Supporters of a bill that would improve the air in ice skating rinks are rallying at the Capitol Thursday.
The bill from Sen. Ellen Anderson of St. Paul would require indoor ice arenas to install air monitoring devices and keep carbon monoxide levels below a set point.
Zambonis and other ice-grooming machines give off carbon monoxide.
Anderson's proposal comes after youth hockey players and ice skaters have gotten carbon monoxide poisoning after rinks are groomed. A former professional ice skater who suffers from chronic carbon monoxide poisoning will also appear at the rally.
The bill would also require training for those who operate ice grooming machines.
