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.
A student determines the amount of tetrachlorethylene in a contaminated well water using a purge and trap technique. The student takes 150.0 mL of the well water, spikes the well water with 100 microlitres of 50 ng carbon tetrachloride/mL and purg..
