On April 27th, 2004, National Institute for Occupational Safety and Health (NIOSH) researchers conducted a follow-up evaluation of an exhaust stack designed to reduce carbon monoxide (CO) emissions and prevent exposures on houseboats at Sumerset Acquisitions LLC in Somerset, Kentucky. This work was conducted to evaluate permanent design changes that were made to the Sumerset stack since the August 2003 CO evaluation documented in the NIOSH report titled, 'An evaluation of factors that might influence stack performance to prevent carbon monoxide poisonings from houseboat generator exhaust.' Although the exhaust stacks evaluated during the August 2003 NIOSH study performed well, the initial design included several factors that influenced the stack performance. This report provides a brief description of the design changes, methods, results, and conclusions from the follow-up evaluation. |
