Diesel Generator Exhaust has always been a problem. In the past the nuisance was mostly the smell. When a hospital would fire up the emergency diesel for the monthly inspection people would complain as diesel exhaust was re-entrained through outside air intakes.
Now it’s more of an issue. Diesel engine exhaust is now classified as carcinogenic to humans (Group1). The reclassification was announced on June 12 earlier this year by the International Agency for Research on cancer (IARC). Previously (1988), IRAC had classified diesel exhaust as probably carcinogenic to humans (Group 2A). For more information on IARC’s evaluation of diesel and gasoline engine exhausts, visit the IARC website.
High Plume Dilution Fans work well to rid a building of Diesel Generator Exhaust. A special High Temperature Tri-Stack fan is manufactured by Strobic Air. These fans are available in rigid steel construction designed specifically for high temperature applications (such as emergency diesel generator, furnace or boiler room exhaust). Tri-Stack high temperature exhaust fans are UL certified for operation at 750°F for up to 2 hours without the need for outside air dilution, and incorporate chemical resistant high temperature coatings.
