearance on ground Similar to gas, but much stronger and extremely unpleasant
    • Heavier than air
    • Stays close to the ground in low-lying areas
    • Can displace oxygen
    • Extremely flammable and explosive
    Diluent Clear to brown liquid Sulfur-like or rotten egg odor
    • Less dense and more fluid than crude oil
    • Extremely flammable, especially if vapors from the liquid are ignited
    • Potential explosive hazard if vapors seep into enclosed spaces
    • Suffocation can occur if gas displaces the oxygen in an enclosed area

    *Some crudes and condensates contain hydrogen sulfides (H2S), which have a rotten egg smell and are toxic in high concentrations.
