An indoor ice skating rink is an enclosed space with intermittent air pollutant emissions from fuel-powered ice-resurfacing equipment, such as a resurfacer and an edger. Exhaust gases discharged from the resurfacing equipment actually include significant quantities of carbon monoxide (CO) and nitrogen dioxide (NO[sub 2]) which may induced adverse health effects. Carbon monoxide exposures in ice skating rinks resulting from malfunctioning ice resurfacing equipment were first reported more than twenty years ago. Attempts to reduce emissions of CO and NO[sub 2] form resurfacing equipment, such as the extended exhaust pipe, operation of the air recirculation system or reduced resurfacer operation, appeared not to be effective for maintaining the air pollutant concentrations below guidelines. Even though improved indoor air quality was obtained by the combination of the full operation of the air exhaust system and the reduced number of resurfacer operations in this investigation, these methods may be impractical for most skating rinks. Replacement of the fuel-powered resurfacer with a battery operated resurfacer is recommended. If replacement is not feasible, then increasing the air ventilation rate is recommended as a second choice. 10 refs., 1 fig., 1 tab.
