Ammonia is commonly used in mechanical refrigeration systems, including those found in ice rinks. Ammonia is used in liquid form in these systems but becomes a gas once it is released into the air.

The Canadian Centre for Occupational Health and Safety says ammonia is a colourless gas that is very toxic if inhaled and can cause death.

Symptoms of ammonia poisoning may include coughing, shortness of breath, difficult breathing and tightness in the chest. The centre also says symptoms may develop hours after exposure and are made worse by physical effort.

In addition to being used in ice rinks, ammonia is used in fertilizer and to make plastics, fibres and other chemicals.

Dealing with weather

Earlier Tuesday, the City of Fernie had posted to its Facebook page that the arena would be closed for the day "while crews complete emergency repairs to the refrigeration plant." Fire chief Ruiter said it wasn't immediately apparentthat ammonia was the cause of the emergency.
