    An initial progress report by the Major Incident Investigation Board on 21 February 2006 did not go into the causes of the explosion, but summed up the event and the immediate reaction from the emergency services. [22] [34] A second progress report, published on 11 April 2006, looked at the environmental impact. [11]

    en.wikipedia.org/wiki/1,1,1,2-Tetrafluoroethane

    1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...

  4. Carbon tetrachloride - Wikipedia

    en.wikipedia.org/wiki/Carbon_tetrachloride

    Being a good solvent for many materials (such as grease and tar), carbon tetrachloride was widely used as a cleaning fluid for nearly 70 years. It is nonflammable and nonexplosive and did not leave any odour on the cleaned material, unlike gasoline, which was also used for cleaning at the time. It was used as a "safe" alternative to gasoline.

  5. Dichloromethane - Wikipedia

    en.wikipedia.org/wiki/Dichloromethane

    Abundances are given as pollution free monthly mean mole fractions in parts-per-trillion. Dichloromethane is not classified as an ozone-depleting substance by the Montreal Protocol. [43] The US Clean Air Act does not regulate dichloromethane as an ozone depleter. [44] Dichloromethane has been classified as a very short-lived substance (VSLS).

  6. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    Ammonia is used in numerous different industrial applications requiring carbon or stainless steel storage vessels. Ammonia with at least 0.2% by weight water content is not corrosive to carbon steel. NH 3 carbon steel construction storage tanks with 0.2% by weight or more of water could last more than 50 years in service. [141]

  7. Selenium - Wikipedia

    en.wikipedia.org/wiki/Selenium

    Selenium pollution might impact some aquatic systems and may be caused by anthropogenic factors such as farming runoff and industrial processes. [100] People who eat more fish are generally healthier than those who eat less, [101] which suggests no major human health concern from selenium pollution, although selenium has a potential effect on ...

  8. Nitrogen dioxide - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_dioxide

    Nitrogen dioxide is a reddish-brown gas with a pungent, acrid odor above 21.2 °C (70.2 °F; 294.3 K) and becomes a yellowish-brown liquid below 21.2 °C (70.2 °F; 294.3 K). It forms an equilibrium with its dimer , dinitrogen tetroxide ( N 2 O 4 ), and converts almost entirely to N 2 O 4 below −11.2 °C (11.8 °F; 261.9 K).
