Indoor Ice Arenas
The first recorded episode of illness among children skating in a Minnesota ice arena was reported in 1966 when girls, ages 7-11 years old, developed headaches and nausea while figure skating. It was at this time that widespread use of machines with internal combustion engines to resurface and maintain ice began.
Internal combustion engines are still used to groom and resurface the ice in arenas. To ensure the protection of public health, the Minnesota Department of Health regulates the air quality in ice arenas. Ice arenas that use internal combustion engines must be certified, and are required to monitor and maintain air quality.
