In 2010, it was reported that a first responder was admitted to hospital after exposure to ammonia gas when responding to an ammonia leak at an arena.
In 2011, it was reported that three employees received injuries when ammonia refrigerant vapour was released at an arena. It was reported that two employees (operators) walked into ammonia vapour when they walked outside to investigate. The third employee (not an operator) reported exposure to ammonia. Approximately one year after the incident and investigation, Technical Safety BC learned indirectly that the third employee’s injuries were more serious than initially reported. This employee experienced chronic effects that impacted the employee’s respiratory systems.

In June 2015, three employees at a recreational facility were exposed to ammonia vapour when an operator in an adjacent building was purging an ammonia line.
In September 2015, an operator was attempting to add oil to the compressor when the operator was exposed to ammonia vapours. The operator was taken to hospital for treatment.
