Continuous monitoring of Ammonia, Carbon monoxide, Nitrogen dioxide and Propane (or Methane) in ice rinks

Ice arenas have multiple gas hazards in various locations throughout the facility. Ammonia is commonly used in the chiller/mechanical room and if a leak were to occur, it would become a corrosive, toxic gas. At the ice surface level, gasoline, propane, natural gas (and sometimes diesel) powered equipment such as an ice cleaning machinery and ice edger produce exhaust composed of carbon monoxide and/or nitrogen dioxide. Other fuel powered equipment such as floor sweepers, lift trucks and other vehicles idling in close proximity can add to the CO and NO2 levels. In the stands, cheering spectators watch the game and produce Carbon dioxide as they breathe.

  • Multiple gas hazards throughout the facility require several types of gas detectors to protect workers, spectators and athletes​
  • Recommend an Explosion Proof gas detector in the parking area of the ice cleaning machinery​
  • Outside the chiller room should be a Controller with a strobe and manual shut off switch to meet code requirements


  • Ammonia (NH3)​
  • Carbon Monoxide (CO) and Nitrogen Dioxide (NO2)​
  • Propane (C3H8) or Methane (CH4) or Hydrogen (H2)​
  • Carbon Dioxide (CO2)

To meet code requirements, the FCS should be equipped with a top mounted strobe and a manual shut off switch. At specified alarm levels, the ventilation system can be activated as well as any remote devices such as the Remote Strobe / Horn combo (RSH-24V-R or RSA-24V) and the manual shut off switch can be used to shut off the chiller equipment.
