Incident at WINNIPEG / JAMES ARMSTRONG RICHARDSON INTL MB (CYWG) (Electrical problem, ATM - other)


2001-09-05: UPDATE ANS and Airspace reported that the building fire alarm activated due to a water leak from the mechanical room onto one of the ceiling detectors, which eventually failed and caused the alarm. Work is in progress in replacing the current Halon protected areas with a new sprinkler system. A new fire alarm panel was in operation at this time but not handed over. Final system tests and commissioning targeted for completion this Wednesday. There were problems in locating the failed detector and the room where detector was located (not all documentation was in place nor the accompanying graphics portion of the alarm panel, which would have aided us in finding the room). Consequently, there was an extended response time to declare all clear. As well, repeated attempts to re-set the alarm (which caused the fire alarm panel to sense problem detector again and put building back into alarm condition) was attributed to lack of confidence on status of building. The above resulted in an extended response in locating source of problem. Documentation and procedures are being reviewed and updated.
2001-07-30: The Winnipeg ACC operations room fire panel went into alarm at 1740Z on July 29. Audio and strobe alarms activated. Pre-evacuation procedures were instituted. IFR departures within the Flight Information Region were suspended, adjacent ACC's were notified and requested to provide procedural separation. The alarm was stood down and the FIR returned to normal operations at 1830Z. All agencies advised. The cause of the alarm is unknown.
