Indoor ice rink facilities are designed to bring family fun indoors for year around comfort and activities.  There are several unseen hazards that are inherent in the design of these facilities.  Ammonia is the typical coolant used for the ice surface and if a leak occurs is could be toxic and perhaps deadly to guests or maintenance personal.   The equipment used to maintain the ice, resurfacers and edgers, are typically powered by propane, natural gas and sometimes diesel fuel. This equipment will give off toxic gases in the form of carbon monoxide CO and Nitrogen Dioxide NO2 in the arena area and the vehicle parking garage.

The ice rink mechanical room is the primary location of the ammonia refrigeration equipment. Usually a brine solutions is used for under ice refrigeration with the ammonia providing cooling of the brine to about 25-30oF. The ammonia room should be fitted for ammonia gas detection near ceiling height as ammonia is lighter than air.

Ice resurfacing vehicles and ice maintenance equipment garages and storage areas should employ gas detectors for the type of fuel they use (Propane, Butane or combustion) to alert of spills or leaks that could be dangerous to maintenance personnel or ignite.  In addition, these areas should be fitted with gas detectors for carbon monoxide (CO) and nitrogen dioxide (NO2) to protect operators and maintenance personal from toxic gases as the equipment is being moved or idling.
