#3 Describe how the chemical characteristics, production methods, uses, and associated unique hazards of hydrogen can affect the safety of an environmental health and safety (EHS) and fire science (FS) professional.
#4 A nursing home is installing their own bulk oxygen system due to their large volume of consumption. OSHA regulation 29 CFR 1910.104(b)(2)(iii) requires owners of bulk oxygen systems to provide noncombustible surfacing in areas where liquid oxygen might leak during operation of the system or during the filling of a storage container. If the nursing home provides an asphalt surface in areas where oxygen could potentially leak, will it be in compliance with the workplace regulation regarding oxygen? Explain your answer.
#5 Although coal is no longer the favored energy source, U.S. coal mines still produced close to a billion short tons of coal. Contrast the properties of three different forms of coal. Discuss at least five chemical products, including activated carbon, formed from coal and their related health hazards. Describe DOT’s recommended response actions to incidents involved the release and burning of coal.
