  • Case study of odor and indoor air quality assessment in the dewatering building at the Stickney Water Reclamation Plant

    Indoor air quality (IAQ) and odors were determined using sampling/monitoring, measurement, and modeling methods in a large dewatering building at a very large water reclamation plant. The ultimate goal was to determine control strategies to reduce the sensory impacts on the workforce and achieve odor reduction within the building. Study approaches included: (1) investigation of air mixing by ...

  • If you can`t stand the CO2, get out of the kitchen - part 1

    There are two potentially dangerous types of gas in a commercial kitchen: 1) the flammable ones used for cooking (e.g. methane/natural gas; propane/liquefied petroleum gas); and 2) the noxious, gaseous products of combustion such as carbon monoxide, carbon dioxide and hydrocarbons. It would be good to know how to avoid them. But a search for advice on kitchen ventilation threatens to drown the ...

  • Welding Fumes and the effects of Manganese

    The potential risks of welding operations include the potential to breathe in metal fumes and toxic gases. Fume particles are formed from the vaporisation of molten metal that occurs during the process. These particles are very fine in size and may join together to form larger particles.. The biggest risk is exposure to the manganese contained in fumes that are given off during welding. ...
