DynCorp Report
Summary of Basic Testing, including: Emissions, Mercury Testing, etc. on Tempico's Rotoclave®

In 1997, NIOSH (the National Institute for Occupational Safety and Health) of the U.S. Centers for Disease Control and Prevention (CDC), had the Rotoclave® evaluated for health and worker safety at an installed site. This was done under a Cooperative Research and Development Agreement (CRADA). The organization they had perform the tests was DynCorp of North Carolina. DynCorp, in summary, stated the following specifics about the Rotoclave® in their March 1998 report:

A."Chemical emissions: Testing was conducted for mercury, other metals, aldehydes, volatile organic compounds (VOC's), and indoor air quality factors. None of these potential pollutants was found at or near applicable exposure limits. Mercury levels were all below the OSHA permissible exposure Limit (PEL). Indoor air quality monitoring was conducted during waste processing for temperature, relative humidity, carbon dioxide (CO2) and carbon monoxide (CO). All were within acceptable limits, with CO2 and CO well below OSHA specified limits."

B."Particulates and Aerosols: Aerosols were evaluated with optical monitors in the exhaust stream of the waste treatment area immediately before, during, and after a Rotoclave® discharge event, and were found to be at acceptable levels."

C."Biological Hazards: The Rotoclave® treatment process was evaluated for potential biological emissions by identification of potential emission points, with subsequent volumetric bioaerosol sampling for indicator bacterial spores during treatment cycles with spiked and non-spiked waste. Results showed no detection of bacterial indicator spores in any bio-aerosol samples collected at potential emission points during waste treatment cycles."

D."Noise: Data show that operation of the Rotoclave® during waste processing did not exceed the OSHA PEL for noise."

E."Conclusions: A comprehensive study using environmental and personal sampling methods to identify and quantify hazards to medical waste treatment workers during operation of the Rotoclave® showed no metals, chemicals, particulates, or noise at or near applicable exposure limits, and confirmed the absence of potential biological emissions."
