June 23, 2020
Location: Port Alberni
Regulated industry sector: Boilers, PV & Refrigeration - Refrigeration system
Two certified individuals were executing seasonal plant startup activities in an effort to generate an ice surface. The ammonia release initiated alarms, equipment shutdown, plant evacuation of staff and emergency services to attend the site. The loss of containment was likely caused by relaxation of the mechanical fasteners.
