  • Hyperion case study - UVC lights enhance air quality

    Located at the center of the Hyperion Wastewater Treatment Plant in Los Angeles, the Pregerson Building was experiencing indoor air quality (IAQ) problems. Built in 2002 to house nearly 400 city employees, the facility rapidly became the source of complaints about poor IAQ and odors. An engineered solution that incorporates both an odor control unit and supplemental ultraviolet- C (UVC) lights in ...


  • How to Get Higher Acceptable Indoor Air Quality Anywhere

    The quality of the indoor air we breathe is a concern for everyone, especially those in urban environments where contaminant and particle levels are higher due to nearly constant exposure to things like automobile and truck exhausts, construction, and fumigation. Unfortunately for most people, when it comes to the quality of the air in the buildings where they spend most of their time, ...

  • Asbestos Awareness: Preventing a Hazardous Workplace

    Many on-the-job hazards are obvious... leaking machinery... dangerous chemicals... slippery floors. However, other hazards aren't so obvious. There may be no visible signals that they are present at all. That's why Asbestos is often known as 'the silent killer.' While you often can't see, taste or smell it..., prolonged periods of exposure to Asbestos can cause lung disease, cancer... even death. ...
